For The first warning: Either you can avoid it OR see referenced file "
mitf.tcl", understand the way channel is defined.
Second warning could have various reasons:
a) error in code (most likely after you did the modification)
b) error in path (unlikely but probable)

Hi Peter,

One way to introduce delay in routing could be to schedule outgoing packets
with some delay, exemple:
Scheduler::instance().schedule(target_, packet, delay); instead of
Scheduler::instance().schedule(target_, packet, 0.); which is done now in
routing components (aodv.cc for example).

Hope it helps.
Bye.
Hajer.

Hi all,
I'm trying to simulate multiple TCP agents that transfer data simultaneously.  
However, i want each one to transfer certain amount of data, How do i specify 
that? and also how can I measure the time it takes for all agents to 
completely transfer the specified amount of data (and also time for each 
agent?)?

Subject: [ns] Bug: "Scheduler: Event UID not valid!"
Message-ID: <438ED653.2030505@tk.uni-linz.ac.at>

Hi!

I am writing a new routing protocol for MANETs!

When I run a simple test for 50 mobile nodes, it generates error:
"Scheduler: Event UID not valid"!

I have read some discusses on mailing-list achieve [Jan 2005,
http://mailman.isi.edu/pipermail/ns-users/2005-January/subject.html] and
test for alternative proposed there. Here are results:

My computer: Suse Linux 9.3, test for NS-2.28, NS-2.27, NS-2.26

1. Original NS-2.26-28 (ad-hoc routing/MAC-802.11)
It stops at 267sec/total 900 secs simulation

2. Modified MAC-802.11 using fixed bug from Maguolo Federico:
http://mailman.isi.edu/pipermail/ns-users/2005-January/047000.html
http://www.dei.unipd.it/wdyn/?IDsezione=2435
Still got the same error, but at longer time

3. Modified MAC-802.11 using package WLAN802.11a/b/g from Mike Moreton's
http://cvs.sourceforge.net/viewcvs.py/ns2-wlan-patch/#dirlist
Still got the same error, but sooner. Note that the speed becomes slowly!

>From these discussions, I know the problem is from scheduling at the MAC
layer, which will be partly affected by how events are scheduled in the
ad-hoc routing layer. This is why in AODV, a random time is used to
schedule the packets, esp. in broadcasting!

I try to schedule packets randomly, e.g. schedule(this, packet,
0.01*Random::uniform()) instead of schedule(this, packet,0.) and it runs
successfully!
Another point is broadcast periodically, also randomly:
e.g. schedule(this, &intr,
a*BCAST_INTERVAL+2*(1-a)*BCAST_INTERVAL*Random::uniform()) with 0<a<1,
instead of
schedule(this, &intr, BCAST_INTERVAL)

I test another senario with 100 nodes and it is OK!

But still getting same error when I change the radius (number of hops) of
broadcasting for building cluster!

I just run some tests and not sure the results!

Any discussion and helping are welcome!

You can output the trace info for each node to seperate files.

Are you sure some nodes have more than 50 packets in their queue at one
moment in time ?
Try it by decreasing the queue-limit even further, 50 still is a lot, it's
the default value if not mistaking.

sincerely,

Subject: [ns] R:  doubt regarding TCP throughput caluculation
Message-ID: <31970178.1133442439145.JavaMail.root@pswm3.cp.tin.it>

Anand,

the two formulas you are using are not the same.
Roughly, the 
first one gives you the goodput (amount of data actually received), the 
second one gives you the throughput (amount of data transmitted). The 
difference should be given by lost packets which are retransmitted.

However, you got two very different values, which means that: 1) TCP 
suffers from heavy losses, or 2) there's something wrong in the way 
received packets or average congestion window size or average RTT are 
calculated.

I also assumed that the badwidth is sufficient for the 
whole congestion window to be transmitted within a RTT, otherwise the 
second formula cannot be used.

Regards,

Marco Fiore

Ogg: [ns] doubt regarding TCP throughput 
caluculation


Hello everybody,
           I have one doubt...

I'm 
simulating a scenario like:
one TCP connection running between two 
mobiles in wireless network(UMTS).
I calculated the throughput as 
=total no of pkts rx/simulation time.
And we also no that

mean 
throghput=mean window size/mean RTT..
from simulation i got mean window 
size,mean RTT.
from this farmula if i compute the throughput,it is not 
matching with
the one computed  from simulation(total no. of pkts 
rx/simu. time).

I think it should match becoz I'm using both values 
which i got using
simulation(mean RTT,mean Window size).
what i mean is 
like the below one

 throughput  =total no of pkts rx/simulation 
time=mean window size/mean RTT


but
i got throughput  =total no of 
pkts rx/simulation time=3790/50=75.8

throughput  =mean window 
size/mean RTT=61.55/.149=412.75

so both values r no mathching.

Subject: [ns] ns-2 FAQ
Message-ID: <438F0B22.9070705@tomh.org>


             The Network Simulator ns-2: Frequently Asked Questions

    (This FAQ is also on the web at
    http://www.isi.edu/nsnam/ns/ns-faq.html.)



    _The mailing is is now subscriber only---please see the FAQ entry on
    "How do I post to the mailing list? Why was my post rejected?" for
    details._

      * _Where do I get ns?_

        From the ns web site at http://www.isi.edu/nsnam/ns/ns.html and
        the download page http://www.isi.edu/nsnam/ns/ns-tests.html.

      * _What platforms does ns run on and what kind of hardware do I
        need?_

        Please see "where to start" on the building ns web page:
        http://www.isi.edu/nsnam/ns/ns-build.html#start.

      * _What should I do if I have trouble downloading/extracting ns?_

        This question is answered in detail at
        http://www.isi.edu/nsnam/ns/ns-problems.html#downloading.

      * _What should I do if I encounter problems building ns?_

        Check:
          1. the README that comes in the distribution (very brief),
          2. the "installation problems, bug fixes and help" web page
             http://www.isi.edu/nsnam/ns/ns-problems.html,
          3. the archives of the ns-users mailing list
             http://www.isi.edu/nsnam/ns/ns-lists.html,
          4. post a bug report (see below)
             http://www.isi.edu/cgi-bin/nsnam/reportbug.cgi.

      * _What do I do after I successfully build ns?_

           + Put the path to your ns executable into your PATH environment
           + Put the path to your otcl into your LD_LIBRARY_PATH
             environment
           + Put the path to your tcl library into your TCL_LIBRARY
             environment

      * _Where can I find documentation for ns?_

        All documentation is linked from the main ns web page
        http://www.isi.edu/nsnam/ns/. Documentation includes a tutorial
        (originally from Marc Greis) and a reference manual (ns notes and
        documentation).

      * _Words, words, words... that documentation is nice, but where are
        some sample scripts I can start from?_

        Many sample scripts can be found in the ns distribution in
        ~ns-2/tcl/ex and ~ns-2/tcl/test.

      * _What protocols does ns support?_

        A lot! Almost all variants of TCP, several forms of multicast,
        wired networking, several ad hoc routing protocols and propagation
        models (but not cellular phones), data diffusion, satellite, and
        other stuff. See the documentation (described above) for details,
        or download ns and look.

      * _How do I know that ns correctly implements these protocols?_

        Ns has validation tests that cover many protocols, see
        http://www.isi.edu/nsnam/ns/ns-tests.html. However, ultimately
        users are responsible for verifying that ns is accurate for their
        purposes---since we cannot foresee all the ways ns may be used, we
        cannot test all cases with all inputs.

      * _Are there any contributed/additional protocols not in the main
        distribution?_

        Yes, please see the contributed code web page
        http://www.isi.edu/nsnam/ns/ns-contributed.html. The mailing list
        archives can also be helpful (see below).

      * _How should I get started doing something (like implementing a new
        protocol or trying an experiment)?_

        We recommend that you look through the tutorial (see
        documentation, above), then start with an example program that is
        most similar to yours (in the tutorial, or in tcl/ex or tcl/test
        in the distribution), and then start changing things.

      * _What should I do to compile ns to reflect my changes if I've
        modified some .cc or .h files?_

        go to ns directory and run "make" or "make depend; make"

      * _How do I subscribe to the ns-users mailing list? How do I search
        old list archives? I can't take any more---how do I get off this
        list?_

        To subscribe or unsubscribe, see
        http://www.isi.edu/nsnam/ns/ns-lists.html. The list archive is at
        http://www.isi.edu/nsnam/ns/ns-lists.html.

      * _How do I post to the mailing list? Why was my post rejected?_

        As of June 2004 the ns-users lists allow posts from _subscriber
        only_. If you're not a subscriber, your posts to the list will be
        rejected. (This is unfortunately necessary to dispose efficiently
        of spam; manual filtering is too expensive.) We realize that the
        list is high traffic, so if you wish to post to the list without
        receiving messages on it, please subscribe and select the _no-mail_
        option for your subscription.

        For details about the mailing list including mailing-list specific
        FAQ (for example, what if you're subscribed but still can't post),
        please see http://www.isi.edu/nsnam/ns/ns-lists.html.

      * _Did my post appear on the mailing list? (Or, why didn't my post
        appear on the mailing list?)_

        See the http://www.isi.edu/nsnam/ns/ns-lists.html web page for
        help debugging mailing list problems.

      * _What if I have a question that's not answered here?_

        If you've checked the installation problems and bug fixes web page
        (http://www.isi.edu/nsnam/ns/ns-problems.html) and there's no
        answer to your question, you may want to file a bug report or post
        a question to the ns-user's mailing list.

        First, you should check the archive of the list at
        http://www.isi.edu/nsnam/ns/ns-lists.html. Your question may
        already be answered there.

        If not, you can post a bug report using the web form at
        http://www.isi.edu/cgi-bin/nsnam/reportbug.cgi.

        If your question is NOT about ns implementation bugs, you may wish
        to post to the list. First you should subscribe. Subscription
        instructions are at http://www.isi.edu/nsnam/ns/ns-lists.html.

        _Please note that mail sent to the list is publicly distributed
        and archived. _If you have concerns about your message being made
        public (spam harvesting of your address), please consider that
        _before_ posting. We cannot remove messages from reciepient's
        mailboxes or the public archive after they're posted.

        When posting bug reports, please _always_ include information
        including at least (the bug report form includes spaces for
        these):
           + what version of ns you're using,
           + what operating system you're running on (not just Linux or
             Solaris, but RedHat version 7.0 or Solaris 2.4---send us the
             output of "uname -a"),
           + what specific behavior you see (if ns doesn't compile, what's
             the specific error; if TCP does something strange, what
             exactly did it do [send a pointer to a packet trace]),
           + what behavior you expected to see (if ns doesn't compile this
             is obvious, but if TCP does something strange, why is it
             strange, where is the TCP spec violated?),
           + pointers to your script detailed output files,
           + a statement that "yes, I've read the FAQ, ns-problems page,
             and manual and I couldn't find the answer there" (or a
             statement about why you didn't do that yet :-)

        Soo-Hyun Choi observed from posts to the list: _Sometimes, I see
        this list is filled with the questions with: 1) asked many times
        before 2) hardly understandable what this guy is asking 3) too
        easy to find an answer over a few clicks over the Internet 4)
        soliciting to do their homework in a simple way by asking in this
        list 5) easily seekable an answer by contributing a couple of
        hours of reading the ns-manual 6) etc, etc. _

        _As many of us in this list are doing an advanced degree, it would
        be suggested to read the following article in order to raise a
        useful/meaningful question in a smart way.
        http://www.catb.org/~esr/faqs/smart-questions.html _

        This is _very_ good advice, since asking the Right Question is
        very likely to get a good/helpful answer, while asking a question
        poorly. For example, think about how you would answer these two
        questions: _"Ns doesn't work for me, it crashes. Help."_ as
        compared to _"I get a segmentation fault when running test script
        test-suite-webcache on Mandrake 10 Linux. The backtrace is on my
        web page at www.someu.edu/~someone. It looks like it passes in the
        on-line test suites, but it fails for me. Am I doing something
        wrong?_

        A reminder about mailing list etiquette:
           + Please check the web pages and list archives before posting
             your question.
           + Please keep the body of your post to simple ASCII, not HTML.
           + Please do _not_ send large attachments (if what you have is
             bigger than a few kilobytes, put it on a web page and send a
             URL)
           + Before posting a question like "did people see my post" or
             "the list seems down", please check the archives (you can
             answer this question more accurately by checking yourself
             rather than asking).
           + Please don't post subscribe/unsubscribe requests directly to
             the list, use the lists' information page. (see the web page
             mentioned above for details).

Hello everybody,
I am trying to do the routing protocol CHAMP work in ns-2.28. I set the
parameter value "adhocRouting" of wireless node as "CHAMP" in the simulation
script, but when running the script, it is reported the following message:
"Wrong node routing agent!". Could anybody help me to solve this problem?

Can you give more details on what you are trying to do..??

A naive answer is just "connect" source and destination and send "traffic"
type.

Hi Everyone

Im implementing routing algorithms for sensor networks and this problem is 
primarily concerned with interaction between Application and Agent in ns-2 
ver 2.29. 

In fact I did find some questions of very similar nature in the archives of 
the list but there are no definite answers. It'll be great help if someone 
can help.

Background:
-----------
My prime objective is to simulate an evoironment where applications are 
running on each of the sensor nodes, application data is passed to the agent 
which disseminate it to the network using a particular strategy. Moreover, 
on reciviving data, agent forward it to the attached application.

For this purpose I implemented a new routing agent, T-Agg, and was able to 
run simulations succesfuly using this routing agent. Later I developed an 
application (inheriting from Class Application) and in the Tcl script 
created multiple application instances and attach each of these to unique T-
Agg agent instances (using "attach-agent") which are in turn connected to 
nodes.

The Question:
-------------
For agent up-calls to the application I plan to use app_ pointer provided by 
the class Agent which is set in the attach-agent command handler.

The main trouble is that even though I do attach-agent in the Tcl correctly, 
app_ pointer of T-Agg objects soon become void. When I check the app_ of any 
T-Agg object before starting packet dissemination it give me correct 
reference. But as soon as the packet dissemination is started app_ pointers 
of all the T-Agg objects seem to reset or become void and hence as soon as 
agent up-call is reached program exits with a Segmentation Fault.

I will be looking forward to any suggestions/comments/feedback regarding 
this unpredictable behavior of app_ pointers. Or any other comments 
regarding a better/alternate way of reaching the same objective.

Thanks a lot

Hi

        I want to implement a new adhoc routing protocol in ns2. So, i made
some new .cc and .h files and started compiling. I made necessaray changes
to make file and i issued the make command. I received some errors in the
process of compilation.

 After when I tried to run a simple tcl file (simple-wireless.tcl) which i
successfully run previously... it is giving an error

bash: ns: command  not found.

So I tried to locate ns.exe file. But I am not able to find it... one short
cut is there in bin directory, but its target is not specified... How can I
get ns.exe file back ? Is it happened due to the compiler error I received ?

Thanks in advance

It should be in the ns-allineone-2.28/bin ... if not, you might have deleted
it, like I did once.
Reinstall or restore from a copy/back-up, which I recommend to everybody !

a) use better descriptive subjects.

That happens a lot in NAM traces.
Basically, some parts of the NAM trace code output the time values with
different float precisions, eg: (just examples)

	fprintf(file, "%f", time);

	fprintf(file, "%7.7df, time);


this results in trace events that seem to be not ordered in time for NAM. 
However, these only slightly affect the visualization of the simulation.

If you take the time to find which fprintfs suffer from this problem, please
send this info to the developers.

Hej everybody,

I am a new user and I need some clarification.

I have a dumb-bell topology with an input traffic as CBR on UDP, defined by a
packet size of, say 50. I know the 50 bytes packet is concerned only to the
payload and I presume that NS2 attaches the headers IP/UDP by default. Now I
have two questions;

1. How do we confirm if the headers are attached? Is there any place where I
need to activate the operation of attaching the specific headers?
2. What about RTP header, how to attach it? Is it true when UDP is specified,
RTP header is assumed by default in NS2.

Your response would be greatly appreciated.

Thank you.

Best regards,
Deepak

Yes, if you got compile erros, it wouldn't create ns.exe - hence the error.

The solution is to get rid of the erros, (worst case - undo your changes) & 
compile successfully! In my experience, it has always been a good idea to 
back up the entire ns-2.28 folder prior to making any major changes.

Subject: [ns] Desperate cry for help: beacon interval configuration in
	802.11b infrastructure mode
In-Reply-To: <20051202151752.E97762CEA4E@saffron.mlab.t.u-tokyo.ac.jp>
Message-ID: <20051202152753.E3A362CEA41@saffron.mlab.t.u-tokyo.ac.jp>

Hi all,

I am sorry if my question has already been answered. Though I saw many
similar questions in the archive, I could not find any clear answer...

My question is how to configure beacon interval in IEEE 802.11b
infrastructure mode. Currently I am trying to simulate how much traffic load
affects beacon transmission in a negative way in the same channel. I want to
check beacon behavior, e.g. tx time, rx time, collision, etc...in a MAC
trace file, but I could not find out how to set up access points which
broadcast beacons with configurable interval.

Reading NS change log, it seems that IEEE802.11 infrastructure mode has been
implemented since ns-2.27.
http://www.isi.edu/nsnam/ns/CHANGES.html

I tried test-suite-wireless-lan-ap.tcl under
/ns-allinone-2.29/ns-2.29/tcl/test, but I could not see any beacon traces in
trace file.
I checked ns-2.29/tcl/lib/ns-default.tcl, but I could not find any default
value regarding beacon interval...

I also have seen three clues in the below source codes, but unfortunately my
poor knowledge was not enough to figure it out.

In ns-2.29/tcl/lib/ns-mobilenode.tcl
	Node/MobileNode instproc CFP { beacon_period cfp_duration } {
	       if {$mactype == "Mac/802_11"} {
        		       $self instvar mac_
        		       set ns_ [Simulator instance]
        		       set beacon_period [$ns_ delay_parse
$beacon_period]
               		set cfp_duration [$ns_ delay_parse $cfp_duration]
               		$mac_(0) cfp $beacon_period $cfp_duration
       		}
 	} 

In ns-2.29/tcl/ex/miptest.tcl
	# 6. For configurable parameters, see the constructors of these
modules
	#    for the "bind" statements; beacon period can be set by the
statement
	#    "<name of an Agent/MIPBS or Agent/MIPMH> beacon-period <beacon
period>".
	# some changes are made by Ya 2/99

In ns-2.29/tcl/lib/ns-mip.tcl
Agent/MIPBS instproc init { node args } {
	eval $self next $args
    	# if mobilenode, donot use bcasttarget; use target_ instead;
	if {[$node info class] != "MobileNode/MIPBS" && \
			[$node info class] != "Node/MobileNode"} {
		$self instvar BcastTarget_
		set BcastTarget_ [new Classifier/Replicator]
		$self bcast-target $BcastTarget_
	}
	$self beacon-period 1.0	;# default value
}

In fact, I tried to replace beacon with CBR, but in vain because of replied
ACKs. When I modified mac-80211.cc so that node does not reply ACK, I failed
to emulate beacon because of ARP packets...

Is there anybody here who knows how to configure beacon interval and see the
beacon frame in the trace file? Please help me. 

I am using ns-2.29 on FreeBSD 5.3
Thank you very much for your time and attention.

Best Regards,
Jaeouk

a) use better subjects:

You must use the right agent.
Use Agent/RTP. It should produce RTP + UDP headers

Message-ID: <a9457c930512020816i6f2c9618j9373ee57a1d3c520@mail.gmail.com>

My application is derived from the Class Application.
In my application, one mobile node will periodically broadcast to whole
networks. One way is to send message to all nodes in a for loop because the
node addresses are from 0 and increased by 1. The other way is to use the
IP_BROADCAST  as the destionation address. However, the second way doesn't
work. Does someone know how to solve this problem?

Sometimes, a node needs to send message to its neighbors(one hop distance).
Can I use the broadcast and set TTL in IP header as 1 to get it? In
addition, is there a method from which I can get a list of node's neighbors?

I have read the AODV source code and I know how to realize the above
functions in AODV. However, my code is on the application level and the
above functions seem difficult for me.

Could someone help me?

Thanks a lot in advance.

Check this FAQ in 
http://inesc-0.tagus.ist.utl.pt/~pmsrve/ns2/ns2_tips.html

How to known which Agents are implemented in NS2 / which protocols are
implemented in NS2
A very common question is to know what protocols are implemented in NS2. For
example, NS2 is well respected by having very good implementations of the
different flavors/options of TCP. However, to know exactly what agents
implement said protocols, one has two options:
a) look into the NS2 manual - AFAIK, it does not have the description of
every single thing implemented;

b) search directly into the source code, using "grep -d recurse "Agent"" and
related methods.

 

Alternative 1

Using the otcl MASH object inspector (installation described here), this
task is made trivial; one just has to check the otcl classes under "Agent".

For this, simply create a MashInspector object, and check the class named
"Class". On the instances column you'll check all the NS2 classes, which in
my version of NS are 595 of them. 

Thus, for the TCP variants are present in Agent/TCP/*.   (screenshot)

 

Alternative 2

An alternative would be to simply use the "info" introspection functions of
NS2. 

Eg,  Agent info subclass

However, note that this will only give you the first level of subclasses
under Agent/*. Thus, Agent/TCP/NewReno and its other friends will NOT
appear. 

 

Alternative 3

For addressing this, one can use the "subclass" method that I propose in
ns2_shared_procs.tcl, and is explained below. 

Eg. Agent subclass

This results in this complete list of Agent subclasses.

Hi, all

Hope this be useful for you.
The link for this
http://www.cse.msu.edu/~wangbo1/nshowto5.html


This simple example shows how to access the AODV routing agent of other
nodes. Use the following code in aodv.cc. This method can also be used to
access other objects such as mobilenode, etc.

AODV* aodvagent;

// set i to be the node id

char command[256];
sprintf(command, "foreach aodvagent [Agent/AODV info instances]\
{\nif { [$aodvagent id] == %d} {\nset i $aodvagent}}\nset t $i\n", i);

Tcl& tcl = Tcl::instance();
tcl.eval(command);
const char* ref = tcl.result();

aodvagent = (AODV*)tcl.lookup(ref);

These are some nice how-tos!


> This simple example shows how to access the AODV routing agent of other
> nodes. Use the following code in aodv.cc. This method can also be used to
> access other objects such as mobilenode, etc.
> 
> AODV* aodvagent;
> 
> // set i to be the node id
> 
> char command[256];
> sprintf(command, "foreach aodvagent [Agent/AODV info instances]\
> {\nif { [$aodvagent id] == %d} {\nset i $aodvagent}}\nset t $i\n", i);
> 
> Tcl& tcl = Tcl::instance();
> tcl.eval(command);
> const char* ref = tcl.result();
> 
> aodvagent = (AODV*)tcl.lookup(ref);

For tutorial purposes, let me explain what this code does, as it is a common
example of C++ / oTCL integration:

- suppose  i == 99
- in C++, a script is prepared to run, where the c++ variable id is inserted
in the "%d". Thus, the script results as this (comments are mine):

// cycle through all AODV nodes 
foreach aodvagent [Agent/AODV info instances]

	// if the current node has the id we want, save it 
	if { [$aodvagent id] ==  99 } {
		set i $aodvagent}
	}

	// dummy set, to make the function return the value $i. 
	// could also been just "return $i"
	set t $i
}

- in C++, the tcl.eval command executes the script
- the result of it saved in tcl.result() (eg, the otcl object _oXX that
we're looking for)
- converts the _oXX otcl object to c++ object with tcl.lookup()

This will only work when you install that extension correctly

Hi everyone!

i am trying to simulate CBQ for two class, everything looks fine but when i
try to run it i got error message like: unknown-flow from $node to $sink
with $flow-id. The exact error message is as:

Hi,there,
Maybe you can try to make those classes,Stuffs,Graduate etc. to be global 
and see if it works.The error usually happens when the classes are not well 
binded with fid_.
Hope it helps.


Thanks

Message-ID: <2b2e0d2c0512031321k9f1454fkc3e33507b3ab6a3e@mail.gmail.com>

the number of CTS comes out to be higher than RTS with multiple

any idea?
i am just maintaining  different counts for all packet types
in a simple 10 node scenario.
with shadowing propagation model.

Subject: [ns] binding flows for cbr traffic
Message-ID: <4ebe78a30512031342h2a319feaqb67f0d3747bddb24@mail.gmail.com>

Hi ns-users

I am using mns for binding traffic from two different sources in two
different paths
There is a very simple network with only 3 LSR nodes and hence only
two different paths...i set up one each for the two different traffic
sources
the code runs fine with no errors...the ldp mapping etc messages are
exchanged properly for the two different  routes and the confirmation
of the setup of the two LSps is also displayed in the shell terminal
but the traffic never floes in the 2nd lspid...that is the circuitous
route...

1)lspid 1500 is LSR6_LSR7 and flowid 100---the shorter route through
whihc traffic always keeps flowing--this er-lsp was set up at 0.2s
2)the other LSP is 6_8_7 with lspid 1600 and flowid 200---the longer
route through which traffic never flows--this er-lsp was setup at 0.3
s
the flows were bounded at 0.4s ...both the traffic sources were
sstarted and stopped at 1s and 5s respectively

cbr0 was meant to use the shorter path and cbr1 the longer path...I ma
not able to figure out the reason y no traffic would flow through lsp
1600.....do we haver to specifically bind a traffic source with each
of the lspids....but while binding flows,i have specified a different
destanation for each of the lsps....isnt that enuf....what shud i do
to bind the traffic source to a particular er-lsp

the code does not give me an error but the traffic doesnot get bound
to two different paths...plz help me out in this...

any pointers wud be greatly appreciated

Hi,
Does anyone has any idea whether FullTcpAgent works properly in Ns-2.29. I
am using Agent/TCP/FullTcp/Sack but it seems to be not working.
Anyone has any experience with working with FullTcpAgent in Ns-2.
Any suggestion or advice will be well appreciated.

Hi,

It seems there's a problem with broadcasting in ns. There's a thread
about this topic and a solution in the mailing list archives.

For me, broadcast works correctly if I set the ttl_ value as
(2*nb_hop). nb_hop being the number of hop I want to broadcast to. So
for your case, if you want broadcasts to be received by jsut 1 hop
neighbors, you can try putting ttl as 2.

Hope this helps.
Bye.

Subject: [ns] [NS2 problems] communication in wireless lan
Message-ID: <43931C95.7060204@gmail.com>

Hello,

I am working on a simulation of  wireless lan. The subject of my project 
is about the communication between a node and his neighbors.
The problem is that I don't know how to send a message (for example a 
char* "Hello") to a node and then make this node answer by an other 
message (char* "ACK" for example).

The only thing I have seen in the simulation of communication is just 
about sending packets and not about "messages" and the way to react when 
a node receive a message.

Thanks for your attention,

Olivier.

Thanks Huang for your reply

I tried by declaring all the cbq class as global but the problem is not
solve.
I'm getting same messages. I've gone through list, i found that for tcp
connection
reverse link also need to define flow id so that the acknowledge packets
from tcp sink
reaches the appropriate souce. But i'm not getting how to do that ?


Thanks Open

Subject: [ns] zrp and ns-2
Message-ID: <439355B0.4090407@daimi.au.dk>

I would like to do some simulation with ns-2 and the zrp-protocol, but I 
can not find a implementation of zrp that works. I have found to 
different implementations.

The first implementation is from this home:  
http://www.geocities.com/robin_poss/zrp.html.

I have compiled with ns-2 2.1b6, but the simulations end with this error 
message : "Scheduler: Event UID not valid".

The other implementation I got from:
http://people.ece.cornell.edu/~haas/wnl/Software/zrp/ns2/

I have compiled it with ns-2 2.1b9, and I get a segmentation fault in 
Packet::access everytime I run an simulation with zrp.

Is it possible to do simulations with ns-2 and zrp?

Hi all,

Can any body explain me ...what is the difference between two
commands...

 

set opt(chan)           Channel/WirelessChannel    ;# channel type

 
set val(chan)         Channel/WirelessChannel  ;# channel type
 
Thanks

There is no difference, it's just a variable.

Whichever you choose, just use that one when
you define the channel

set chan_1_ [new $val(chan)]
or 
set chan_1_ [new $opt(chan)]

Subject: [ns] how to connect a wpan node to a wlan node
Message-ID: <e8604ae30512041833h43cb6039m4d11422f5bd142f@mail.gmail.com>

Hi, all,

I have made a script that contains 2 wlan nodes and 2 wpan nodes (one PAN
coordinator and one device) .

I need connect the wpan node to wlan node somehow, so packets can be
forwarded amound nodes.

I tried TCP connection, but it doesn't work...I know this is silly.

What is the correct way of doing this?  Can anybody give me some advice?
Thanks!

Vince

My code is attached here, I am running NS2.28 on Debian Linux

If you dont care about the performance of the reverse link,you can simply 
declear the link node(3)-->node(2) as simplex-link CBQ while the reverse 
link as simplex-link DropTail.Or you can also declear the reverse link as 
simplex-link CBQ and repeat the cbq link construction.
Hope this helps.

Hello everybody,

I found that PHY and MAC layers of IEEE 802.15.4 is implemented in ns-2 (v.28 and above). However, it is not documented in the ns-manual. I found it under this link (ZigBee Routing):

http://ees2cy.engr.ccny.cuny.edu/zheng/pub/

Does anyone know any other documentation or examples on how to use ZigBee Routing and 802.15.4 MAC / PHY layers in ns-2? 
I appreciate any help in advance.

Yours,

Yes, that?s exactly that.
However, recently I've discovered that you can do it in a much simpler way.


Just check my page http://inesc-0.tagus.ist.utl.pt/~pmsrve/ns2/ns2_haddr_tips.html

And use 
"choose_simple_hier_parameters 5 5 5"

As with every contributed module, these will only work "out of the box"
without any modifications if you use the exact same version of NS2 that the
original author used.

Go and ask the author which was the exact version he used, and if it was a
CVS snapshot, then request a complete .tar.gz of its NS tree.

Things just don't work that way in networking protocols.
You have to define a header of your own , with a certain integer code in it.
Code = 1  === hello
Code = 2  === ack

Etc

For and study this part of the tutorial some times over before trying to do
your work.

Dear all,

I am developing a Zigbee NW layer over 802.15.4 MAC.
I want to use the NS-2 simulator to test my code.
Does NS-2 provides any C/C++ API to call MAC layer primitives from my NW
layer?.

Can any one know any reference source code for Zigbee NW layer?

Thanks in advance,
Regards,
Ranya

Hello,
Can someone tell me where NS2 works out delays when transmitting
wireless packets. I'm looking for propagation delay, transmission delay

Hi,

I have to count the number of packets collision at mac level and the number

can anyone suggest me how to analize the traces file to reach this purpose?

Subject: [ns] binding flows for cbr traffic--please help
Message-ID: <4ebe78a30512051505v1601a06cn3779cbf81964af76@mail.gmail.com>

Hi ns-users

I have posted this mail so many times without any reply.I really need
help with this.So if someone knows the answer,please respond
I am using mns for binding traffic from two different sources in two
different paths There is a very simple network with only 3 LSR nodes
and hence only  two different paths...i set up one each for the two
different traffic
sources the code runs fine with no errors...the ldp mapping etc messages are
exchanged properly for the two different  routes and the confirmation
of the setup of the two LSps is also displayed in the shell terminal
but the traffic never floes in the 2nd lspid  which  is the circuitous
route...

1)lspid 1500 is LSR6_LSR7 and flowid 100---the shorter route through
whihc traffic always keeps flowing--this er-lsp was set up at 0.2s
2)the other LSP is 6_8_7 with lspid 1600 and flowid 200---the longer
route through which traffic never flows--this er-lsp was setup at 0.3
s
the flows were bounded at 0.4s ...both the traffic sources were
sstarted and stopped at 1s and 5s respectively

cbr0 was meant to use the shorter path and cbr1 the longer path...I ma
not able to figure out the reason y no traffic would flow through lsp
1600.....do we haver to specifically bind a traffic source with each
of the lspids....but while binding flows,i have specified a different
destanation for each of the lsps....isnt that enuf....what shud i do
to bind the traffic source to a particular er-lsp

the code does not give me an error but the traffic doesnot get bound
to two different paths...plz help me out in this...

any pointers wud be greatly appreciated

THE OUTPUT IS:

1.024292 nodeid=6 : lspid=1500

THOUGH THE LSP IS CREATED,THE TRAFFIC NEVER FLOWS IN THE LONGER
PATH....Y IS THIS?

thanks a lot in advance

Subject: [ns] How much bandwidth to simulate bottleneck
Message-ID: <20051206002132.73183.qmail@web30803.mail.mud.yahoo.com>




 Hi ns users,
 
 I would like to how much bandwidth should i allocate
 to create a bottle neck between nodes. Is it correct
 to allocate bandwidth less than the total bytes
 transmitted?
 
 For example:
 
 1. CBR - UDP source = 50bytes per second
 2. Exponential - UDP soruce = 40 bytes per second
 
So I should allocate 50 bytes of bandwidth to create
 the bottleneck in the link.
 
 Please advise.
 
 Thank you very much,

Thanks Huang,
It solved my porblem.

  But this is not working. The error which i get is:

  So is there any thing wrong which i had done or may be there is error in my script.
  I also attached my script.

Don't call the produce method in the simulation init.
Use "ns at XXX "$ftp1 produce""
Or just "ftp1 start"

Subject: [ns] Help!!! Urgent!!! regarding broadcast
Message-ID: <4395B91D.5050202@cs.wisc.edu>

Hi,
 I am trying to implement a RFID protocol on NS2. I want to make a
 wireless node broadcast packets are regular intervals of time. How do i achieve
 this? Also i would like to disable the routing. So I am using a Dumb
 Agent for routing and to disable RTS/CTS i set the RTS Threshold to 3000. When
 i do this and run my TCL script, i get into a infinite loop(probably a
 recursive call) at classifier::recv. I set the ip address to the
 IP_BROADCAST and the ip source and destination port to 255. (I am doing
 all this in an Agent which lies at the same layer as UDP). Can u help me
 in this regard. Any help would be appreciated. Please reply as soon as
 possible.
 Thanks,
 Arini Balakrishnan

http://www.catb.org/~esr/faqs/smart-questions.html#urgent


a) setup a periodic timer
b) send a broadcast message as a beacon

check mip.cc for doing this. The Mobile Agents functionality do just that.

Subject: [ns] use of dmux_->recv(p, 0.0)
Message-ID: <4395C420.7060005@smileyfish.co.uk>

Hi All,

I apologise if my query has already been posted before, but could
somebody please help me to understand how the PortClassifier works?

I have recently found the following tutorials on how to compile
customised Routing Agent.

http://masimum.dif.um.es/nsrt-howto/pdf/nsrt-howto.pdf
http://www.cs.mtu.edu/~spark/mobile/mobile05/SkeletonForImplementingRAlg.pdf

As I try to compile the example codes in NS2 ver2.29 (after correct lots
of syntax errors), there is only one last compilation error which I
could not solve. It's shown below, and a suggestion was given.

routing/routing.cc:241: error: no matching function for call to
?PortClassifier::recv(Packet*&, double)?
./classifier/classifier.h:60: note: candidates are: virtual void
Classifier::recv(Packet*, Handler*)

So I went back to check both tutorials, and line 241 of routing.cc is
written as
dmux_->recv(p, 0.0);

After looking through classifer/classfier-port.h,
classifier/classifier-port.cc, classifier/classifier.h, and
classifier/classifier.cc, I couldn't understand why the tutorials were
written as what them were (though these tutorials were done in ns2 ver2.27).

I have also digged up NS2 ver2.27 to check on the classifiers, but they
are the same as the ones in ver2.29.

If anyone knows the answer to this, please let me know. Thanks very much
in advance.

Hi,

I`m trying to simulate a network flow control, like 802.3x.
Is there an implementation of it on ns?

Also, I`ve tryied to set the `blocked_` flag of a queue to false, but I
got an "Scheduler: Event UID not valid!" error. Is this the correct way to
pause dequeing? If not, is the there another way to do this?


Thanks in advance,

I've foud the solution to this problem: it can be solved downgrading
binutils from the cvs version (default in sid) to 2.16.1-2.

I hope this can help someone with the same problem.

Message-ID: <6617065e0512062356w7d24054doa4fb2f97128f5c46@mail.gmail.com>

Hello everyone,

Most of the wireless sensor network papers that I have studied have used

0.66 W for transmission
.0395W for reception
and 0.035 W for idle energy consumtion

>From where did these values came from and What if I want to change them,
what other parameters I will have to change....

Are these values related to the Pt and Pr parameters ?????

Any comments, help

umer.

Dear Vince, Dear Ramya,

Thanks for your reply.
In fact I am interested in the implementation of 802.15.4a in ns-2. Since Zigbee routing are based on 802.15.4, I thought that their code may be useful for me, especially that in the physical layer. I want to implement a new propagation model for the alternative PHY layer of 802.15.4a based on ultra wide band (UWB) in ns-2, since the radio propagation models implemented in ns2 sofar do not reflect the effects of UWB in the PHY layer.
To do so, I will use the following papers: "IEEE 802.15.4a channel model - final report" and " Conditional Bit Error Rate for Impulse Radio UWB channel with interfering Users." However, until now I do not know which files should I change and modify to add this new propagation model. 
I welcome any suggestions and hints!!!!

Yours,
samer Bali

  Hi,

  You can find the example codes under ./wpan/demo/ directory. And the introductory pdf file in the package is the manual...

  I am a ms student, and I am also working on the Zigbee NS2 simulation, so we may exchage ideas on it. I have just made a tcl script, I believe you have seen it in the same digest mail.

Hi

Has anybody tried to use a ns-2 simulator for Real-Time Network
Emulation with real-world IP-packets? Are there some extensions for
ns-2 to do that?
It's very interesting to see the perfomance test results.

I know, that there are some extension for RT Simulation, but i have
never seen even tries to make an Emulation using ns-2.

Thank you

Does anyone do the same thing with this??

That's because I manna run simulation on ns2 but no correct code for

If you see the trace file,
the lines that start with "D" (for drop)  as the event tells
you the packet that has been dropped.

The fifth field contains the reason for drop.
If it is "COL" it means that it was a collision.
Count all of them.

Subject: [ns] Getting information about every reachable node
Message-ID: <43989738.3070204@gmx.de>

Hi,

I am a new user of ns-2 (version 2.29) and hope you can help me.
Actually I am implementing (C++) a new application which should use dsdv as
rounting agent.
As usual my application derives from Application and the used protocol is
derived from UDP (it was necessary to extend UDP to send some data in the
payload).
It is necessary that this application (this application is running on every
node) gets access to information about every node (who is reachable in the
partitioned network, next hop, position information, routing table,...).
Furthermore it is necessary that connections between nodes (sender and
receiver) were set up dynamically (in the C++ Implementation) and not
previously because the decision for the destination node, which node shall
get the data depends on the node-movement and is done during simualtion
time.
I have some problems to find the classes/objects I have to use to get these
information (including GOD). If I am using god (God::instance()), I am able
to get access to every node in the network and can get position information
of them. But if I am trying to call ComputeRoute() or other functions
(floyd_warshall, ..) using the god instance I get a segfault. Calling
IsReachable (i,j) returns for every node true and the NextHop(i,j) is always
0 (I guess because the array is initialized with 0).
Using Simulator::instance() I was not able to get access to infomation I
needed (but perhaps I have overseen some attributes).
I was already searching (but unfortunately not successfull) in other classes
for RountingLists*, attributes or anything to which I can get access and
which can provide me with the needed information therefore I am able to make
routing decision.
Even I don't really understand the "bridge" between dsdv and the routing
table that has to be used, because I could neither find a "general object
(like a global RountingModule)" which I would be able to cast, nor the
routingTable which will be created by the chosen routing protocol.

I hope somebody can help me, because I tried already for several hours to
take a look in the source-code of the ns-core, but I was not able to get my
needed information.

Best regards,
Fabian

Message-ID: <B689ACAE7DCF7F4BA933EF549070994C018DE4B2@dlee07.ent.ti.com>

Hi,
 
We are modeling a MAC protocol for a wireless base station (BS)
communicating with numerous mobile stations (MS). The wireless physical
layer is abstracted by the Ethernet physical layer (i.e. all over the
air transmissions are modeled encapsulated in Ethernet frames).  The BS
application acts as a router/gateway: picks up IP packets, decides if
each packet is meant for a MS or the internet.  The BS application
schedules, fragments/re-assembles packets as necessary (based on the MAC
protocol we model) before sending (over Ethernet) in the downlink
direction to the MS or in the upstream direction to the internet. Our
purpose is quick/cheap initial testing/debugging of the real-world MS
implementation (FPGA-based, embedded OS etc) with the emulated BS as
accurately as possible.
 
We use the real time scheduler in ns-2.29 over a linux 2.6.11 (Fedora
Core 4) kernel and a standard 2.4 GHz Pentium 4 desktop.
 
With this setup, we see a (95%-ile) +-1 ms error in the timing for data
that arrives (from the BS) at the lab-test MS.  Since the events we are
interested in are on the order of 5 or 10 ms, for our application we can
tolerate occasional +-1 ms timing errors.
 
Over linux 2.4.20-6 (Red Hat 9) we measured this timing error to be on
the order of 10 ms.  2.6.11 did a great job of reducing the kernel
time-slice duration along with major changes to the kernel scheduler and
that is very clearly visible in our work.
 
One thing I have not been able to get a clear understanding for, is the
usage of the "slop-factor" that ns provides.  I can't seem to play with
it to improve the real-time accuracy any better than +-1 ms.  Makes
sense if the kernel time-slice is 2 ms (500 HZ jiffy), I think.  Perhaps
someone on this list has better experience with this.  
 
Regards,
Manish.

I want to simulate droping packets.
How a peer can drop data packets on ad hoc networks i use AODV routing 
protocol and TCP trafic
thanks

Hi sana,

you should read the section about error model in the ns2 manual. However, here 
is an example of how you can simulate frame errors in ns2:

?$ns node-config -adhocRouting $val(rp) \
? ? ? ? ? ? ? ? ? ? ? ? ?-llType $val(ll) \
? ? ? ? ? ? ? ? ? ? ? ? ?-macType $val(mac) \
? ? ? ? ? ? ? ? ? ? ? ? ?-ifqType $val(ifq) \
? ? ? ? ? ? ? ? ? ? ? ? ?-ifqLen $val(ifqlen) \
? ? ? ? ? ? ? ? ? ? ? ? ?-antType $val(ant) \
? ? ? ? ? ? ? ? ? ? ? ? ?-propType $val(prop) \
? ? ? ? ? ? ? ? ? ? ? ? ?-phyType $val(netif) \
? ? ? ? ? ? ? ? ? ? ? ? ?-channelType $val(chan) \
? ? ? ? ? ? ? ? ? ? ? ? ?-topoInstance $topo \
? ? ? ? ? ? ? ? ? ? ? ? ?-agentTrace OFF \
? ? ? ? ? ? ? ? ? ? ? ? ?-routerTrace ON \
? ? ? ? ? ? ? ? ? ? ? ? ?-macTrace ON \
? ? ? ? ? ? ? ? ? ? ? ? ?-movementTrace ON \
? ? ? ? ? ? ? ? ? ? ? ? ?-IncomingErrProc UniformErr

proc UniformErr {} {
set err [new ErrorModel]
$err unit packet
$err set rate_ 0.02
return $err
}

I'm also interesed in the error simulation, so if you find some other way to 
make it, write to the mailing list please :).

bye

Hi All, 
   
 I'd like to simulate three ad hoc multicast protocols : MAODV, ODMRP 
and ADMRP
   
 I found NS-2.1b8 support ODMRP and ADMRP and also MAODV have already 
implemented on NS-2.26 ... 
 any suggestion, which version of NS2 is better to simulate all these three protocols?

should i use different version of NS2 then ?
   
 thanks

Hi,

I am using the 802_15_3 MAC developed by Intel in 2002.
I am trying to write a script to establish transactions between nodes using
the 802_15_3 mac, but in vain.
I don't understand something in the mac::command method: why when there are
6 arguments (argc=6), the last argument in the list is not parsed; there is
no argv[5]?

Thank you for any help.

Subject: [ns] Problem with protocol NOAH for static multihop
Message-ID: <BAY102-F31C77C64F2292EE167A33CE2450@phx.gbl>

Hi,

I'm using the protocol Noah to simulate a wireless scenario composed by a 
singol line of nodes (called "hop_(i)" ) and other nodes that are not 
involved in the static routing...
The total number of nodes of the topology is $val(nn) = #hop_(i) + #nodes

I uses the following code to implement the multihop routing between the 
nodes "hop_(i)" without involved the others nodes:

#Noah static multihop
	for {set j 0} {$j < $num_hop } {incr j} {
    	set cmd "[$hop_($j) set ragent_] routing $num_hop"
    	for {set to 0} {$to < $num_hop} {incr to} {
		if {$to < $j} {
	    	set hop [expr $j - 1]
		} elseif {$to > $j} {
	    	set hop [expr $j + 1]
		} else {
	    	set hop $j
		}
		set cmd "$cmd $to $hop"
    	}
    	eval $cmd
	}

where $num_hop is the number of $hop_(i) and i uses it instead of $val(nn)

Unfortunately the simulation fails due to the following error :
" no route known"

Can someone explain me why??

Thanks,

Dario

Looks a good starting point, but:

a) I think NOAH doesn't support multihop routing; its only a way of moving
the packets to/from Mobile nodes / basestations.
For that your need to change C++ noah.cc

b) give examples of the TCL commands this code generates;
c) where is the "routing" command? Its not in NOAH. Is it inherited? If yes,
is it considered in NOAH? I think not.

d) use DDD to debug what happens in the first packet transmission.

1) from http://www.isi.edu/nsnam/ns/

Read this first:
While we have considerable confidence in ns, ns is not a polished and
finished product, but the result of an on-going effort of research and
development. In particular, bugs in the software are still being discovered
and corrected. Users of ns are responsible for verifying for themselves that
their simulations are not invalidated by bugs. We are working to help the
user with this by significantly expanding and automating the validation
tests and demos. 
Similarly, users are responsible for verifying for themselves that their
simulations are not invalidated because the model implemented in the
simulator is not the model that they were expecting. The ongoing Ns Manual
should help in this process.


Thus:
a) check that core components are OK by running validation tests
b) auto-validate your own work by careful, step by step verifications of
trace files and at run time with DDD

You can limit the transmission power of the MNs and BS.
These functions were derived from CIMS code, on the CIP example.

Basically, calculate the power for an encompassing rectangle with a certain
overlap with

	HalfCellCoverage { x1 y1 x2 y2 overlap } {
then use the value here
	$ns node-config -rxPower $power -txPower $power


PS: don't ask too many questions about this one :-) - its old code, but it
works!

I am running a Wired-cum-Wireless script from Marc Greis examples and trying
to analyse ".tr" file. As he mentioned in his notes (for file:
~ns-2.28/ns-tutorial/examples/wireless2.tcl ) I should be able to see "WL"
for a wireless traces. But when I analyze ".tr" I dont see any. I wonder if
the option was disabled in ns2 or the wireless transmission is analyzed by
diectly looking at nodes in trace files.

What's the situation actually..? :-(

a) These type things are normal in NS - things are so large that its very
difficult to have everything tidy. Also, persons who make modules doesn't
take care to maintain them


b) I don't use 802.15.3.
c) best place to learn TCL scripts is to check the simplest in 

/tcl/test - validation tests - 100% guaranteed to work.
/tcl/ex   - examples - might be outdated

The standard ns-2 2.29 does not contain our own improvements. These will 
highly increase the timing accuracy at the cost of a higher CPU load. You 
will get the best results by using a 2-CPU or dual-core-CPU as we devide the 
ns-2 into a low and a high priority process (one for the simulation and one 
for logging, disk access etc.). A detailed description of the improvements 
can be found in the papers on our web page. The patch should work with ns-2 
2.29. If you try it, please give us a short feedback about the accuracy that 
you experience. 

Best regards, 
Daniel.

Short Notice to NS2 beginners: 
------------------------------
Congratulations! This an excellent post, written exactly as it is suggested
in http://www.catb.org/~esr/faqs/smart-questions.html



-------
Try

	dmux_->recv(p, 0);
or, the same thing but more clear,
	dmux_->recv(p, NULL);

or, if the current function has an "handler" parameter, just pass it away
	dmux_->recv(p, h);


This will call you the recv function with a null handler (eg, "0"). 
I've seen this kind of function callings with absent callback handlers many
times before. 

(It looks to me as a simple typo, which forced the compiler to search for a
corresponding function with a floating number argument)

Finally, you are welcome to post the corrected examples to NS2.29 in
somewhere like a web page, or send it to the original author.

I read at the site  http://icapeople.epfl.ch/widmer/uwb/ns-2/noah/
that Noah supports multihop routing and i apply the example code to my 
simulation according to the necessity of only 1 comunication between the 
first node of the line and the last.

but the source node (the first of the line) fails to send all packets to the 
last node of the line because it don't known the route for the 
destination...

Unfortunately even this new code don't work

for {set j 0} {$j < $num_hop } {incr j} {
    	set cmd "[$hop_($j) set ragent_] routing 1"
		if {$j==($num_hop-1)} {
		set hop $j
		} else {
		set hop [expr $j + 1]
		}
		set cmd "$cmd $num_hop-1 $hop"
		eval $cmd
	}

I hope that you can give me another advice.
Thanks

OK, this new version of NOAH is supposed to have multihop functionality 
(I'm using the original, older version)

You I'll have to check the noah.cc and check what the "routing" command
located there in the "command()" function does, and figure out the proper
way to call this functionality.

Hi,everyone,


	I had installed ns-2.1b6 successfully, but after i typed "make
mobiwan" to install it,  I got the following error as shown below.., can any
mobiwan experts here give me some advice? 

Thank you very much..

What kind of gcc compiler do you use?
For ns-2.28 you might have a problem with gcc-3.4

>From your mail, since you issue ./install, you're using
NS-Allinone 2.28, not plain NS-2.28.

Did you check the NS-Allinone 2.28 bug
fixes<http://www.isi.edu/nsnam/ns/ns-problems.html#ns-allinone-2.28>
?
There is one that may cause build failing of your code.

Also, you can always build it from the pieces, installing
NS-2.29. I have Debian 3.1 and it runs smoothly (but I think
that a change in OS might be out of the question
for you right now :-) ).

Hope that helped

Message-ID: <3fb281ef0512100329p7f6223b6o96f0a8c3bc6f22a5@mail.gmail.com>

Dear all,
I want to know the speed of a mobile node when in its routing protocol such
as AODV.
I know that in "MobileNode" class, the "speed()" member method is defined to
access a node speed. But, I don't know exactly how should I call it.
I have included #include <mobilenode.h>, but  I could not access to the
""speed" method. what should I do more?

Regards,Shahram Mohrehkesh

Subject: [ns]  LAN : one node part of two different LANs
Message-ID: <002401c5fd7d$208343e0$a836000a@ronny>


I'm attempting to create the following simple topology, while using hierarchical addressing :


LAN 1 ("0.0.0") ---------- NODE ---------- LAN 2 ("0.1.0")

The node in the middle can be seen as a Router/Switch in real life.
But in ns, as far as I am aware, you can only give one address to a node.
Because if you attempt to join node ("0.1.1") to LAN2 this will be fine,
but ("0.0.1") will refuse, giving the next error message :
       
    Segmentation Fault (core dumped)

So how do you solve this ? Can anyone help me, or tell me this is impossible ?

I think the solution might be found in "Node instproc add-neighbor{}".

Thank you very much for the trouble !!

Sincerely,

Subject: [ns]  LAN : positioning in NAM
Message-ID: <001301c5fd82$ea8381f0$a836000a@ronny>

Has anyone ever tried this topology (see my last question)

LAN  ---------- NODE ---------- LAN 2


I used the command "Simulator instproc newLan" to create both lans.

When looking at this topology in NAM, the 2 lans are positioned one on top
of the other.
This is very confusing to look at.

How can I position a lan in nam ?
Is there something like "duplex-link-op" for layout ?
Why is there sometimes a "re-layout" button in NAM and sometimes not, in my
case NOT ?


Thank you very much for your time!!

Subject: [ns] [NS]  Problem to access the neighbors list of mobile nodes
Message-ID: <439B0902.6070403@gmail.com>

Hello,

I am working on a project about communication between  mobile nodes and 
I am nooby in tcl and NS2.
My first part is about sending packets to each nearly neighbors of a node.

I know that there is a variable "neighbors_" which contains the 
neighbors of each node but I cannot access these informations. First 
because I have some problems to access the list using tcl and second 
because The list seems to be empty when the topology of my network is 
created.

I  am using the AODV routing protocol which should update itself the 
variable of the neighbors but I don't know how access it.

Thanks a lot for help,

Olivier.


P.S : I am a French student,and I apologize for the mistakes in my English.

If you will see tcl-object.tcl in tclcl you will see this

# In ns, this error happens for several possible reasons:
#
#       1. you bound a variable in C but didn't initialize it in tcl
#               To fix:  put initialization code in tcl/lib/ns-default.tcl
#               (and make sure that this code ends up compiled into your
#               version of ns!)
#

This is the most common reason.
Just see that LanRouter::debug_  is defined in the ns-default.tcl.

Hi Oliver,

by default, in AODV, no Hello messages are sent, so it's probably that the 
neighbour list is not refresh. You can enable the use of Hello messages 
uncoment the MAC_LAYER, or something like that, define.

I'm using AODV in some project and I can acces to the nb_list withouth 
problems.

If you still cannot acces to it, send us details about your code or something.

Bye.

Message-ID: <3fb281ef0512110314g7d4db4c0o88267a8c51030cd@mail.gmail.com>

Dear All,

First, I want to have the (signal to noise ratio) SNR of a mobile node.
Is it calculated in NS? How it could be acceseed?

Second, what is the default value for the antenna range of mobile node? (I
think it is 250 meter, but I did not find it).
Where is it set? And, Where could I set it to another value?

You say after recompilation...
Did you make any changes to the main ns files?
So, that every time you try to execute ns with its
command it terminates with a runtime error?

Why did you need to recompile? What changes did you make,
or in any case, did you tamper with the ns files?

Subject: [ns] srtt_ problem !
Message-ID: <439D46DD.9020609@n2nsoft.com>

I have a problem using srtt_ parameter in ns2.
Here is a fragment of my tcl code :

/proc srtt {} {
    global NUM_TCP tcp total_srtt_sim srtt_flow
    set ns [Simulator instance]
    set time 1.0
    set now [$ns now]
    set total_srtt_inst 0
# srtt computation :
    for { set i 0 } { $i < $NUM_TCP } { incr i } {
        set smoothrtt [$tcp($i) set srtt_]
        #puts "srtt inst : $smoothrtt"
        set srtt_flow($i) [expr $srtt_flow($i) + $smoothrtt]
        set total_srtt_inst [expr $total_srtt_inst + $smoothrtt]        
           
    }
    set total_srtt_sim [expr $total_srtt_sim + $total_srtt_inst]
    #puts "total srtt : $total_srtt_sim"
       
    $ns at [expr $now+$time] "srtt"
}/



I set the delays over links while creating it to 200ms, so with the 
delay in the buffer, it should be at least 200ms. when i compute rtt 
using srtt_ as above, the mean is LESS than 200ms. How is this possible ?

Thanks a lot for any help.

I have recompiled ns, but the problem still exists.

Somebody had asked this problem before. There is not a good solution.
Could anyone help me?

the problem was that the tcpTick_ was not set by default at 0.1
it's strange, i had to set it manually, and put a granularity of 0.01 
for my srtt_ computation.

Subject: [ns] why packets are dropped without reason?
Message-ID: <200512121400.jBCE0Jc3028426@noya.bupt.edu.cn>

hi, everyone. when i ran the 802.11 based woreless scenarios i found there were always lots of dropped packets with no reason in the trace file. the number of such item sometimes was tremendous. does anyone know why this happens?

i have also tried the following scenarios: 3 node A, B and C lie linearly with distance 100 meters and transmission range 250 meters. A and C send packets to B at the same time. B recieved both packets and soon drop them without any reason. no collision occurs. it is so strange! i do not know whether this is a bug of NS-2. 

does anyone know why this happens?

Hello,

i'm working on the following problem : i'd like to simulate an application (middleware for mobile add-hoc networks) on ns, and this application changes the routing table dynamically.  Is it possible to modify the routing table 'from above' from the application ?  Does an agent have access to the routing tables of the nodes ?  
Thanks,

All the sent packets by a node are piped to the routing agent, wich is the 
layer that decides if it's neccesary discovering a route or not, or only 
route the packet by the correct node.
So, the app agent should be able to comunicate with the routing agent using 
messages.

In the other hand, you can execute routing agent Tcl commands from the app 
agent.

  This is Ronak Shah. I am working on Master Thesis at California State University, Los Angeles. I am working on Link State algorithm. I have tried really hard to install tcl-debugger to debug ns-2. I am using Red Hat Linux 9.0 and ns-2.29. 
   
  I have succeffully install ns2 and also enable the debug information in ns2.
   
  I have place tcl-debug parrallel to ns-2.29.
  (1) cd ns2.29
  (2) ./configure --enable-debug --with-tcldebug
  (3) make clean
  (4) make
  (5) make install
  (6) Add breakpoint "debug 1" into example3.tcl script file.
   
  Here is the output.

packets are never dropped without reason. could you give ur output? Also
check the range and topology could be interferece due to hidden node..??
good luck

Message-ID: <10885.1134437800@www16.gmx.net>

hi,

I am trying to get information of the routing table of each node (neighbor_
or (MobileNode) link_), but I always just get an empty list. Actually I am
using DSDV, and even if I set the position of the nodes manually very close
to each other or at the same place, these lists are still empty.
Below a part of my otcl script 


set opt(nn)             5                          ;# number of mobilenodes
set opt(rp)             DSDV                       ;# routing protocol

$ns_ node-config -adhocRouting $opt(rp) \
                 ........

set god_ [create-god $opt(nn)]

for {set i 0} {$i < $opt(nn) } {incr i} {
	set node_($i) [$ns_ node]	
	$node_($i) random-motion 0		;# disable random motion
	$node_($i) radius 200
	$god_ new_node $node_($i)
}
$god_ on

$node_(0) set X_ 380.0
$node_(0) set Y_ 390.0
$node_(0) set Z_ 0.0

$node_(1) set X_ 390.0
$node_(1) set Y_ 385.0
$node_(1) set Z_ 0.0

$node_(2) set X_ 400.0
$node_(2) set Y_ 400.0
$node_(2) set Z_ 0.0


The only information I can get about the network is via god, so the current
position of each node.


if ((num_nodes = God::instance()->getNum_nodes()) && (list_mobile_nodes =
God::instance()->getList())) {

But God tells me that every node in the network is reachable (even if I set
position far away ((0,0) and (500,500)) and tells me, that the next hop to
the destination will be done via node 0.

if (God::instance()->IsReachable(agent_->addr(), best_node->address())){
God::instance()->NextHop(best_node->address(),4)



I get for every node the message that there is no neighbor available.
Here is a part of my code. 


MobileNode *best_node;
best_node = list_mobile_nodes[i];
//best_node is MobileNode != NULL and I am able to get position information
here
if (best_node != NULL) {
	if (best_node->neighbor_list_ == NULL) 
std::cout << "**************There is no neighbor available for node "<<
best_node->address() <<"**************\n";
......


Please can anybody help and tell me what I am doing wrong, therefore I can
get access to the routing table of each node, because I need to know which
nodes are currently available in which partitioned network.

Thank you very much for help.

Fabian

Hi, 
I recently installed tcl-debug2.0 on my system. 
Maybe you should process as following:
1. install tcl , tk, and tcl-debug individually
 a)./configure, when you install tk and tcl-debug run ./configure --with-tcl=<path>
 b) make distclean
 c) make
 d) make install
2. in the directory of ns-2.29
 a)make clean
 b)./configure --enable-debug --with-tcl=<tcl path> --with-tk=<tk path> --with-tcldebug=<tcl-debug path>
 c)make
 I think uou need not type make install here.
 If you suffer any problem, refer to the README or configure files in the corresponding directories.
Good Luck
Wei Zhang

Subject: [ns] senario and traffic generation
Message-ID: <20051213130522.8zi61ddyqlwgko4k@webmail1.sjtu.edu.cn>

Dear all,

I use cbrgen.tcl to generate the traffic senario of wireless LAN simulation. I found that if I set the number of mobile nodes to N, the node number would be from 1 to N. I prefer a number sequence from 0 to N-1.
I looked the source code of cbrgen.tcl. I did understand the usage of random variable x. It is compared with 50 and 75, why?

I set two type of traffic cbr and tcp, and applied both senario in wireless1.tcl (in ns-tutorial/examples). When I use cbr generation file, the simulation is ok. while when I use tcp generation file, the segment fault message displayed. Would you like to explain me the reason?

Can I use cbrgen.tcl to generate simulation senario for ad hoc or wireless sensor network simulation? and use setdest to generate the topology structure for these simulation?

Thanks!

Wei

Message-ID: <d3b0adff0512130517s17a7c572p@mail.gmail.com>

Hello to all
   Is it possible to set an address to a node in NS. I did try like this
"$n0 set addr_ 10". But when i print the address i get the address of the
node as "0" and not "10". I know that the node address at the beginning is
"0" and for every node created it increases sequentially. But is it possible
to override  this address with a new address that we set.

Cordialement,
Sandoche BALAKRICHENAN.

Hello everybody,
I'm writing some applications on udp and tcp and I need to reference
TCL variables from C++ code, right now I'm using something like this:

tcl.evalf("[Simulator instance] connect $agent(%d) $agent(%d)",
myaddr_, dstaddr_);

it works but, as you can see, it's a bittle ugly as it forces to write
tcl script files using a specific syntax, so, is there a way to
reference agents, nodes and other applications as it is done with
[Simulator instance]?

Thanks a lot for any help
ciao

-----------------------------
Description:

Description of Problem:
with multiple drops in a window, Agent/TCP/Fack sends new data that exceeds the
+receiver's (or wnd_ or window_) buffer


How Easily Reproducible:
(e.g. every time, intermittent, once only, etc.)
every time

Steps to Reproduce:
(describe the minimal set of steps necessary to trigger the bug)
1.
2.
3.


Actual Results:
(describe what the application did after performing the above steps)
sends more new segments than receiver is ready to accept


Expected Results:
(describe what the application should have done, were the bug not present)
should not send new segments (see tcp-sack3.cc tests)


Additional Information:
(the following infomation is helpful to debug:
 1. simulation script, detailed output files, packet trace
 2. patch file if you modify some source code
 3. a backtrace from gdb if you get a segment fault
 If they are big files, PLEASE put them in your web space and
 include the URL here.)
I have the script at
  http://www.cs.utk.edu/~dunigan/fack3.tcl
and a plot of the offending behavior at
  http://www.cs.utk.edu/~dunigan/fack3.png


here is some trace info i added to tcp-fack.cc
thd recover 0 highest 98 wnd 20 tmit 118
thd recover 0 highest 99 wnd 20 tmit 119
thd recover 1 highest 99 wnd 20 tmit 120

thd recover 1 highest 119 wnd 20 tmit 129
thd recover 0 highest 120 wnd 20 tmit 130

tcp-fack.cc is sending data where snd.nxt is > highest_ack + wnd

the tcp-sack1.cc code has an if test to prevent this happening
 if (xmit_seqno == -1) {
  if ((!fastrecov_ && t_seqno_<=highest_ack_+win)||
   (fastrecov_ && t_seqno_<=highest_ack_+int(wnd_))) {

i argue that tcp-fack.cc needs such a test

Message-ID: <8372803c0512130840q7c3cf437r4fd04e7f9977cb3e@mail.gmail.com>

Since TCP Vegas builds on top of TCP Reno's congestion and retransmission
mechanisms
and since TCPSink Object is valid as a receiver for TCP Reno and TCP Tahoe
(NS-2 Manual
page 97), I think it could be "safe" to use a TCPSink Object as a receiver
for TCP/Vegas.

I've tried it in one simple simulation and it worked fine. It did not return
any errors
nor I noticed something odd with the results

Hope to have helped...

Hi everybody.

I am working with multihop wireless networks and I need to monitor the
length of the queue in each node. I wrote an awk script (below, i.e. for
monitoring the queue in node _2_):


BEGIN {ingresso=0;uscita=0;coda=0}
     {
     if ($1=="r"&&$3=="_2_"&&$4="RTR"&&$6="180"&&$7=="cbr")
{ingresso=ingresso+1}
     if ($1=="f"&&$3=="_2_"&&$4="RTR"&&$6="180"&&$7=="cbr")
{uscita=uscita+1;coda=ingresso-uscita;print "ingresso = ",ingresso, "uscita
=", uscita, "coda = ",coda}

In fact, although at a certain point of the simulation I experience an
increasement of the average delay, the output of the scripts - applied to

Can anybody suggest me a different approach to achieve my goal?

Thank you in advance...

	English
Message-ID: <BAY14-F19E4FB7720B304AB8EF836A4380@phx.gbl>

Sorry, I send again my mail ... I cut and pasted the original awk code 
without translating the names of the variables.


I am working with multihop wireless networks and I need to monitor the 
length of the queue in each node. I wrote an awk script (below, i.e. for 
monitoring the queue in node _2_):


BEGIN {pk_entering_node=0;pk_leaving_node=0;pk_in_queue=0}
     {
     if ($1=="r"&&$3=="_2_"&&$4="RTR"&&$6="180"&&$7=="cbr")
{pk_entering_node=pk_entering_node+1}
     if ($1=="f"&&$3=="_2_"&&$4="RTR"&&$6="180"&&$7=="cbr")
{pk_leaving_node=pk_leaving_node+1;pk_in_queue=pk_entering_node-pk_leaving_node;print 
"ingresso = ",ingresso, "pk_in_queue =", uscita, "pk_in_queue = 
",pk_in_queue}
     }
END {print "stop"}

Dear NS users

I am pleased to announce a new version of WFQ. Basically, it provides the
same functionality comparing to the previous version, but now it can applied
easily
to several versions NS-2. It has been tested with v2.27, v2.28, and v2.29.

Try gcc-2.95

Check

PS: on a related note, this idea also works backwards; If you are trying to
compile old code for old versions of NS (NS-1b6 and friends), You'll get a
much better chance if you use earlier versions of GCC, like gcc-2.95.

I've done steps like that previously, on the CIMS micro-mobility suite. 
Thus I suggest:

a) start using the module on the proper ns2 version until you can use all
parts of it
b) make modifications on C++ and TCL parts to learn the inside of the code;
c) learn to use diff and patch
d) make a diff between "original old ns verion" and "old ns version with
that module"
e) try to apply that patch to ns-2.29, and solve the inconsistencies that
appear
 
warning: this is a fairly amount of work!

Arrays are very tricky in tcl.
Try " $grade duplex-link $n($i,$j) $n($i,[expr $j+1]) 2Mb 10ms"
(note the added [] on the exprs)

5: The above, but modifying the NS2 simulator yourself.
When you are doing cutting edge research, that nobody did before, the only
solution is to model your own additions to NS2.
The first thing you should do is to locate a similar module that does
something that you want to do also. perhaps another ad-hoc routing protocol,
another QoS queue discipline, etc etc. Then you should clone the code, and
change ALL names of variables, TCL bindings (*), C++ classes, packet
headers, etc etc, to YOUR component name. When you do this you'll get a
working component that you can start to SLOWLY modify to make YOUR
algorithms and operations.
If you do this way, instead of simply start coding from scratch, you'll be
able to work with a working component, step by step, that you are able to
validate every day. The alternative way, you spend be months, or even more,
before the component worked for the first time.

Subject: [ns] how we can generate one common tr file for different
	protocols for wireless networks
In-Reply-To: <20051214122319.14876.qmail@web8604.mail.in.yahoo.com>
Message-ID: <002101c600b6$e316fbe0$172914ac@Estrela>



a) Manually run the simulation and give different names to the .tr files
b) process the .tr files with AWK or tracegraph (with scrtiping ) and
collect the results per protocol
c) compare the protocols in a common graph (use "xgraph proto1 proto2 ...",
or gnuplot with "multiplot")

d) later, make all these steps automatic

Hi all,

my problem is the following:

I am conducting some adaptions within the Droptail-Queue-algorithm.

Doe anyone know how to find out the id of the node the queue
is attached to?


Thanks a lot,

Message-ID: <1504.210.212.228.103.1134625470.webmail@ebox.nitc.ac.in>

Hello everyone,
          I want to find out the total delay of the packet frome the time
it is generated to the time it is received correctly. We have an
option to find the mac delay. But is there an option for fing
the queuing delay? Can we find the time when the packet is
generated?
          One more question.. I compiled poisson patch. I got some
messages that some test results are not matching with the
reference output. Will there be any ambiguity in the delay
obtained in that case? Or is there any solution for that?
          Any help is appreciated.Thanks in advance..
Regards
Teena.

use grep to extract the necessary information from trace file....Usually
when the packet is generated, it will be sent from the application layer:
In the trace file, it would be something like:
s time _nodeid_ AGT .......

I think "time" field is what you need!!!

Subject: [ns] Classifier/Hier 'no target for slot 0' problem
Message-ID: <10924119.1134642771774.JavaMail.root@pswm4.cp.tin.it>

Hi,

we are trying to extend SCTP multihoming support to wireless 
channels,
so that a wireless node can have multiple interfaces and use 
SCTP as
a wired one. Changes to the code are needed, since there is no 
support
for multiple interfaces in mobilenodes right now.
We added such 
support by adding a couple of methods to ns-lib.tcl and
sctp.cc, but 
then we got the following error at the beginning of the simulation:

SORTING LISTS ...DONE!
--- Classfier::no-slot{} default handler 
(tcl/lib/ns-lib.tcl) ---
        _o201: no target for slot 0

offset
        0 shift
        2147483647 mask
        0 slots
---------- Finished standard no-slot{} default handler ----------

I 
read several mails on the archive about the 'no tartget for slot X' 
problem,
but *none* referred to the *Classifier/Hier* class. If I got 
it right from such mails,
the problem should stay in the wired nodes 
(W0, the intermediate router or
one of the BSs) of our topology 
(depicted next)

#                           BS0     
#        	
         ----0 )))) 0

#	                \     	     / 
#	
                 ----0 )))) 0   
#                          BS1

since 
mobilenodes do not use Classifiers.

Does anynoe has a clue on the 
possible cause of this error?

Thanks,

Hello Ns Users,

 

I need a mobile node with more than one interface in my simulation's
scenario. I am going to connect one MN via different interfaces to different
Base stations. Is there such a node or something like Mobile Router in NS-2?
Or do you have any idea to impalement a mobile node with this feature?

  

Thanks in advance for your answers,

Subject: [ns] Mobile agent - error in on/off command
Message-ID: <43A16C75.5090707@fly.ath.cx>


Hello all,

I'm simulating mobile ad hoc routing protocols, and I want
to turn node radio transmission 'on' and 'off' in my mobility scenery.
To do that I'm using the on/off command of mobile nodes...

But, in my first try, the NS-2 (version 2.28 or 2.29) exited with this 
message:

<snipet>
Starting Simulation...
ns: _o18 reset-state:
   (_o18 cmd line 1)
   invoked from within
"_o18 cmd reset-state"
   invoked from within
"catch "$self cmd $args" ret"
   invoked from within
...
<snipet>


Then, I removed the line 'tcl.evalf("%s reset-state", str);' in the 
mobilenode.cc file, and the simulation worked great.
I've searched for reset-state command, but and I found nothing.

Is this a bug, or I'm doing something wrong?
Does anybody knows a better way to put a node to sleep (turn radio off)?

Thanks for your attention,
Julian

You can control the congestion window (the number of packets sent out for each RTT) using the opencwnd() function. Standard AIMD is defined in case 1 while case 7 is empty for experimental purposes. You can define your increase algorithm here.

Hi Marco,

I got the same problem a few days ago. My topology was wired source
nodes directly connected to a base station which links the traffic to
some wireless destination nodes. I read in the mailing list as this was
a topology problem. The error disappeared when I connected the wired
source nodes first to another wired node and than this wired node to the
base station. Maybe you can figure out something from this behavior, and
apply to your problem.

Inanc Inan

PS. Your topology figure is corrupted in the e-mail I received, that's
why I cannot comment on it.

the patch you've used has modified the NS2 core modules, and the standard
tests do not give the tried-and-tested results.

This means that results from that NS2-version  ___MAY___ not be accurate in
comparisation with unmodified NS2.

You should:
 - validate all steps that on work work;
 - try to understand why / what test results have changed, and 
	- either correct the new module for these results to be maintained
OR
	- prove that the new results are "more accurate"

Have you searched on the C++ implementation?
Check this:
http://inesc-0.tagus.ist.utl.pt/~pmsrve/ns2/ns2_debugging.html#_Toc122255044

and do "grep -d recurse reset-state *"

 
> Is this a bug, or I'm doing something wrong?
It seems that you are skipping a step, but the NS2 modules are robust engouh
to not need such reset

Subject: [ns] mac layer problem
Message-ID: <BAY17-F29927E91650EF5FC341D67DB3A0@phx.gbl>

hi,
i'm designing (coding + simulation) a new routing protocol for MANETs and 
the protocol i want to design, needs to store the power values of the 
neighbouring nodes in the mac-layer. To do so it needs to maintain a table 
of these values at MAC-layer.These values will be retrieved by the Network 
layer as and when reguired. i don't know much about MAC and how to create a 
table, store values in it and later on retrieve those values.
If anyone can guide me how to deal with MAC layer or provide a link to an 
online resource with the help of which i can learn this, i'll be very 
thankfull.

Thanking in advance and looking forward to your response.

Hi all,

I am new in NS-2.
Until now I used C++ and self-made event driven simulators for my
simulations.

My question is probably silly, but I am very interested whether there is
any implementation of ordinary Static Priority Queue in NS-2 simulator
(the best is more than two level of priorities)?

Do you know any clues?

Or, do I have to write my own PQ class and include it to NS-2?

I appreciate any information very much.

Hi

It seems that the basic scheduling framework of the NS-2 simulator does not
support it. However, this scheduling disciplines is available in the
DiffServ framework.

Message-ID: <4597b4d00512160532s55a9f20bu@mail.gmail.com>

Hi,all
I want generate Traffic from Tcpdump dump file.I have extracted two items:
time and packet length from Tcpdump dumpfile;
I have used Application/Traffic/Trace and UDP,I found UDP wasn't suitable,
because UDP agent didn't generate traffic in packet level just as Tcpdump
dumpfile record.The packet length changed,and sendtime was not the same as
Tcpdump dumpfile record.
now I want to simulate traffic in packet level just as the content of
TCPDUMP dumpfile.
how ? can you give me a tip? thanks!

Subject: [ns] Unexpected Wireless Throughput
Message-ID: <BAY101-F21F542CEC1569F4FBECD06D23A0@phx.gbl>

Dear all,

I have a question regarding the throughput of wireless networks.

I have made a simple wireless network (one wireless node connected to a
base station) and then analysed it using Tracegraph. However, I seem to
be observing lower throughputs than I was expecting (for example about
750Kbits/s when the distance is 2 metres). As most wireless cards are 11
or 54 Mbits/s I was expecting a higher throughput than this - especially
for such a small distance. Do people think this is an accurate figure or
have I overlooked something?

I would be most grateful for your advice.

Adam

  So I tryed with : ns exemple.tcl
  But it gives me the error
     "bach :ns:command not found"
   Where is the problem ,please help me !!!!!!!!!!!
  I found in the documentation that after installing ns2 we must :
   1)put the path to my ns executable into my path environnement 
   2)put the path to my ocl in my LD8LYBRARY8PATH environnement
   3)put the path to my tcl library into my tcl_library environnement.
   But I don't know how I  put the path to my ns executable into my path environnement ,
  and also the second and the third point.
  Please help me !!!!!!!!!!!!
  thanks .

Message-ID: <779DD7B0-6577-4DA7-8460-9F2631AF7BD7@wadh.ox.ac.uk>

Dear all,

I am comparing the performance of different ad hoc routing protocols
in ns-2. Simulations I have made work wine with AODV and DSDV
protocols however DSR seems to start ok and then at a strange time
will halt the simulation and display 'child killed: bus error'. This
is the error that I got using Mac OS X, when a friend tried the same
simulation using Windows it gave a  "Segmentation fault (core
dumped)" error.

Any help would be very gratefully received,
Many thanks,

Hello David,
  
  Try putting in your tcl script instead of
  
  set val(ifq)  Queue/DropTail/PriQueue 
  
set val(ifq)            CMUPriQueue
  
  I think this will solve your problem,

Hi,
To specify the communication range of wireless nodes, you should set
an appropriate value of the receiving threshold in the network
interface (in your tcl script), i.e

Phy/WirelessPhy set RXThresh_ <value>

A separate C program is provided at
~ns/indep-utils/propagation/threshold.cc to compute the receiving
threshold. You have to compile it, then you can use the executable to
compute the threshold as follows:

threshold -m <propagation-model> [other-options] distance

Ex:

threshold -m Shadowing -r 0.95 50.

Here the propagation model is Shadowing, the communication range is
set to 50m, and 0.95 is the rate of correctly received packets.

More details can be found in ns_manual.
I think the default value is 250m (ns 2.28)

Hope this helps.

Bye.

Message-ID: <20051218051339.EKVA3033.fep2.bj1860.net@buptc154154636>

Hello everyone!

I want to simulate how 802.11 RxTxTurnaroundTime affects the performance of
ad hoc networks.

I notice the code with ns-2.26 as follow

class PHY_MIB {
public:
	u_int32_t	CWMin;
	u_int32_t	CWMax;
	double		SlotTime;
	double		CCATime;
	double		RxTxTurnaroundTime;
	double		SIFSTime;
	u_int32_t	PreambleLength;
	u_int32_t	PLCPHeaderLength;
	double		PLCPDataRate;
};

but in ns-2.28, the code of PHY_MIB class is changed and no
RxTxTurnaroundTime is defined.

And I can not see any usage of RxTxTurnaroundTime both in ns-2.26 and
ns-2.28

THere's code with ns-2.26 where RxTxTurnaroundTime appears, but tx_sifs ,
tx_pifs_ and tx_difs_ seems do not appear somewhere else.

	tx_sifs_ = sifs_ - phymib_->RxTxTurnaroundTime;
	tx_pifs_ = tx_sifs_ + phymib_->SlotTime;
	tx_difs_ = tx_sifs_ + 2 * phymib_->SlotTime;

can anyone tell me how I make RxTxTurnaroundTime to work?

Hi,there
Maybe you can add "Queue/RED set q_weight xxx" at the beginning.Or try to 
avoid using "set sth [new Queue/RED]", in which case NS doesn't call the 
initialize_params() in RED to initialize the q_weight value,so it will be 
-1 by default.Thus a seg fault will happen.
Hope this helps.

Dear all,

I am building a simple wireless network model using 802.11. However, I seem 
to be observing the same throughputs whether the separation between a 
wireless node and base station is 2m or 100m. I have found how to set the 
transmission range, but there is still no reduction in throughput as the 
receiver moves away from the base station. I would be very grateful if 
somebody could tell me how to implement this.

Best wishes,

Adam

Hi,

I tried the following code in order to access the neighbords list of a node
using AODV.


/**********************************************************************************************/
Code I used :

Olivier,

really i don't see anywhere the link between the neighbour list in C++ and
the
variable neighbour_ you say. I'm making a job with AODV and QoS routing, and
i've made a Tcl command for AODV agent to show its neighbour list and their
delays between the agent.

I post it for you:

if(strcmp(argv[1], "show-table")) {
     AODV_Neighbor *nb = nbhead.lh_first;

     tcl.evalf("puts \"\nDelay Table of Node: %d \"", index);
     tcl.evalf("puts \"\tNode\tDelay\"");
     for(;nb;nb=nb->nb_link.le_next ){
     tcl.evalf("puts \"\t%d\t%f\"",nb->nb_addr, nb->nb_delay);
     }
        return TCL_OK;
   }
You must paste it or something similar in the command function in the AODV
agent. However, the nb_delay attribute you can see should be deleted or
implemented in the aodv_rtable.

I hope this could help you.

Bye Olivier.

/******************************************************************************************/


Then when I tried to recompile ns, I made "make depend" and then "make" in
the ns directory and I got the following error :

/******************************************************************************************/
error I got :

In file included from ../../../config.h:54,

                 from tr-stat.cc:24:

/******************************************************************************************/


Is it because of this : "However, the nb_delay attribute you can see should
be deleted or
implemented in the aodv_rtable" that I did not understand ?

I really wish someone could explain me why I got that error and what I
should do to correct it.

Thanks a lot,

Olivier.

Try this:

1.Open two files at the beginning of your script 
	set fo [open simple-out1.tr w]
	set f1 [open simple-out2.tr w]

2.in your record procedure, save data in the files like this 
	puts $f0 "$now [expr $bw0]"
	puts $f1 "$now [expr $bw1]"


3.then call xgraph with this command:
	"exec xgraph simple-out1.tr simple-out2.tr "

Don't  forget to close the files before calling xgraph 

Good luck

I guess that you are using the default two-ray ground reflection propagation 
model. In this case you get only 100 or 0% throughput. You should replace it 
by the shadowing propagation model which is much more realistic. Then you 
will get a gradual degradation with a growing distance.  

Best regards, 
Daniel.

I've never used 'make depend' in order to compile ns2. The error you paste 
don't have any relation with aodv or the nb_delay atribute.

I used the nb_delay attitrbute (double) in the neighbour class, in the 
aodv_rtable.h file. Because you don't use it, you must delete this line:

	tcl.evalf("puts \"\t%d\t%f\"",nb->nb_addr, nb->nb_delay);

or delete 'nb->nb_delay' and '%f' in it.

I think, that HZ jiffies in kernel doesn't affect on accuracy because
it's only a frequency when the schedule() function is called (main
schedule procedure in linux kernel). But the 2.6.x kernel has a great
improvements in speed if you compare it with 2.4.x family, especially
when you speak about the running in high-priority mode (using nice -19
command)

Now i'm working on another real-time emulation extension in ns-2. And
after i would like to measure performance with basic ns-2 extension
and extension of Daniel Mahrenholz's team with their improvements(see
it here: ivs.cs.uni-magdeburg.de). I will publish the result later.

But in any way we are making the same business =), so i hope my
results will be interesting for you also.

With best regards,
Sergey Semionov

I think that you should check the NS-2 manual
for "Worm Model" simulation in page 353 of the
manual.

I have never tried it but the manual there describes
such kind of simulations, using Worm model propagation
characteristics.

Subject: [ns] RAMP - errors!
Message-ID: <018301c604c6$6caa3e90$7221258a@vpn.elec.qmul.ac.uk>

Hi,

I've been trying to get RAMP (Rapid Model Parameterization) to work but it gives errors. I've done make to get http_connect & http_active & tried to run ramp with a command like this: (as given in the readme file)
 ./RAMP tracefile 1000 128.9.0.0/255.255.0.0 

where tracefile is my tcpdump trace.

The first error it gives is that usr/sbin/tcpdump: not found. Fair enough, such a file doesn't exist! I found a tcpd.exe somewhere else & tried with that. That got rid of the error, but it's not doing what it's supposed to do:(

The other erros are things like dat2cdf not found. I changed dat2cdf to ./dat2cdf on the RAMP file. That eliminated the error & it created a set of files. However, the files are empty!

Also, now it gives a set of errors saying uninitialised values in io.pl & io.www.pl. 

And it's the same with both ns-2.27 & 2.28.

What am I doing wrong? Any tips will be greatly appreciated!

Could I be using the wrong file format of tcpdump? If so, can somebody kindly give me a link to where I can get some sample files of the correct format?

Thanks in advance!

Message-ID: <9FFEE39DADA4A442B06FB5673765F410D062BB@CSD-EXBE-VS1.lsbu.ac.uk>

Hi, Guys
can any body highlight in wireless3-out.tr these lines 
 
We see routine beacon broadcast/solicitations sent out by HA/FA and
the MH. Initially the TCP pkts are handed down to MH directly by its
HA. As MH moves away from HA domain into the domain of the FA, we find
the pkts destined for MH, being encapsulated and forwarded to the FA
which then strips off or decapsulates the pkt and hands it over to the
MH. 
 
These paragraph is from 
http://www.isi.edu/nsnam/ns/tutorial/
 
actually....i want to know where is routine beacon
broadcast/solicitations
make the line bold and reply me...thanks

While running the script, you may see warnings like "warning: Route to
base_stn not known: dropping pkt". This means that as the MH moves
from the domain of one base-station into domain of another there may
be interim periods when it is not registered to any base-station and
thus doesnot know whom to forward pkts destined outside its domain. On
completion of the run, ns and nam trace output files
"wireless3-out.tr" and "wireless3-out.nam" are created. The nam output
shows the movement of the mobilehost and traffic flow in the wired
domain. The ns trace output shows traces for both the wired nodes as
well as the wireless domain. We see routine beacon
broadcast/solicitations sent out by HA/FA and the MH. Initially the
TCP pkts are handed down to MH directly by its HA. As MH moves away
from HA domain into the domain of the FA, we find the pkts destined
for MH, being encapsulated and forwarded to the FA which then strips
off or decapsulates the pkt and hands it over to the MH.

Thanks a lot for the quick reply!

No, I'm not using long traces - so that can't be the problem.

I'm running it on cygwin. Don't think that would be an issue either. (ns,
nam, xgraph etc. all works in it)

Any ideas?

Thanks!

hi friends,
    I searched for various video traces(from mentioned links in ns2 user-mail) and used them in "Video_trace.tcl" script (by Michael Savoric) but it gives me segmentation fault as well bad  file size fault.
  So with refrence to ns-user mail list I got solution that use separate programm for convertion of trace file and then use converted trace file in programm.
   It works but only shows NAM window and when I go for play, it doesnt run....
    Whats problem I couldnt understand.
  Also I used these converted Video traces in  tcl/ex/tg.tcl script , I got same 
  problem....What is this.?
   Whether trace file gets corruped ? plz give me solution....    Also if anybody having script that converts MPEG video traces into binary form, its great help for me ....
  So that I can use it directly into my ns2.
  Thanks in advance...........

Message-ID: <252d6e1c0512200122u7a8d99e9o2308ffcd212c16ca@mail.gmail.com>

Hi all,

I am implementing some security extensions to AODV protocol.  I am having
some doubts....
1)   How can I know the location information ((x,y,z) co-ordinate form)  of
a mobile wireless node at protocol design time as i required to use the
location information while sending a packet ?
2)   How the co-ordinate system in ns/nam ((x,y,z) co-ordinate system) is
mapped with actual location ? As the transmission range is described in
meters , how can we know depending on the location (x,y,z) information
whether two nodes are in transmission range or not ?

Thanks in advance...

Regards
Anupama

Try descompressing the targz in your GNU system, because it could be a problem 
with the privileges of the files, wich are not considered in your fucking 
Windows system :). Try this, if not work, send us another message.

Hi all,
   
  I have sent many mails regarding building AOMDV in ns-2.27 but no answer. So the other option is to build ns-allinone-2.1b4a the package for which AOMDV was developed for. However I'm not too sure which platform shall I use for a successful installation. Could anyone advise me on this matter.
   
  Thanks

Hi,

The best thing to do is:
1) switch to Linux
2) copy "ns-allinone-2.29.1.tar.gz" from Windows folders to e.g.
/home/yourhome/
3) decompress: I used "ark" under KDE (Slackware 10.2) but "tar -xvf
ns-allinone-2.29.1.tar.gz" should bo OK
4) the next you know

If there is TDMA amonf clusters then there should be "no contest" and hence

If nam doesn't run that means "perhaps" the format is not supported as nam
is not perfect! I have no check at this time though. check out "trace" file
for what you want to observe (I think it's graphs which should interest you
more than running pkts).

Hi Anupama,

Answer to your first question is as follows:

MobileNode * curNode = (MobileNode *) (Node::get_node_by_address(id_)); //
id_ is the id of node
double x,y,z;
curNode->getLoc(&x,&y,&z);

This will assign the X,Y,Z coordinate value to your local variable.

I hope this helps.

Hi all,

I plan to create wireless link 54Mbps for 802.11g. But the default in
NS-2
for wireless link is 1Mbps.

Does anyone know how to change it to 54Mbps?

Thanks in advance.

Hi,

I have a similar problem (I am able to get the MobileNodes), but I need to
get access to a list of the neighbors of this node. In my case, I want to
use OLSR, I need to know which nodes are available in the current network,
but it would be already enough if I would get information about the
neighbors of my current mobilenode.
I wanted to use neighbor_list_ (derived attribute from class node), but this
attribute is allways 0, thus I can't get any neighbor information for my
current node

I hope anybody can help me.

Best regards,
Fabian

Hi,

One of solving this problem can be as follows

int findNeighbors(int *neighborList)
//returns the total number of neighbors and populates neighborList
{
    MobileNode * curNode = (MobileNode *)(Node::get_node_by_address(id_));
    if(curNode==NULL)
    {
        printf("findNeighbors Error: Mobile node object points to NULL\n");
        exit(1);
    }
    double curX,curY,curZ;
    curNode->getLoc(&curX,&curY,&curZ);
    if(curX<0||curY<0)
    {
        printf("findNeighbors Error: Coordinate of mobile node out of
range\n");
        exit(1);
    }
    MobileNode * otherNode;
    double ox,oy,oz;    //Location of other mobile nodes

    int neighborCount=0;
    //neighborList = new int[numNode];
    for(int i=0;i<numNode;i++) //numNode is total number of mobileNodes
    {
        otherNode = (MobileNode *)(Node::get_node_by_address(i));
        if(otherNode==NULL)
        {
            printf("findNeighbors Error: Mobile node object points to
NULL\n");
            exit(1);
        }
        otherNode->getLoc(&ox,&oy,&oz);
        if(ox<0||oy<0)
        {
            printf("findNeighbors Error: Coordinate of mobile node out of
range\n");
            exit(1);
        }
        double dist=sqrt((curX-ox)*(curX-ox)+(curY-oy)*(curY-oy));
        if(dist<=250.0)
        //Node lies in the transmission line
        {
            neighborList[neighborCount]=i;
            neighborCount++;
        }
    }
    return neighborCount;
}

This code assumes that mobile nodes have default transmission range of 250
m. It will not be tough to tweak it for heterogeneous mobile nodes.

Cheers
Anup

Hi All,

I have found the solution to my problem.


MobileNode * curNode = (MobileNode *)(Node::get_node_by_address(id_));
        assert(curNode!=NULL);
        WirelessPhy * _phy =NULL;
        _phy    = (WirelessPhy *)(curNode->ifhead().lh_first);
        assert(_phy!=NULL);
        _phy->Pt_=NewValue;

If there is anything wrong with this approach, please let me know about it.

Thanks
Anup

Thank you very much for your help. 
Theoretically I didn't want to implement a logic for a spanning tree of
neighbors and hops to every destination in a partitioned network, because I
think that this should be task of the underlying protocol (OLSR) and provide
me with these information (for example the neighbor_list_ from class node),
but firstly it seems to me, that it is not possible to use this attribute in
a wireless scenario and second it seems to me, that it is not possible to
get access to the neighbor information with the current OLSR implementation.
I already saw too, that God::instance()->IsNeighbor works very similar to
your code, so I think I will use your code and implement the logic by
myself.

Changing the radius should not be the problem, because I will set a range
attribute for the application and bind it to TCL.

Thank you really very much for your help and inspiration.


Best regards,
Fabian

Dear all,

I am working with a simple wireless model and have a query about the 
distCST_ value that is displayed when the file is run. Using TwoRayGround 
propagation it is 550. This makes sense. But using shadowing propagation the 
number is huge (about 300 digits before the decimal point!). However, this 
doesn't seem to affect the results. Can I just ignore it?

Thank you in advace for any advice.

Message-ID: <b2fe492d0512210811q23fa477cn4025ee867e463d1a@mail.gmail.com>

Can anyone provide a link OR an example on how to use PriQueue (Priority
Queueing)? What should be done more in addition to specify DropTail/PriQueue
while setting up a link? As I suppose I need to set-up some parameters for
settiing priorities for different traffic types, Do I..?? How can I do it??

When having problems, one should always do

thanks for your answers, I just have seen that the error I was talking 
about is not important for the re-compilation of NS, and we don't have 
to take care about it.

Hi Shahram,

Thanks for the email. However i am more interested in understanding energy
issues at application layer.

Lets say there are two nodes n1 and n2 in a wireless mobile environment. An
FTP agent attache on n1 is sending a file of 1KB to n2. I want to know how
much energy was used by n1 in sending that file and how much was used by n2
to recieve that file. We have to keep in mind that there may be
retransmissions due to collision of packets. So i was wondering how can i
get this information at the application layer. Any inputs on this issue will
be highly appreciated.

Thanks
Anup

I don't know the key to success, but the key to failure is trying to please
everybody.
  - Bill Cosby
My mother drew a distinction between achievement and success. She said that
'achievement is the knowledge that you have studied and worked hard and done
the best that is in you. Success is being praised by others, and that's
nice, too, but not as important or satisfying. Always aim for achievement
and forget about success.'

Subject: [ns] Dropping packets in the queue
Message-ID: <395e46db0512211436w7bcb9460w8200968651076054@mail.gmail.com>

Hello,
I am changing link layer, implemented in ~ns/mac/ll.{h, cc},  to give
support for header compression. It occurs a strange thing as I change the
code to drop packets that doesn't have any context saved in the node.
Instead of dropping just the packet passed by parameter into the link layer,
all other packets that weren't specified are dropped in the queue(IFQ).

--------------           ---------
  Link Layer     =>       IFQ <--  here it happens the losses!
--------------           ---------

It follows a part of sendDown() method of LL class( in ll.cc):

*************************************************************************************
#ifdef HEADER_COMPRESSION_VOIP

    if (ch->ptype() == PT_CBR) {

            if( (ih->id() % 10) == 0 ) {    // if it is a uncompressed
packet
                            if ( ! (bkp_fields->existe_item(ih->flowid())) )
  // if there is no saved context with given "flowid"
                                    // save the identification of context
                                    bkp_fields->inserir(ih->flowid());

            }
             else {
                            if( bkp_fields->existe_item(ih->flowid()) )
                              printf("Compressed packet\n");  // goes to the
queue

                             else {
                               printf("Loss packet\n);
                               drop(p);  // it is dropped here, doesn't go
to the queue   <-- Here is the problem!!!
                             }
            }
 }
 #endif

      Scheduler& s = Scheduler::instance();
      // let mac decide when to take a new packet from the queue.
      s.schedule(downtarget_, p, delay_);
   }   // end of the method

*******************************************************************************************

Can anybody help me to solve this problem?

Any suggestion is welcome.

Thank you very much in advance,

Hi, All:
   I am implementing some routing protocol in network layer. I check the
source code and find out that when the packet arrives the desired
destination, it was received "immediately" by the application layer of
the destination.
 it did not invoke the recv method in the routing agent, which can be also
verified through the trace file (see the below section from AODV
simulation):

s 7.738382465 _7_ RTR  --- 6 cbr 532 [0 0 0 0] ------- [7:2 9:0 30 14] [0]

)

?????

My question is how can it happen? If it is specified by NS-2 by default.
Doe it mean that I cannot do anything in netlayer when the packet received
its destination???? Please advise!!!!!

Subject: [ns] simple qtn on bind function
Message-ID: <20051222071836.23498.qmail@web52207.mail.yahoo.com>


 Hi all,
         Here's a qtn on bind method in ns2. I have a
baseclass & 2 derived classes( different type of nodes
: edgenode & corenode ). Baseclass has a instance
variable (ptime) that both the subclasses use.

But there is a bind function in the subclass as well
as in the base class(?).

I can see in an example (tclexample1.tcl) the stmts as
shwn below :

 baseclass/edgenode ptime 1
 baseclass/corenode ptime 2 

 But cant find any :  baseclass ptime  ?????

Why would you guys think to have a bind function in
the base class too ? 
( I know that it works without having a bind function
in the base class !)

 Any thoughts???

There are many clusters in a wireless network. Sensors in every cluster collect information and delivery to their cluster head node. Then each cluster head aggregates info, and transmit data to a sink via other nodes(include cluster and non-cluster head nodes).In each cluster, TDMA is used. Mac based contention is used among clusters. How to simulate this network with two MAC coexistence? and how to set TDMA status when writing a routing agent? Thanks!!

Subject: [ns] Loading a large movement trace file
Message-ID: <32584626.1135259650709.JavaMail.root@pswm12.cp.tin.it>

Hi all,

I am experienceing the following problem:
I have a large 
movement trace file (around
200 nodes whose speed is updated every 0.5s
for 2000s of simulation), which is 40Mb in size
(evry line of the file 
is a setdest command).

When I run the simulation, it takes a very
long 
time (I do not know how much, I stopped
it after 30 mins)  after the 
"INITIALIZE THE
LISTHEAD xListHead" message is displayed
and before the 
actual start of simulation
(i.e. simulatied time 0 is not reached).

I 
think this is due to the large movement trace
file, but I am not sure, 
and I do not know what
to do to avoid that.

Does anyone have any idea 
about how to get
rid of such a problem, or any experience with
similar 
issues?

Thanks,

Marco Fiore

Message-ID: <B689ACAE7DCF7F4BA933EF549070994C01AC15C5@dlee07.ent.ti.com>

Hi,

 

I have been experimenting with the new 80211 model available from
http://spoutnik.inria.fr/ns-2-80211/. The model is quite accurate and
easy to use (especially because of the sample scripts provided in
ns-2-snapshot-20050907-14.1.tar.gz
<http://spoutnik.inria.fr/ns-2-80211/releases/ns-2-snapshot-20050907-14.
1.tar.gz> ).

 

However, as I understand (and because of my lack of overall ns
expertise), the ns-2 trace mechanism does not work with the new 80211
model.  Hence, I am unable to gather per-packet delay statistics from
the new ns 80211 simulation.

There are numerous examples (a tcl snippet is attached below) on the
ns-users mailing list archives that allow me to collect throughput
values from the various traffic sink agents that I connect in my
wireless simulations.  

 

Also, there are numerous examples in the ns-users archives that show how
to parse trace files generated by ns-2.  But, without ns-2 styled trace
support in the new 80211 model, I can't (am unable to) extract
end-to-end per-packet delay from the new 80211 model i.e. from injection
into the simulation by the traffic source till ejection of each packet
into the traffic sink.  Any suggestions and pointers will help me.

 

Thanks in advance,

Manish.

 

PS:

 

Heres a tcl script snippet that allows me to get throughput between the
CBR source and the sink/LossMonitor (also works for Null and TCPSink
agents).  I am interested in also being able to capture per-packet delay
from the CBR source, through the WLAN simulation, and into the
sink/LossMonitor.

...

set sink5 [new Agent/LossMonitor]

$nodes(0) attach-agent $sink5

set source5 [new Agent/UDP]

$nodes(1) attach-agent $source5

set cbr5 [new Application/Traffic/CBR]

$cbr5 attach-agent $source5

$cbr5 set packetSize_ 60

$cbr5 set interval_ 0.0066

$source5 set prio_ 5

$source5 set packetSize_ 60

ip-connect $source5 $sink5

$ns at 1.0 "$cbr5 start"

 

set f0 [open sink1.tr w]

proc record {} {

          global sink5 f0

 

          set ns [Simulator instance]

 

          set time 1

 

          set bw0  [$sink5 set bytes_]

 

          set now [$ns now]

 

          puts $f0 "$now [expr $bw0/$time*8]"

 

          $sink5 set bytes_ 0

 

          $ns at [expr $now+$time] "record"

 Hi everybody,
 
            I have simulated a wireless mobile adhoc network. In the trace files it was found that node_(2) is not sending any kind of packets to other nodes between 41 th second and 51 th second. But I found loss of energy from 98.8 to 98.2. I am confused why this loss of energy is happenning. Is there any hidden thing which we are not getting in the trace files or is it because of RTS, CTS packets.
            If it is because of RTS and CTS packets, please tell me how to see them in trace files. 
 
 Thanks in advance,

ns-allinone-2.1b3 is an old version and I think it is not compatible with
Fedora Core 3 because of the gcc version. 

Like my case, I use ns-allinone-2.1b6 and I CANNOT use RedHat 9.0 because
its gcc version is above 2.95. 

I suggest that you use RedHat version 7.0, 7.1, 7.2 or 7.3. Their gcc
version is less than 2.95.

As far as I know requires ns2.1b9a tcl8.3.2 and tk8.3.2 (and config file 
is trying to find these libs).
Install these two version (if you use the allinone packet these are 
inside of this packet) and try once again.
I hope this helps

Best regards,
Fabian

hi ,
 i don't know exactly, why it worked by making single change. But i made the change  by guessing it as hidden terminal problem.
 
 Exact reason is most welcome.
 
 The modified line is highlighted  with yellow and i have changed 20.0 to 10.0 in that line which is highlighted with blue.

Hi,

I also have that problem, infact in my case when running nam for a similar
scenario, it shows me node 0,1,2 and 3 a not defined until they actually
start the movement.

Another think which I need to ask you is that why have you attached the
same tcp to node 0 2 and 4 and sink to node 1 and 3. Can you use the same
agent on different nodes? Is that a requirement for the channel to work
properly or your just testing to see it works

Please let me know

regards

Qasim Iqbal

Could you please specify the OS you're using
and also the error message that is returned to
you?

You say that you have tried ./configure and make but
it fails to build. Please specify, in general, the (any) error messages that
you are receiving.

I had some problems with gt-itm and I might be able to help you.

Message-ID: <BAY102-F1582182F45F04A85D3269E2330@phx.gbl>

Hi all,

I'm using a simple topology of one line of nodes, but AODV seems to not 
recognize the linear path to the destination.

Does AODV automatically built up the routing table from the source to the 
destination or it is necessary to set up some parameters and call some 
functions?

Thanks a lot

Dario

You?re welcome, as ns-users we should help each other whenever we could.

About your first question, because I have tried to install it on RedHat 9, that?s why I know ?
And for your second question, before you install Linux, you can actually browse your Linux CD to read its README or RELEASE-NOTES, there usually will mention its gcc version.

Have a nice day!!

hai,
Thanks for your valuble suggestion.
But, i have two questions to you.
How do you know that ns-allinone-2.1b6 can not use RedHat 9.0?
How do you know about supporting gcc versions?

bye,
Y.Jaya Lakshmi.

ns-allinone-2.1b3 is an old version and I think it is not compatible with
Fedora Core 3 because of the gcc version. 

Like my case, I use ns-allinone-2.1b6 and I CANNOT use RedHat 9.0 because
its gcc version is above 2.95. 

I suggest that you use RedHat version 7.0, 7.1, 7.2 or 7.3. Their gcc
version is less than 2.95.

Message-ID: <20051224083439.26467.qmail@web34306.mail.mud.yahoo.com>

Hi,

I've tried everything to install ns-2 on an AMD-64
Opteron based server --(running Fedora Core 4) 
->including using the all-in-one and
build-from-individual-sources but all in vain.

OTCL configuration fails even when I specify TCL path
using the --with-tcl=/path to tcl/ option.

While, going through the ns mailing archives I found
some people have been engaged in making a patch to
resolve this issue, but the question nagging my mind
is - Is it only because it is unable to find required
libraries or something even more deeper? If not then
is the patch already ready?

Regards,

Sameer.

Message-ID: <8372803c0512240058j743ec88am76f13646f770cb1a@mail.gmail.com>

You have no specific problem with your Tcl.
Since you have installed it, you only have to
provide the path to it during configure with the
following parameter:

./configure --with-tcl={your tcl8.4.5 path} --with-tcl-ver=8.4.5--with-tk={your
tk8.4.5 path} --with-tk-ver=8.4.5

What is meant with "path" is i.e. /usr/bin/tcl8.4.5, or whereever is your
Tcl, Tk, etc

I also attach a page that might be useful to you when you will install the
other packages
for NS-2.
Try the instructions found here:
http://nslab.ee.ntu.edu.tw/courses/ns-tutorial/labs/lab1.html

I have used this method and I installed, with user priviledges, Tcl8.4.5,
Tk8.4.5, otcl, tclcl,
ns-2.29, nam-1.11, etc in my home directory under Debian Linux 3.1 where I'm
working.
I also got the same error as you when I did not specify the path to the Tcl,
Tk, etc.

Try the page above and I think that you will have no problems

Hi All,

I am new to ns2 (i.e: a student) and currently doing
some research work 
using NS2...my focus is on Dijkstra algorithm at the
moment...but the 
problem is that I don't know how to run
dijkstra.cc...As far as I 
understand, this is a standalone file which can be
directly called...but I 
doesn't seem to work...can some one please help me by
teaching how to run 
this file...

My another question is, does NS2 implement
Widest-Shortest Path or 
Shortest-Widest Path?...If either one is implmented,
how do I find how it is 
implemente?

Thank you,


mohammad hammad

Message-ID: <43AE9D2E.40509@wgserve.de>

Hi ns community...

We are happy to announce the first release of our new traffic generator
BonnTraffic.

It is a simulator and scenario independent, highly flexible, stand-alone
traffic generator for linux/unix-platforms. It is designed for
flexibility regarding the utilized simulators, the focused scenarios as
well as the traffic-type and its -characteristics. BonnTraffic therefore
offers a comfortable framework consisting of four major steps:
	1. scenario definition,
	2. traffic definition,
	3. traffic generation,
	4. traffic export.
BonnTraffic provides, analog to ns2, an embedded OTcl interpreter to
realize these tasks.

There are currently a well evaluated HTTP-model as well as a rudimentary
SIP-module (VoIP) integrated.

BonnTraffic is licensed under the GPL and obtainable from its web-page.
Just visit the BoMoNet page for further information:
	http://www.cs.uni-bonn.de/IV/BoMoNet/

Best wishes...

	---Bernd Roemer---

Dear all

I would be grateful if you could help me on how to get energy displayed as
shown in the article about energy model update in NS2.

e.g
[energy 979.917000 ei 20.074 es 0.000 et 0.003 er 0.006]

The meaning of each item is as follows:
 energy: total remaining energy
 ei: energy consumption in IDLE state
 es: energy consumption in SLEEP state
 et: energy consumed in transmitting packets
 er: energy consumed in receiving packets

at the moment i am getting something like this by running the MyTest.tcl
script
