Line 7: packet #610 received on node 2 from node 0
Line 8: packet #610 enqueued on node 2 (now with new destination / next

If you receive a packet, the receiver is still the destination.

Hope this clearifies you problem.,

Hi all..
I am trying to port olsr (version of inria) to ns 2.29.  It compiles but
gives the following linkage error between TCl and C++ objects on running any
simple script. Am using fedora 5 with gcc version 4.1.1.  I don't know much
about how TCL and C++ objects interact so any help or lead in resolving this
problem will be highly appreciated.

hi

 ?thanks for reply. my problem is there is no inforamtion when data is send from source node and there is no information when packet is dorpped (as there is no s and d in first colum) and i go to analysis this file all analysis files like throughput, jitter and all other work with s and r and d in starting. i can't analysis this tracefile.
i am not expert in linux and in  ns2. can u please suggest me how to analysis these type of trace files.
thanks in advance

Subject: [ns] Floating Point Exception (HSTCP / TCP SACK)
Message-ID: <4660319D.4040702@gmail.com>

Hi,

I'm trying to run an HSTCP agent in my simulation.  I was told using a 
TCP SACK agent and the following parameters would allow me to simulate 
an HSTCP agent:

#Create a HS TCP agent and attach it to node n0
Agent/TCP/Sack1 set max_ssthresh_ 100
Agent/TCP/Sack1 set windowoption_ 8
set tcp0 [new Agent/TCP/Sack1]
$ns attach-agent $n0 $tcp0

However, when I try to run this script I get an error "Floating point 
exception"

The line that's causing the problem is :
Agent/TCP/Sack1 set max_ssthresh_ 100

I have also tried :
Agent/TCP/Sack1 set max_ssthresh_ 100.0

Any ideas?

Hello users,
can anybody direct me to the program that coordinate the scheduling of activities in ns 2.  The reason is that i did an editing in dsred.cc in ~ns/ns/diffserv. i discover that all my additions were repeated thousand times. Say, if a variable T is added to something, it is added thousand times. i later discover i need to do my addition in the driver class. i opened different files could not see the file that captures all that we specify in the .tcl file.
Can anyboby help me. pls i am stucked here.
thank you in advance

if you have a code on diffserv scheduling using bandwidth, kindly forward it to me to serve as a guide to get the bandwidth of a link. thank ya

Subject: [ns] How to turn off the energy trace in old wireless trace format?
Message-ID: <56043.10.107.1.1.1180721878.squirrel@10.107.1.1>

Hello,
  Is there a way to avoid dumping the log of energy changes in the trace
file?
When I use the energy model available in the NS2, the trace file dumps out
lines like

N -t 10.008284 -n 4 -e 100.000000

  Every time there is a change in the node's energy this event in dumped
into the trace file. Because of this, the size of the trace file is
increasing a lot making it difficult to carry out post-processing of trace
files.
  Is there a way we can turn this energy trace OFF. I know we can choose
to turn off/ on agent trace, router trace,etc. (section 5.3 or 16.4 of NS
manual - http://www.isi.edu/nsnam/ns/doc/index.html). But I found no such
control
parameter for energy trace.


Thanks,
Kaustubh Jain.

Hello!
Trace graph 2.05 source code is available to download at 
http://www.tracegraph.com.
If you have an access to a Matlab Compiler (at least the one bundled 
with Matlab 6.1) for Linux/Windows or other OS
and could compile Trace graph 2.05 to make it available for free to all 
ns users, please email me.
Matlab libraries (mglinstaller or MCRInstaller files) for the target 
systems would also be required to run the compiled binaries.
Thank you very much in advance.

Best regards,
Jaroslaw Malek

             The Network Simulator ns-2: Frequently Asked Questions


Note:  This FAQ is now available at the project wiki:
http://nsnam.isi.edu/nsnam/index.php/Ns_Users_FAQ

    _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

        This is _very_ good advice, since asking the Right Question is

Message-ID: <5ec4446a0706011913q4056e294r8309336e53874a30@mail.gmail.com>

Hi all,
    When i run my tcl script about xcp, I got a float point exception.
I debug ns with gdb. When I wanted to display the value of cwnd_ in
window() of tcpreno.cc, gdb show me it is <incomplete-type> and
window() returned with 0. So It lead to a float point exception.
But what did <incomplete-type> mean? and how to fix it?

Best regards.

Hello!
I have a question that "tortures" me.
Does anyone know how the pointer target_ of a rtagent is being initialised?
I mean...:
every rtagent 'communicates' with LL and if i understood well, this is being
done through  the target_ pointer which is inherited from the Connector.
But i tried to find where this is done in tcl scripts and c++ code but i was
unlucky.
for example in the "add-interface" procedure we see that trough the line:
"$ll mac $mac"
the pointer "mac_" of /mac/ll.cc shows to the down-layer mac. (
mac_=(Mac*)TclObject::lookup(argv[2])     ).


shouldn't there be anything equivalent and for the pointer 'target_' so that
it shows to the ll ?

I would really appreciate any answer.
Thank you very much!

Did you write a traffic sim in the tcl?
Without the tcl file no one can do anything but guess.

Subject: [ns] to specific node
Message-ID: <637621.7778.qm@web38712.mail.mud.yahoo.com>


Hello all,

I am an ns2 user, 
I am in need of sending a packet to a specific node
(say I have three nodes n0,n1 and n2). N0 sends a
packet to N1. When N1 recieves the packet, it will
check the source and destination using ip->dest and
ip->scr and if both match i.e. if it is from node 0,
it will generate a packet and send to N2.

I tried to implement this using the target found in
ns. From the results I saw, there are some problems. 

Can any one help me? i.e. how can I send to a specific
node?


Thanks, for your help so far

Subject: [ns] MAC level Trace File generation
Message-ID: <10911000.post@talk.nabble.com>


Hello Everybody,

I tried to figure out, how to generate a trace file at the Mac layer.
I'd like to see MAC level information for received and transmitted packets!

I tried the following:

Entry at mac-802_11.h
Trace *trace_mac_;

Entry at mac-802_11.cc

Mac802_11::command(int argc, const char*const* argv)
{
	if (argc == 3) {
		if (strcmp (argv[1], "log-target-mac") == 0) {
	 		 trace_mac_ = (Trace *) TclObject::lookup (argv[2]);
	  		if (trace_mac_ == 0)
	    			return TCL_ERROR;
	  		return TCL_OK;
		}
}
}

And write to the trace file:

if (trace_mac_){
	sprintf (trace_mac_->pt_->buffer (), "%f %f",
Scheduler::instance().clock(), dataRate_);
	
	trace_mac_->pt_->dump ();
}

Entry at sim.tcl
At the TCL-file I generated the instance procedure 

set mactracefile [open mac.tr w]

Mac/802_11 instproc statstrace { tracefd } {
	set T [new Trace/Generic]
	$T target [[Simulator instance] set nullAgent_]
	$T attach $tracefd
	$T set src_ [$self set addr_]
	$self log-target-mac $T
}

#call the function statstrace and hand over the link to the trace file.
Mac/802_11 statstrace $mactracefile

To generate a new Trace object and allocate the Trace object to a trace file
$tracefd.
But when i run my simulation file, i got serveral error messages. 
Can somebody help me with that problem ?

Thanks a lot,

HB

Hallo Matthias! thank you for your resonse! I searched the archives of the
last two months but i didn't find anything relative. Is there any chance
that you remember the subject of the mail?
or perhaps you can tell me whatever you remember about the procedure of
sending real data.
I would be very grateful indeed!
Thank you very much. I'll keep on searching ...
Danke!

I tried sending this to the list yesterday, and I don't think it went 
through.  I apologize if you're seeing this again.

I've seen a few different ways to use High Speed TCP (HSTCP) in NS2, and 
just wanted to get a definitive answer, if there is one.

The resources I have generally talk about using SACK and changing a few 
parameters in the Agent.  I'm using version 2.28.

Hi,

   I already made the same question, i'm using the NIST WiMAX module,
and the trace files are hard to analyse. So what i did was to use this
method: http://140.116.72.80/~smallko/ns2/tool_en.htm  ,made by
Chih-Heng, Ke.

 With the c++ functions you get 2 files which the default name is "rd"
and "sd".  This files are easy to analyse, and i'm getting results
that "look good", but unfortunately i can't tell if it is reliable
method to use, i'm just using, the best thing was to know exactly how
to interpert the trace files, but for me, at this moment i don't have
time.
 I already asked in the forum but i got no opinions about the method.

kindly, Tiago Junqueira

My fellow NS-2ers and soon to be NS-3ers alike. I would like some quick
general advice.

I have been trying hard to implement 802.11e on NS-2.30.
There are versions from Ni Quang, TKN, INRIA, etcetera. I have downloaded
them all.
What version do you reccomend for NS-2.30?

I am afraid of making big changes and not being able to restore my code to
the way it was working. Any advice for restoring?
NS-2 can be really frustrating!

 I would love to use TKN but i cannot get it to work! I had problems
implementing it. The website says that it is for NS-2.26 and NS-2.28.
Does this mean that it will work on NS-2.30? Because surely it is more
up-to-date!

Irish Student

Im very interested in TStat for NS-2

I have the tar file tstat-1.01 but I do not have acess to the installation
manual.
I have NS-2.30, and its working nicely.
Could someoneme a quick idea of what I should do? I am having trouble
installing packages and "snapshots"  in general.

Should I replace my files in my NS-2.30 folder with the set of files in the
package completely?
For instance in the package there is a Makefile. NAturally I already have a
makefile. Should I just update my old one, or should I replace my
makefile with the new one from the package everytime that I want to use it?

I would appreciate to get your ideas. If anyone wants a copy of tstat, I
will gladly email it to them.

hi all,
My simulation is simple, 1 rnc, 1 bs, 4 UEs, Mpeg4 traffic flowing from IP
network to the UEs.
Why is it that when I am using UMHS RLC mode, packets flow through the rnc
on the UMHS (recv() in um-hc.cc) mode whereas they go up the UEs through the
UM (recv() in um.cc) mode ???

Message-ID: <4bb1b4060706050630t5a7f3f9exbc6f50df4c7dabe3@mail.gmail.com>

Hi,

 In the example datarate.tcl it's possible to change the modulation
used by the Mobile Node  the command [$SSWithWiMax set mac_(0)]
set-diuc $modulation.
 I changed the direction of the flow, and the node that was the
SinkNode is the source, and the Mobile Node is receiving the packets.
 My question is, How can i change the modulation used by the base
station, if it is not possible to use the command: [$BSWithWiMax set
mac_(0)] set-diuc $modulation?


   Thanks in advance, Tiago Junqueira

Hello,
I'm trying to find this algorithms :Weighted Round Robin, Oldest Queue, Longest Queue, Total Queue Length and Total File Lenngth to simulate it for my project. At least one of them. Could anyone tell me from where I can find them? 
Although I have to find the sending delay in a wireless transmission between 10 nodes, I found a file named cbrgen.tcl that I could modify, but the nodes (users) have diffrent type of rates (they are from diffrent type of QoS) and there I can  put only one rate in the variables; and what's the meaning of seeds.

I'm a beginner in NS, and because i don't know where to look, these things freak me and the License exam is at the door: knock, knock...

Thanks in advance.

Either you aren't recompiling the simulator, or "Protoname" isn't written 
always in the same way (the protocol name is case-sensitive).

fran

Hi,

 I think you're talking about the awk scripts to interpret the output
file given by the simulator, or not? Because that files look for the
"d".
 I was talking about the second method:

"[Method 2---modify C++ code]

        The basic idea is to insert two fields, sendtime_ and pkt_id_,
in the hdr_cmn header. When packets are sent, the packet id and send
time is recorded in the sender trace file. Then when packets are
received at the destination, the packet id and receiving time is
recorded in the receiver trace file. So I prepare two agents, mudp and
mudpsink to do the jobs. Mudp is the extension of udp agent. It only
overrides the sendmsg function to keep download the packet id and
sendtime in the user specified file."

The agent by itself records special events needed to calculate Jitter,
Data loss and delay. This is a way to measure the channel
characterists with UDP flows.

Hi,

Im about to upgrade to Windows Vista if all my software is compatible.

Has anybody used Cygwin and NS-2 on Vista? If you have, did you have any
problems with it?

I'm using cygwin 1.5.24 and ns-2  2.31 on Vista Home Premium. There
was no problem on installing it, but a few test have failed on
validation (as promessed in the tutorial).

I recomend you to use all-in-one package and install a full cygwin
(default installation does't install some packages needed).

Subject: [ns] NIST- About the "Couldn't schedule timer" error,
	comparation with the debug files
Message-ID: <4bb1b4060706060815n7425cf1co1881003133b37d8b@mail.gmail.com>

 Hi,

 I turned on the 2 debug commands," Mac/802_16 set debug_ 1" and i
added the following line to the file Makefile "-DDEBUG_WIMAX".
 First i executed the script with the parameters:

WimaxScheduler/BS set dlratio_ 0.56
Mac/802_16 set frame_duration_ 0.010
Mac/802_16 set fbandwidth_           7e+6
Phy/WirelessPhy/OFDM set g_  0.25

I got this error message:
"Couldn't schedule timer"

and then i executed with this parameters:

WimaxScheduler/BS set dlratio_ 0.56
Mac/802_16 set frame_duration_ 0.010
Mac/802_16 set fbandwidth_           6.999999999e+6
Phy/WirelessPhy/OFDM set g_  0.25

and i didn't got any error. The difference between the two debug files
is shown bellow.
 First I would like to ask, the difference between 7e6 and
6.999999999e+6 is 0.001 hz of channel size, so i can use the value
6.9..9 instead of 7e6, and the results will be almost the same?

 The big difference between the two debug files is:

 From the file without errors, with 6.999999999e+6 hz of channel size:

At 0.045431 in Mac 1 packet received (type=MAC) mngt=2

 From the file with error, with 7e6 hz of channel size:
In Mac 0 max data=223 (burst duration=6, b_data=59)

 The other differences are shown bellow (made with the utility "diff"
to compare files ). The PSleft is different, since the bandwidth was
different.

Subject: [ns] NIST- it's correct the example wimax1_teste.tcl
Message-ID: <4bb1b4060706060825k16c5104cje5c37d0ba47824b0@mail.gmail.com>

Hi,

  I was testing the example wimax1_teste.tcl, after running, i executed:
grep ^r out.res | grep MAC | grep -c cbr
grep ^s out.res | grep MAC | grep -c cbr

 and the results were Packets sent=100, Packets received =100.

 And then i changed the
set gap_size 0.0005 ;#compute gap size between packets

 and i was expecting to have 1/(0.0005) [pkt/sec] *100 [sec] =200000 pkt sent,
but after running the command:
grep ^s out.res | grep MAC | grep -c cbr

 I got 119423, so the command grep ^s out.res | grep MAC | grep -c
cbr, is not valid if the bandwidth requested by the source is bigger
than the bandwidth available in the channel?

What exactly is this structure used for?

Is it an all-purpose packet header which can act for TCP, UDP, ARP, etc, 
etc?

Hello,

I'm trying to find this algorithms :Weighted Round Robin, Oldest Queue, Longest Queue, Total Queue Length and Total File Lenngth to simulate it for my project. At least one of them. Could anyone tell me from where I can find them? 

Although I have to find the sending delay in a wireless transmission between 10 nodes, I found a file named cbrgen.tcl that I could modify, but the nodes (users) have diffrent type of rates (they are from diffrent type of QoS) and there I can  put only one rate in the variables; and what's the meaning of seeds.

 

I'm a beginner in NS, and because i don't know where to look, these things freak me and the License exam is at the door: knock, knock...

 

Thanks in advance.

Hello,

I'm trying to find this algorithms :Weighted Round Robin, Oldest Queue, Longest Queue, Total Queue Length and Total File Lenngth to simulate it for my project. At least one of them. Could anyone tell me from where I can find them? 

Although I have to find the sending delay in a wireless transmission between 10 nodes, I found a file named cbrgen.tcl that I could modify, but the nodes (users) have diffrent type of rates (they are from diffrent type of QoS) and there I can  put only one rate in the variables; and what's the meaning of seeds.

 

I'm a beginner in NS, and because i don't know where to look, these things freak me and the License exam is at the door: knock, knock...

 

Thanks in advance.

 When I was trying to installed the other wfq-1.2.5 i get an error that want to install "sudo apt-get host " or something like this.
Now when I'm trying to ns example.tcl... I get another error: 

"example.tcl does not exist (Authoritative answer)"

 I'm thinking to extract the package wfq-1.2.1 from ns 2.31, because I found another wfq-1.2.5 and i think this one will work. Could anyone tell me how to extract that package: I want to try with the new one: maybe that have some bugs fixed for the renew version.
     I did passed through that earlier error by 
./configure              in the ns directory
make
make install


but now i get another error: something like:  "Floating point exception (core dumped)"
I hope that to be an passing error. I will try to restart my computer and pray to work.

Subject: [ns] Catch packets in any node
Message-ID: <46672697.6060702@gmail.com>

Hi,

I'm trying to find a way do catch and modify packets that pass through a 
node.

I have a structure like this:

(tcp)N0--------N1--------N2(sink)

There are no agents associated to N1.

I need to catch a packet in node N1, modify it and send it to right 
destenation (in this case N2).

Does anyone know how to do it??

 I'm quite desperate, so I would be very greatful if anyone could help 
me please.

Best regards,

Alexandre Malh?o

Message-ID: <8c17cb3b0706062012n38b1846cuc54292ec2b0a2d99@mail.gmail.com>

Hello NS-Users,

 I have started working with the reference paper mentioned below for
performance comparison of two routing protocols based on random
mobility model.  The PDF values for the
cbr-50-30-4-512,scen-500x500-0-20 is very high( I get around 98%). But
the given values in the graph is only 65%. The same thing happens for
cbr-50-40-4-512 also. I am not knowing where the error is . Any
suggestions in this regard will be of great help for me.I am also
attaching the files for your reference.
I am using ns-2.28 version.

Message-ID: <434dc22c0706062039m44f62babs97549a65c7f925fb@mail.gmail.com>

Hello all,
   I have 2 questions:
1. Is it possible to show traffic patterns with different colors between
wireless nodes (just like how its possible for wired scenarios) in ns-2? If
so where could i find a demo?
2. If i need to load the NAM (animation) on to a powerpoint in the form of a
movie, is it possible? If so how do i do it?
I appreciate your time and help. Thank you.

Message-ID: <20070607043107.45208.qmail@web30508.mail.mud.yahoo.com>

hi all
 
i have been trying to install ns-2.26 on fc5. Already applied a patch and replaced god.h. The latest problem is of webcache/webtraf.cc. It gives error and stops make.
 
Following is displayed
 
webcache/webtraf.cc: In member function ?virtual int WebTrafPool::command(int, const char* const*)?:
webcache/webtraf.cc:417: error: ?lt? was not declared in this scope

make: *** [webcache/webtraf.o] Error 1
Ns make failed!
See http://www.isi.edu/nsnam/ns/ns-problems.html for problems
 
 
Kindly reply how to solve this. I want ns 2.26 on fc5. other option is downgrade compiler. There also i m struck with how to let ns-2.26 know it has to use older version.
 
 
Anjali

when i am trying to add new a node to the topology its giving segmentation

How i can overcome by this this problem ( or i have to change into #Set NS

Hi, everybody:
   
  I program using STL. there is a member function of templete class map, I use the fucntion well with visual studio 2003 .net, but when I compile those code under cygwin, the compiler says this fucntion is wrong, why?
  I code my program with standard C++.
   
  In the book <<C++ prime plus>>, the writer says he have test his code, in the book, under vstudio 2003 and linux with gcc version 3.3.1.
   
  my gcc version for cygwin is 3.3.1. Then I install a new version 4.0.1, it gives the same error information.

Hi all,
In Eurane, I managed to get packets arrive here:

void UM::makeSDU(Packet * p)
{
   hdr_cmn    *ch;
   hdr_rlc    *llh;

   assert(p);
   ch = HDR_CMN(p);
   llh = hdr_rlc::access(p);

   ch->ptype() = llh->lptype();
   ch->error() = llh->lerror();
   ch->timestamp() = llh->lts();
   ch->size() = llh->lsize();

   uptarget_ ? sendUp(p) : Packet::free(p);
}

I am actually looking for this:    uptarget_ ? sendUp(p) : Packet::free(p);
Where do packets go after that ? I know it's up the stack but where exactly
in the code, what is uptarget_ and where is the sendUP() function located (
knowing that I am using UDP ) ??
please help me, I am stuck !!!

if you :

 # Set NS Addressing
  AddrParams set domain_num_ 9
  AddrParams set cluster_num_ {9 9 9 9 9 9 9 9 9}
  AddrParams set nodes_num_ {9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 etc..}

p. example you will have no problema running your simulation.
Just raise the numbers.

Hi all,

I have tried to implement a new MANET protocol. I have made all the
necessary changes and recompiled using
- make clean
- make depend
- make
After all these, i can't run ns because there is no ns file under the
installation directory. Actually i get the error:
./ns: No such file or directory

Do i need to re-install ns?
Any ideas?

Your message to ns-users (attached below) was rejected
because it does not contain a subject header at all,
or because it does not contain a useful subject header.

Subjects allow people to quickly determine if messages
are relevant to them.  Please pick a useful subject
line for your message and re-send it to ns-users.

Useful subjects mention something about what part of ns you're
working with.  For example:
- "A few issues (fulltcp, parameters...) related to webtraf.*"
- "How does Agent::delay_bind_init_all() work?"

NON-useful subjects are things like:
- omitting the subject completely
- "help"
- "urgent"
- (most any one-word subjects)

Thanks for helping to make ns-users effective,

I tried to install it again... This time I gave it the parameter manual. And now I think that install was correct.
I didn't get no error in installing, but an error till persist  when i want to run the example :  example.tcl
This is: "Floating point exception (core dumped)"

IF I don't get this error fix, I need to try something else to simulate congestion in GPRS... any idea?!

 When I was trying to installed the other wfq-1.2.5 i get an error that want to install "sudo apt-get host " or something like this.
Now when I'm trying to ns example.tcl... I get another error: 

"example.tcl does not exist (Authoritative answer)"

 I'm thinking to extract the package wfq-1.2.1 from ns 2.31, because I found another wfq-1.2.5 and i think this one will work. Could anyone tell me how to extract that package: I want to try with the new one: maybe that have some bugs fixed for the renew version.
     I did passed through that earlier error by 
./configure              in the ns directory
make
make install


but now i get another error: something like:  "Floating point exception (core dumped)"
I hope that to be an passing error. I will try to restart my computer and pray to work.

Hello again,
I did founfd out some pach that install another patch: wfq-1.2.1 ( http://www.cc.jyu.fi/~sayenko/srpms/wfq-1.2.1.tar.gz ) , but now I can't run the example. I get an error like this:

Hello,

I'm trying to find this algorithms :Weighted Round Robin, Oldest Queue, Longest Queue, Total Queue Length and Total File Lenngth to simulate it for my project. At least one of them. Could anyone tell me from where I can find them? 

Although I have to find the sending delay in a wireless transmission between 10 nodes, I found a file named cbrgen.tcl that I could modify, but the nodes (users) have diffrent type of rates (they are from diffrent type of QoS) and there I can  put only one rate in the variables; and what's the meaning of seeds.

 

I'm a beginner in NS, and because i don't know where to look, these things freak me and the License exam is at the door: knock, knock...

 

Thanks in advance.

Is it necessary to change the BEB limit?
How the scheduler can be prevented from going back?

Subject: [ns] pcap file usage in simulation
Message-ID: <ca5165530706071650w352b496bt8af6bc09214f53e9@mail.gmail.com>

I am needing to run a simulation in NS2 that uses
pcap or tcpdump trace files as the traffic in the test.

I don't get any errors with this but I also don't get any traffic.
Do I need to explicitly set routing or is there something else I am missing?

My no-error-non-working example
#Create a simulator object
set ns [new Simulator]
$ns use-scheduler Heap

#Open the NAM trace file
set nf [open pcap_ex.nam w]
$ns namtrace-all $nf

$ns color 400 Green
$ns color 500 Yellow
$ns color 900 Red

#Define a 'finish' procedure
proc finish {} {
        global ns nf
        $ns flush-trace
        #Close the NAM trace file
        close $nf
        exit 0
}


###### Setup the Network ############################
set r(0) [ $ns node ]
set r(1) [ $ns node ]

####### Create the network links between nodes ######
set BANDWIDTH 80Mb
set DELAY 10us
$ns simplex-link $r(0) $r(1) $BANDWIDTH $DELAY DropTail

$ns simplex-link-op $r(0) $r(1) orient right

######## Setup the traffic types ########
set pcap0 [new Network/Pcap/File ]
##### open the trace file
$pcap0 open readonly network.dump

set null [new Agent/Null]
set tap0 [new Agent/Tap]
$ns attach-agent $r(1) $null
$tap0 network $pcap0
$ns attach-agent $r(0) $tap0

####### Notify that we are starting the run...
puts "Starting run..."

####### Run the above configured simulation
$ns run

Subject: [ns] New MAC protocol
Message-ID: <20070608150336.7z0k6xvpwokok8cs@imail.aub.edu.lb>

I have written a MAC protocol, and update some files like the packet.h
and the ones that we usually update if we were writing a new agent.
However when i wrote the corresponding TCL after I recompliled ns2 i
get an error saying Mac/mymac undefined command!! Is there any special
file i should update to make the tcl know that Mac/mymac is a new
prtocol. I mean I wrote the static class in the c++ but how will the
tcl find my protocol just by reading the command MAc/mymac. Isn't
there a special file that ns2 searches in to know where the class
Mac/mymac is in or something?

Thank you very much..I urgently need an answer ASAP

In your mymac.cc file, you need to define a Tcl class, say MacMyMacClass,
which is derived from TclClass. This class is in fact very simple, just to
let Tcl know that you have an object named Mac/mymac. After this, compiling
ns2 will do the rest of work and your Tcl code should understand your new
MAC protocol. The code is follows:

static class MacMyMacClass : public TclClass {
public:
     MacMyMacClass() : TclClass("Mac/myMac") {}
     TclObject* create(int, const char*const*) {
         return (new MacMyMac(&PMIB));
     }
} class_mac_mymac;

Hope this helps.

Hai.

Subject: [ns] TCP congestion window - Problem
Message-ID: <46696ffde748a@wp.pl>

Hi,
This may be simple, but I am wondering if TCP Reno is working fine in 
NS-2. I traced cwnd_ size, and it showed ssth like this:

0	cwnd_	1.000
0.04	cwnd_	2.000
0.09	cwnd_	3.000
0.1	cwnd_	4.000
0.15	cwnd_	5.000
0.15	cwnd_	6.000
0.16	cwnd_	7.000
0.16	cwnd_	8.000
0.2	cwnd_	9.000
0.2	cwnd_	10.000
0.21	cwnd_	11.000
0.21	cwnd_	12.000
0.22	cwnd_	13.000
0.23	cwnd_	14.000
0.23	cwnd_	15.000
0.24	cwnd_	16.000
0.27	cwnd_	17.000
0.29	cwnd_	8.000
0.37	cwnd_	8.125
1.37	cwnd_	1.000
1.42	cwnd_	2.000
1.47	cwnd_	3.000
1.52	cwnd_	4.000
1.53	cwnd_	4.250
1.57	cwnd_	4.485
1.58	cwnd_	4.708
1.6	cwnd_	4.921


At the begining TCP reno is performing slow Start till 0.27 when loss is 
detected. What happened next is strange for me... Shouldn't it reduce 
it's sending rate to 1 and start slow start again? It seems as it would 
be trying to perform Fast Retransmit/Fast Recovery instead, but finally 
it reduces cwnd_ to 1...
Could anyone explain it to me??

Best regards,
Kacper

Hello again,
i would like to ask you, how can we send packets just from one node-source
to miltiple nodes-neighbors.
Can it be done trough UDP agents? or shall i determine my own routing
protocol?
thank you.

Message-ID: <db92277f0706081807u37282d36pd4f2c597196332d8@mail.gmail.com>

Hi,

I would like to know how to set the bandwidth in a wireless mobile
simulation.
I found many examples and now I don't know what I must use:

MAC set bandwidth_ 2Mb;
LL set bandwidth_ 2Mb;
Rb = 2*1e6;  // 2 Mb and after... [   bind("Rb_", &Rb);   ]

Could somebody tell me what is the correct manner?
I am doing simulations in mobile ad-hoc networks and I need to set the
bandwidth of the communication to 2Mb. And I need to set the range to 250m
too.

Thanks in advance,
Ricardo.

Subject: [ns] Queue length from MAC
Message-ID: <aa7ce5df0706091103t4af1772fu15675d69cb2bcb2a@mail.gmail.com>

Hi all:

I am trying to obtain queue length (IFQ) information at the MAC layer.
I have checked the previous postings but couldn't find a coherent
answer. Has anyone been successful doing this?

So far, I have done the following changes without any segmentation
faults! However, I am getting a large number (134234....) when I
access the queue length.

Within the mac-802_11.c, I have added a hook to obtain the pointer to ifq,

if ((argc==3) & strcasecmp(argv[1], "down-target") == 0) {
                               if( (obj = TclObject::lookup(argv[2])) == 0) {
                                               fprintf(stderr, "MAC:
%s lookup of %s failed\n", argv[1],
                                                       argv[2]);
                                               return TCL_ERROR;
                               }
                               ifq = (CMUPriQueue *) obj;
               }

I am then using this pointer in the recvDATA function to access the
queue length--
((CMUPriQueue *)(ifq->prq_length())).

Please let me know if anyone has this working. I greatly appreciate
any help with this issue.

Thanks much!

Subject: [ns] Accessing queue length from MAC
Message-ID: <aa7ce5df0706091210h1b977e19g8f5bd2dfb1797ce6@mail.gmail.com>

Hi all:

I am trying to obtain queue length (IFQ) information at the MAC layer.
I have checked the previous postings but couldn't find a coherent
answer. Has anyone been successful doing this?

So far, I have done the following changes without any segmentation
faults! However, I am getting a large number (134234....) when I
access the queue length.

Within the mac-802_11.c, I have added a hook to obtain the pointer to ifq,

if ((argc==3) & strcasecmp(argv[1], "down-target") == 0) {
                             if( (obj = TclObject::lookup(argv[2])) == 0) {
                                             fprintf(stderr, "MAC:
%s lookup of %s failed\n", argv[1],
                                                     argv[2]);
                                             return TCL_ERROR;
                             }
                             ifq = (CMUPriQueue *) obj;
             }

I am then using this pointer in the recvDATA function to access the
queue length--
((CMUPriQueue *)(ifq->prq_length())).

Please let me know if anyone has this working. I greatly appreciate
any help with this issue.

Thanks much!
Stephen.

hi,

I wish to know the list of files i need to change after writing my new  
mac protocol, .h and .cc files. Cause I am having the problem of  
Mac/MYMAC not valid command i am getting although i am sure of the  
static class that maps c++ to tcl and the spelling of Mac/MYMAC and  
all these stuff.

Thanks guys

Hello,

I am looking for an implementation of the MAODV protocol to run some
benchmarks. I found a technical report online detailing the implementation
of this protocol for the 2.26 version. Can anyone tell me if there is a up
to date version, and where to get it if there is?

Thank you very much.

Subject: [ns] Help: error when using node generated by create_topology
	in NS format
Message-ID: <8372803c0706100005qce89c87ra2dcdb3f07dd7dda@mail.gmail.com>

Good morning

As it looks like from your code,
you are declaring the array n($i) only inside
your proc. However, because it is a local variable
it gets erased after the proc's execution. Therefore,
in your main script, when you try to access it with
$ns monitor-queue $n(3) $n(6) "" the interpreter
complains with an error.

What I would do in order to quickly solve this situation, would
be to declare the "n array" outside the proc and then "import" it
inside the procedure with global. This way, all changes made to
the array inside the proc, will stay and after the end of the procedure,
without disrupting
the execution flow.

That is why the interpreter cannot find the array in your main script.
According
to the script: it was never created (!?).

Hope that I have helped.

Regards,

-Fk

Hi Ntina,

Yes you can do that, using either the UDP or the TCP
protocol. However, bare in mind that in order to be sure
that this scheme will work, you need to define a separate
"sender-receiver" pair for every "node-pair" that of data exchange.

For example, if you want node1 to send data to node2 and node3, then
you should define 2 udp (tcp) senders at node1, one for each node receiver
defined at nodes node2 and node3 respectively. According to the
documentation
up to ns-2.29, defining one sender-node and connecting it simultaneously
with 2 receivers it might not work properly, meaning that it may only send
data to one of the two receivers, or to both, or to both of them in changing
orders (the latter case is an erroneous one, because not ALL packets that
should be sent get
sent, but only a subset of them). In any case, it is an unpredictable
behavior and
it should not be tried.

Defining separate sender-receiver pairs if the best way to go in my opinion.

Filippe and Anvay thank you very much for your reply!
I think that it can be done using UDP agents on each node and changing a
little the C++ code.
My thought is to make changes so that the sender can send to all nodes
through  defining iphdr->daddr() == IP_BROADCAST in the creation of the
packet. So i don't have to use more than one agent in each node or make a
loop in tcl.
I didn't try it yet, but i think it might work.
Please tell me your opinions.

Message-ID: <316889.51444.qm@web36902.mail.mud.yahoo.com>

Hello, 

I am trying to have a ns2.31+nam simulation which is like following: I have two coordinators starting two star PANs and I want that each coordinator to have five children from which it gathers data.
 My problem is that I am not sure on which criterion the end device is associating with a coordinator, I suppose the criterion is the distance. So, all is fine; but, what if I want that an end-device closer to coordinator A to be associated to coordinator B? Is it possible to simulate in ns2 that an end-device "knows" the 64-bit address of the coordinator it wants to associate to and the end-device will associate to that coordinator and no other? Or, is it possible that the coordinator to hold a table with the preferred 64-bit addresses of end-devices so that only those end-devices could associate to that coordianator?

Thank you for your time and help,

Dragos Bordeianu

P.S. How can I verify if I have got any answers to my questions? Thanks!

Hello all,

My ns is in the directory /home/wyt/ns-allinone-2.29, the patch is in the directory /home/wyt. I want to ask: what command should I use in order to install the patch successfully?
 
I used the following commands but they did not work:
 
cd /home/wyt/ns-allinone-2.29
patch -p0 /home/wyt/ns2292-gcc410.patch
 
It seemed that the terminal stopped and I did not know what happened.
 
Can anybody tell me how to use the PATCH command.? I read the mannual and still could not understand it, especially what p0 and p1 means.

Hi, the solution is always the same: Check your changes in the tcl

This relates to C++ stuff only. Tcl code is not compiled by "make".  
Thus, a successful "make" is not an indication that the Tcl stuff is  
correct, too.

Check all your tcl settings.

I guess that step 6 of the readme has not been applied properly:

6.  add to tcl/lan/ns-mac.tcl:

Patch is an Unix/Linux/Cygwin tools, not a ns-2 tool. See this short manual:

http://www.cpqlinux.com/patch.html

It'll be useful for make your own patches in future.

There are plenty of scripts written in many languages for that purpose,
just search in the mailling list or g**gle it.

Sincerely thanks for the responce Sven.


I still have the same error.
I set up the tcl/lan/ns-mac.tcl as follows:

 if [TclObject is-class Mac/802_11e] {
 Mac/802_11e set delay_ 64us
 Mac/802_11e set ifs_ 16us
 Mac/802_11e set slotTime_ 16us
 Mac/802_11e set cwmin_ 16
 Mac/802_11e set cwmax_ 1024

 Mac/802_11e set bssId_ -1

 Mac/802_11e set rtxAckLimit_ 1
 Mac/802_11e set rtxRtsLimit_ 3
Mac/802_11e set basicRate_ 1Mb  ;# set this to 0 if want to use bandwidth_
for
Mac/802_11e set dataRate_ 1Mb   ;# both control and data pkts
Mac/802_11e set cfb_ 0 ;# disables CFB
}



Should I follow these steps, step 7 seems to be very problematic

7. mac/wireless-phy.h:
   change
  enum ChannelStatus {IDLE, RECV, SEND};
 to
  enum ChannelStatus {IDLE, RECVING, SENDING};
   mac/wireless-phy.cc:
 replace all occurences of RECV and SEND (by RECVING and SENDING).

8. common/packet.h:
 add
  #define HDR_MAC802_11E(p) ((hdr_mac802_11e *)hdr_mac::access(p))

9. run ./configure; make clean; make depend; make in your ns directory

10. happy simulating :o) (e.g with the example script
../ns-x/mac/802.11e/multi_udpflows.tcl)


Sincere thanks and regards.

Subject: [ns] classifier:: recv
Message-ID: <fec531490706111434gf348f6bo34829b080324442d@mail.gmail.com>

Hello again!
I am really confused with the function Classifier::recv.
Can anyone explain me what exactly this dunction does? I would be really
very careful.
If i understood well, when a packet arrives from the LL layer then it is
being forwarded to the Address Classifier.
There, what are the possible "roads" that the packet can follow?
I am using DSDV routing protocol.


If the node is the receiver of the packet, then it will be forwarded to the
port classifier, right?

If the node isn't the receiver then it will be forwarded through the
default_target_ (pointer) to the DSDV agent, right?

When will a packet be forwarded to the DSDV agent through the port 255 from
the port classifier? (i don't understand exactly the usage of this port 255)
Please, please reply!!!

Subject: [ns] Nist- Diuc controls the Uplink channel?
Message-ID: <4bb1b4060706111833pc250190je130ec102839afff@mail.gmail.com>

Hi,


 Using the example datarate.tcl, the source is the Subscriber Station or MN0.
The frame is divided into 2, one for uplink another for downlink. The burst
profile for the Downlink is the Downlink Interval Usage Code (DIUC).
 My question is, why the maximum data transfered changes after changing the
modulation in the Downlink Channel, if the channel used is the Uplink controlled
with the UIUC?
 And if the MN0 is the sink node, and the fixed node is the UDP
source, it seems that the traffic also changes after changing the
DIUC? Is possible to have differente modulations, for the Uplink
channel and Downlink channel?

 Is there a command like [$wl_node set mac_(0)] set-diuc <modulation>,
to change the UL modulation?

 kindly, Tiago Junqueira

hi there,
i'm using this patch, and when i installed it i just followed the 10 indicated steps and it worked properly. The first time i tried to do this i got some problems and it didn't work, but it was something that i missed... as for me, i'm not using ns-2.30, it's ns-allinone-2.28 that i'm using.
  my problems were after i implemented an admission control algorithm, i couldn't include any header file to the application(including the header files i've never changed), donnow why, i tried to avoid the problem...until now i'm in a deep shit...
  hope it will work for u 2 ...
  good luck

Message-ID: <20070612110839.13300.qmail@webmail90.rediffmail.com>

  


Hi all,
I have a very simple but important query. When in AODV I try to execute the following statements:

void
AODV::sendRequest(nsaddr_t dst) {
// Allocate a RREQ packet
Packet *p = Packet::alloc();
struct hdr_cmn *ch = HDR_CMN(p);
struct hdr_ip *ih = HDR_IP(p);
struct hdr_aodv_request *rq = HDR_AODV_REQUEST(p);
aodv_rt_entry *rt = rtable.rt_lookup(dst);

  assert(rt);

printf("\n AODV RREQ sent by node [%d] to node [%d] at time [%f] \n",index,ih->daddr(),rq->rq_timestamp);
..............
...........
The value for time stamp fied is shown as zero, although according to me it should give the time when the packet was being sent. Can anyone tell me the reason behind this.

Thanks in advance.

Subject: [ns] Trace variables in nodes multi-homed
Message-ID: <200706121428.l5CESBMO024424@smtp2.dei.uc.pt>

 

Hi all,

I am using a simple procedure to record Window Size (cwnd_) variable of a
SCTP Agent. But if the nodes are multi-homed (for example, with 2
alternative paths to reach the destination), how can I distinguish the cwnd_
of the different paths?

I appreciate some help, please.

 

proc record_WindowSize {source file timetrace} {
      global ns 
      #Set the time after which thw procedure should be called again
      set time $timetrace     ;#seconds
      #get the current time
      set now [$ns now]
      set cwnd [$source set cwnd_]
      puts $file "$now $cwnd"
      #re-shedule the precedure (procedure calls itself)
      $ns at [expr $now+$time] "record_WindowSize $source $file $timetrace"
}

Hi again and thanks, I now have a clearer picture of the problem.

 PLease can I have your advice, I really need to get this working
I've followed the steps very closely, and have narrowed down the location of
problem to instruction 7.
"
 mac/wireless-phy.h:
   change
  enum ChannelStatus {IDLE, RECV, SEND};
 to
  enum ChannelStatus {IDLE, RECVING, SENDING};
   mac/wireless-phy.cc:
 replace all occurences of RECV and SEND (by RECVING and SENDING).
"

After successfully doing ./configure
successfully doing Make Clean
successfully doing Make Depend
I Run 'Make' and I get the error
mac/wireless-phy.cc: In wireless function  'virtual void
WirelessPhy::sendDown(Packet*)':
 mac/wireless-phy.cc:302: error: 'class Channel' has no member named
'RECVING'
make: ***

If I replace the RECVING with RECV I get the similar error:
 mac/wireless-phy.cc: In wireless function  'virtual void
WirelessPhy::sendDown(Packet*)':
 mac/wireless-phy.cc:302: error: 'class Channel' has no member named 'RECV'
make: ***

There are no solutions to this on the web

Here is the sendDown method


WirelessPhy::sendDown(Packet *p)
{
 /*

 if (em()) {

   if (Is_node_on() != true ) {

     */

     double begin_adjust_time = MIN(channel_idle_time_, temp);
     double finish_adjust_time = MIN(channel_idle_time_, NOW+txtime);
     double gap_adjust_time = finish_adjust_time - begin_adjust_time;

     last_send_time_ = NOW+txtime;
     channel_idle_time_ = end_time;
     update_energy_time_ = end_time;

     if (em()->energy() <= 0) {
      em()->setenergy(0);
      ((MobileNode*)node())->log_energy(0);
     }

  } else {

   // log node energy

Hi,
Let I had run a simulation during T seconds.
Let this simulation has To seconds of transient state. To < T.
Is there any instruction or method to keep the state of my simulation at
To and start another simulation with this state in order to avoid the transient
state each run.
Any suggestions are welcome,

Hello,
      Has anyone implemented HEED protocol for Ad Hoc Networks on NS 2 as it has been implemented in TinyOS earlier. Please let me know if anyone tried it on NS 2.
Thanking you,

Thanks, Matthias, yep the methods problem was that it was case sensitive and
i had forgotten that I changed it. I admit that it was stupid of me not to
realise this.
Are you  based in the Berlin TKN? Do you mind me using your package? :)



Im having problems that seem to be because of my version 2.30.
In 2004 december, Pepe Barbe had the same problem I currently have

*Despoina Triantafyllidou* replied that the problem was due to the version
"
the 802.11e patch is for ns-2.26.
under ns-2.27 may cause these problems...
"
As I am 2.30, why am i having similar problems?


 Here is the error I receive after running make:

 #warning This file includes at least one deprecated or antiquated header.

Subject: [ns] Can we get the TCP Congestion window values outputted in
 the trace which the simulator outputs
Message-ID: <dd2fb42bb5d6.466eb80a@usc.edu>

Hi All,
I am currently trying to analyze CONGESTION WINDOW VALUES FOR  CTCP by getting the normal TCP window values and summing it up with the delay component manually calculated (by a C++ program ) to get the congestion window values for Compund TCP.So I need to get the TCP congestion window values .The way I am doing it right now is recording the varaible "cwnd_" in a procedure called "Record" and calling it repeatedly at regular intervals of time.However I need to get unsampled values i.e., the congestion window values for each and every packet recorded in the trace as opposed to the congestion window values obtained by sampling at a regular interval.Can anyone plase tell me whether there is any way of extracting this information?I would really appreciate some help in this issue.

Thanks,
Vishnu Emmadi

Subject: [ns] Stitching of interdomain LSPs (label switched paths)
In-Reply-To: <56769.10.107.1.1.1180020904.squirrel@10.107.1.1>

Message-ID: <51787.10.107.1.1.1181722889.squirrel@10.107.1.1>

Hi,

For my purpose i need to stitch interdomain LSPs, explained below. I have
3 Autonomous systems say A B and C. I need to setup an LSP through A-B-C.
So within each AS i know the topology info so i use that to setup a LSP
within A, within B, and within C. Now i need to stich/join these LSPs, i.e
pass the label from the egress node of A to ingress node of B. How can i
do this.

The following code shows how i am finding a path within AS, and using it
to setup an explicitly routed LSP...

Tcl procedure
Agent/R2r instproc find_route {n1 n2} {
        global ns
        set routelogic [$ns get-routelogic]
        set c [concat $n1]
        set next [$routelogic lookup $n1 $n2]
        puts "$next"
        append c "_"
        append c $next
        while {$next != $n2} {
        set next [$routelogic lookup $next $n2]
        puts "$next"
        append c "_"
        append c $next
        }
        puts "$c"
        return $c
}

$c = 0_6_7_3_4_8_10_13_14

The following is C++ code snippet
char x[50];
Tcl& tcl = Tcl::instance();
sprintf(x, "%s find_route %d %d", name(), 0, 14);
tcl.eval(x);
const char* res = tcl.result();
sprintf(out, "[$n(%d) get-module MPLS] make-explicit-route 14 %s 3003
-1",sendx, res);
tcl.eval(out);


How can i find multiple paths, the above method only gives me the shortest
path within the AS.

Thank you for your patient reading.

Yours Sincerely,

Hello everybody,
let's suppose we want to encapsulate N small packets (each one with a certAin UDP header and its corresponding data) into a UDP bigger one. Is any agent of this kind already available in ns2?
 
Any tip would be greatly appreciated. Thank you very much in advance for your help.

Subject: [ns] Strange behaviour of TCPSink instvar "bytes_"
Message-ID: <466FBA62.7030607@sbox.tugraz.at>

Hi everybody,

I experienced a very odd problem. I want to output the number of bytes
received by a TCPSink agent at a specified time. This can be read by the
instance variable $bytes_.
Now if I call a procedure at the required point of time, which outputs
the nr of bytes, everything works fine. Like this:

    ...
    proc testproc {} {
        global tcp1
        puts stdout "Rx bytes (within testproc): [$tcp1 set bytes_]"
    }
    ...
    $ns at 1.0 testproc
    ...

But if I want to output this value directly (without a wrapping
procedure, the output is always 0! Like that:

    $ns at 1.0 "puts stdout \"Rx bytes (directly): [$tcp1 set bytes_]\""

How can that be?
I use ns-2.31. The complete code of a minimal example to reproduce the
problem is here:






######################### Example #############################

set ns [new Simulator]

proc testproc {} {
     global tcp1
     puts stdout "Rx bytes (within testproc): [$tcp1 set bytes_]"
}

set n0 [$ns node]

Ok, maybe the subject is a bit wrong - I just noticed that this problem 
is true for any instance variable. It can also be shown for example on 
"cwnd_" which is a variable of "Agent/TCP".

Dear All,

I am new to NS2 and presently going through "Marc Greis" tutorial. 
Presently on Chapter X Creating Wired-cum-Wireless and MobileIP 
Simulations in ns. It is written that

Note here that for wired-cum-wireless simulation traces may be generated 
for both wired and wireless domains. Both the traces are written into the 
same output file defined here as wireless2-out.tr. In order to 
differentiate wireless traces from wired ones, all wireless traces begin 
with "WL".

The output file that I got does not contain "WL". Is there something 
wrong, I am using NS - 2.28, on cygwin. Please help me, thanking you all 
in advance.

Warm Regards,

Hi everyone,

I tried to use "PacketQueue/Semantic" as the queue protocol in my
simulation, but segmentation fault occurs. 

Does anyone use "PacketQueue/Semantic" before? Did you have the same
problem?

Thank you very much,

Hi,

I never used that.  But there are ways to debug the code.

I use gdb and tcl-debug together to debug both the C++ and tcl code.
I found it very helpful.  See chapter 24 of `the manual' for how to
use them.

Subject: [ns] subclass of MobileNode
Message-ID: <79c5ea150706132140j22a4ed11pb28844c4cb108487@mail.gmail.com>

Hi,
I am trying to create a class which is a subclass of MobileNode. The part of
the tcl code I am using is

Class SubMobile -superclass Node/MobileNode

SubMobile instproc init {args} {
    ... class definitions
}

proc create-submobile-instance { id } {
    .......

    global SubMobile

    .......
    set node_($id) [new SubMobile]

}


The problem is when I try to create an instance of this class, I get this
error.

no such object
    (_o18 cmd line 1)
    invoked from within
"_o18 cmd target {}"
    invoked from within
"catch "$self cmd $args" ret"
    invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo

return ""
}
global errorInfo

    (procedure "new" line 3)

    (procedure "create-submobile-instance" line 8)
    invoked from within
"create-submobile-instance 1"
    (file "run-parms.tcl" line 378)


I believe this is because SubMobile does not have shadow in c++ but I don't
need code in c++ for this class because all this class does is initializing
some variables of the agent attached to this node. Do you have any
suggestions to overcome this problem?

thanks,
gesi

Hello NS Users, Sven, Matthias, hilal, and Pepe

I managed to get rid of the dh_da dh_sa problems that I mentioned in the
previous post.
BUT the rest of the make errors remain.
I am worried now. Because this makes me think that I need to use a different
version of NS, because Pete Barbe had a similar problem as seen at
http://mailman.isi.edu/pipermail/ns-users/2004-December/046055.html
Please tell me if I have to switch versions of NS. ???????
I do not know how to switch versions of NS. This is because I am new to NS.
Can someone please give me quick advice on how to switch versions. ????
Is their a quick way???

Thank you very much!

Here is my Make problem:

Subject: [ns] Strange behaviour of TCPSink instvar "bytes_"
Message-ID: <8372803c0706132322g66cf3cbcid124ee0ca04bd2a8@mail.gmail.com>

-
Hi,
I do not think that there is a "problem" with the variables per se,
but with the way that the TCL interpreter handles the command substitutions.

For example, when you invoke the command directly, i.e. with no
wrapping procedure, the NS scheduler schedules the event to occur
at time 1.0, but the event itself is actually to "puts stdout \"Rx bytes
(directly): 0\"".
What happens, is that when the interpreter comes across this command it
SUBSTITUTES
the part "[$tcp1 set bytes_]", with the actual value at that point (which is
always 0) and schedules
the command above to execute at point 1.0, which includes only the printout
and nothing more.

On the other hand, when you invoke it using a wrapper proc, the interpreter
does not do any substitutions
at the point of scheduling (i.e. $ns at 1.0 testproc) but simply schedules
the procedure to execute at point 1.0,
which in turn will substitute the correct value of bytes_ at time 1.0. Any
substitutions in this case are deliberately left
to the procedure from the interpreter.

This way of behavior, is for any command - scheduling - want - to -
substitute - with value processes. :-)

I hope that I have helped.

Subject: [ns] segmentation fault in strlen()
Message-ID: <25ffc6ed0706132340j6f5133f8h6f10bdadc87ff3f6@mail.gmail.com>

Hello, all:

When I run ns-2.29.3 with AODV-UU-0.8 ( not aodv), which has segmentation
fault at the end of transmission. For example,  I set up 60 nodes with 600
transmission, it will be broken with segmentation error.  I used gdb, and it
shows the phrase of strlen() .

I tested all of strlen() functions cross all of files containing this
function in each directory, but all of printed values show normal.

Can anyone give kindly help?  I haven't slept or eaten for almost 2 days,
which I got stucked by this fault.

Thanks in advance.

Hi, the EDCA model was released for ns-2.28. Just download this  
version of ns-2
(http://www.isi.edu/nsnam/dist/ns-allinone-2.28.tar.gz)
  and install it. Afterwards, you can apply the EDCA patch.

Best regards,

Subject: [ns] Header packet size
Message-ID: <963939.27778.qm@web23211.mail.ird.yahoo.com>

Hi, 
   
  I defined a new routing protocol for wireless sensor networks, and I implemented a new packets. I have the problem in the initialisation of header packet sizes. 
   
  Can you give me the technique used to calculate the header packet size?  
   
  Best Regards.

Subject: [ns] FHMIP and Ad-hoc routing protocols on NS-2.31
Message-ID: <33db0d640706140413y1e1ddf90g8575cd6305d6eba0@mail.gmail.com>

 Hi All

i patched fhmip patch on ns-2.31, before patching ad-hoc routing protocol
were working but after patching following message is coming

pankaj at pankaj:~/ns-2.31> ./ns ~/experiment/wrls-dsdv.tcl
num_nodes is set 3
warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl

highestAntennaZ_ = 1.5,  distCST_ = 129.2
SORTING LISTS ...DONE!
end simulation

None of the  ad-hoc routing protocol are working correctly. With all d-hoc
routing protocol same message " route not yet computed" is coming, not even
OLSR which i added to ns-2.31 after patching your given fhmip patch. I am
attaching tcl example files which were producing correct result before
patching fhmip patch.

fhmip patch for ns2.31
http://tagus.inesc-id.pt/~pestrela/ns2/files/ns2.31_fhmip.patch.gz

and  olsr patch for ns-2.31

how to solve this problem???,

thanks in advance

thanks and regards,
pankaj

Thanks , but I am a new user of NS. And I dont know how to switch versions.

Q1. Do I have to delete all my 2.30 files???????
Q2.my ns-allinone-2.30 folder is in my C:\cygwin\home\Simulator folder. Do I
need to delete it???
Q3. please could you tell me where the documentation about changing NS
versions is????
Q4. Is there a way to reverse changes, for instance by system restore?

sincere thanks guys

Subject: [ns] input a file in a packet
Message-ID: <8e345ee60706140656n53ee4fajd7ebe7804295cf55@mail.gmail.com>

Hello ns-users!
I really need your help and experience here.
I want to send a text-file (simple text) as payload in a packet.  Can it be
done?
What should i do?
Should i determine  new AppData such us MyData: public AppData or is there a
way just to put the text-file in the PacketData?
So far i just managed to put just a simple string.
I determined a simple MyApp:public Application and determine a "send(int
nbytes,AppData* data)" function in theUDP agent in order to send my string.
But can i send a file? and if so, could you please give me a hint?
I really need your help!  I spent days on this and still can't figure it
out...

Subject: [ns] Segmentation fault in PacketQueue/Semantic
Message-ID: <web-176339579@cgpsrv2.cis.mcmaster.ca>

Dear everyone,

I tried to do simulation with the semantic queue in ns2.26. I changed
nothing in ns2 original code. I set PacketQueue/Semantic in the tcl
script, but got the segmentation fault. By using gdb, i got the
following report for error:

Subject: [ns] how to send text-file as payload !!!
Message-ID: <8e345ee60706140236y7cd5508buf5a34b78f90041e6@mail.gmail.com>

Hello ns-users!
I really need your help and experience here.
I want to send a text-file (simple text) as payload in a packet.  Can it be
done?
What should i do?
Should i determine  new AppData such us MyData: public AppData or is there a
way just to put the text-file in the PacketData?
So far i just managed to put just a simple string.
I determined a simple MyApp:public Application and determine a "send(int
nbytes,AppData* data)" function in theUDP agent in order to send my string.
But can i send a file? and if so, could you please give me a hint?
I really need your help!  I spent days on this and still can't figure it
out...
Thank you!

Hello;
I am trying to use monitor for my wireless
simulations. In fact, I need a method to exect
simulations more rapidely. I know that in ns, monitor
how it is defined now, dosent work for a wireless
communication because it attachs the monitor to a link
and there are not physical links in a wireless
communication. A possible solution could be to attach
monitor to a queue directy, but I dont know where I
should chang exactly. Thanks for your help If you have
had the same problem before or you have solved the
problem of the long simulation time with another
approch,

 Hi,
  Sorry this is not a specific ns post, but if someone knows:)
  In the RFC 1889 the instantaneous jitter is given by:
J=J+(|(Rj-Sj)-(Ri-Si)|-J)/16
     I'm running a simulator and i have the packets sent and received
time. The problem is that i don't know how iperf gives the final
result, so i can't do the same and compare the real results with the
simulator results.

while iterating, if i do:
Jsum=J+Jsum, and then J_average=Jsum/(num_packets-1) the results
wouldn't be the same as iperf because  in a extract:

tiago at ksat67:~$ iperf -c 192.168.101.11 -u -b 500k -t 30
[  3]  0.0-10.0 sec    479 KBytes    393 Kbits/sec  9.184 ms    0/  334 (0%)
[  3] 10.0-20.0 sec    471 KBytes    386 Kbits/sec  11.203 ms   83/  411 (20%)
[  3] 20.0-30.0 sec    468 KBytes    383 Kbits/sec  10.314 ms   99/  425 (23%)
[  3]  0.0-32.5 sec  1.50 MBytes    388 Kbits/sec  11.123 ms  205/ 1277 (16%)

the value 11.123 ms is not the average of the another 3 above.

Subject: [ns] Modeling nodes as bottlenecks (CPU time)
Message-ID: <013b01c7aec2$4fbaa930$6501010a@schleppi>

Hi all,

Searching the NS archives did not shed much light on this
topic: is there a recommended procedure to model available computational
resources (CPU time) within NS nodes? 
I'm just wondering how one could model the following scenario in NS: a node
runs several distinct Agents. All Agents must provide some feedback on the
consumed CPU time and a node control unit delays incoming and/or outgoing
packets accordingly on congestion (meaning one queue+delay object upstream
and one downstream on any link).

>From an architectural point of view it's not clear to
me how Agents (the ultimate source to decide on required CPU processing time
for an application-specific packet that is sent or received) can change the
behavior of a classifier within the node structure or, even worse, control a
queue/delay object that is located upstreams or downstreams.

Any ideas/hints where to start searching? Are there any NS examples that
implement such behavior? Do you know of any work in this area?

thanks in advance,
br
Joachim

Do all UEs have the same movement ( although I see different trace files)?
How can we generate trace files for 5 users, 2 pedestrian and 2 vehicular
and 1of some other type ?

Message-ID: <b3817e5e0706180528o63d89ac7pa0cc853f008ce6b6@mail.gmail.com>

Hello everybody,

I am working on Mac protocol for wireless network. Let say I have node_(1)
with cbr traffic sending to node_(0). The cbr traffic will be like this:
start at 1.0, stop and 2.0, (re)start at 3.0 and stop again at 4.0 second.
My question is that: at 2.0, how Mac finds out that the traffic is indeed
done? For example, if node_(2) is a mobile phone, and cbr traffic is the
voice call, then at 1.0 it needs to set up the call and after 2.0 second it
needs to tear down the call.

If you know how to do this, please help me. I appreciate any help.

Hai.

Usually a MAC will not care about calls etc, it only handles individual 
data packets. In your terms, the MAC layer knows that there is no more 
traffic if its input buffer is empty. If you need a MAC layer that is 
aware of the duration of a call you need to implement some cross-layer 
interaction, i.e. the layer handling the voice connection needs to pass 
this information down to the MAC layer e.g. to (de)allocate ressources 
on the medium.

Subject: [ns] Mobile Node Positions and neighbor lists in MANET
Message-ID: <20070619050630.M73064@csse.unimelb.edu.au>

Hi all,

I have tried different ways to access the list of neighbors and their
locations including:

1- Node *nd = nd->get_node_by_address(addr());
    neighbor_list_node* nb = nd->neighbor_list_;
but nb is always NULL

2- bool Adian::IsNeighbor(int id)
{
    if(addr() == id)
         return false;
    Node *nd1 = nd1->get_node_by_address(addr());
    Node *nd2 = nd2->get_node_by_address(id);
    vector a(nd1->location()->X, nd1->location()->Y, nd1->location()->Z);
    vector b(nd2->location()->X, nd2->location()->Y, nd2->location()->Z);
    vector d = a - b;

    if (d.length() < 250)
         return true;
    return false;
}
but location() is always NULL and cause segment fault

3- int* neighborLstNode = God::instance()->GetNeighborList(addr());

I have added GetNeighborList(int) to the GOD but the result is NULL (segment
fault)
int* God::GetNeighborList(int id)
{
    //list<int> neighborlist;
    int neighborlist /*[] = new int*/ [nodes() + 1];
    int i = -1;
    neighborlist[0] = 0;

    while(mb_node[++i] != NULL)
    {
         if (i == id)
              continue;

         vector a(mb_node[i]->X(), mb_node[i]->Y(), mb_node[i]->Z());
         vector b(mb_node[id]->X(), mb_node[id]->Y(), mb_node[id]->Z());
         vector d = a - b;

         if (d.length() < RANGE)
         {
              //neighborlist.push_back(i);
              neighborlist[0]++;
              neighborlist[neighborlist[0]] = i;
         }
    }
}

Is there any solution to access to the location of mobile nodes or their
neighbors?

Message-ID: <46781921.9070704@gmx.de>

Hello everybody,

I'd like to simulate a Wimax scenario for which I need a physical layer for wimax with a lost  probability.
Therefor I have read the "WiMAX Channel - PHY Model in Network Simulator 2" paper, which introduce
a very sophisticated solution.

I spent hours to find the ns2 implementation, but unfortunately with no success.

Does anybody know where to find the sources of this or an other physical model for Wimax.
Also an other physical model for OFDM or OFDMA would really help me.

Thank you for your time

There is a variable called bug_fix_ in TcpAgent which is used to prevent
multipe entrance of fast retransmit. Its default value is true. I wonder
whether real TCP Reno implementation uses this strategy. I remember it's not
part of the Reno algorithm when I learn TCP/IP.

Subject: [ns] dynamic libraries in ns2: how to develop ns extensions
 withouth recompiling ns
Message-ID: <46791711.2080003@dei.unipd.it>


Hi all,

at the SIGNET lab, Dept. of Information Engineering, University of
Padova, Italy, we've developed a patch for ns2 which enables effective
use of dynamic libraries in ns2. We believe that the introduction of
this feature substantially improves the current way of developing
extensions to ns2. A list of the offered advantages is reported below:

* People can develop add-ons for ns2 (e.g. introducing new agents,
packet types, protocols) without having to modify the core simulator.

* New packet headers and types, as well as packet tracers, could be
defined to assist debugging, collection of statistics and inter-module
communication. These can also be loaded on demand according to user's needs.

* Dynamic libraries can be loaded at simulation time, with no need to
recompile the whole ns2 distribution or to keep different ns2 binaries.

* The installation of third-party ns2 extensions is made easier, thereby
facilitating their dissemination.

* Dynamic libraries will make life easier for lab technicians and
students. In fact, an official ns2 version can be installed by
administrators, and students can just build and use their preferred
extensions independently.

* ns2 will become more modular and scalable, while at the same time
preserving backwad compatibility.


We observe that dynamic libraries are natively supported in ns2 (see Tcl
load functionality). However, the set of functionalities which can be
accounted for by means of this approach is severely limited by the
intrinsic structure of the simulator. As an example, new packet types
and headers cannot be added to the code. In order to remove these
limitations, the patch we developed enables dynamic definition of packet
types, headers and their corresponding tracers.

Special care has been taken to ensure backward compatibility: the patch
has been designed in order not to interfere with the existing
functionalities in ns2. We have been testing this patch on different
linux systems since summer 2006, and so far we did not encounter any issue.

The patch is available at this location:
http://www.dei.unipd.it/~rossi/ns2-patch.html

Also, a detailed documentation of the modifications introduced by the
patch, as well as a tutorial for building ns extensions as dynamic
libraries, can be found at this location:
http://www.dei.unipd.it/~baldo/ns_dl_patch

Finally, we also provide a few sample modules to allow a straightforward
evaluation of the benefits provided by our patch. In particular, we
provide dynamic library versions of the UMTS implementation by the
EURANE project and of the TCP Veno implementation by NTU. The relative
packages can be found at this location:
http://www.dei.unipd.it/~baldo/ns_dl_patch/Sample_dynamic_ns_modules.html


Of course, any feedback on our proposal is welcome!


Regards,

Nicola

Dear all:

I was doing my final project in this summer. The main job for me is to do the simulation about the handover on the ns2 and implement a new handover decision policy. So far I still have no idea about where to start to add new functionalities, let alone about how to modidy the ns source files to add new handover policy. I have searched for this kind of things in the internet for a long time but have no luck. Now I only have one month left and be stuck in here. Could anyone who know this kind of things can give me some advice about how to start or recommand some materals which can provide information about how to add new fucntionality. Many thanks!!!!

  The network topology I have is:
 MobileNode(1.0.1)---~---BaseStation(1.0.0)---FixedNode(0.0.0)
  Is sent a cbr UDP flow from the Mobile Node to the Fixed Node

  Following the packet "-Pi 63", i got the lines related with it:
s -t 25.151200000 -Hs 2 -Hd -2 -Ni 2  -Nl AGT -Nw --- -Ma 0 -Md 0 -Ms

- 25.563348 1 0 cbr 1492 ------- 0 1.0.1.0 0.0.0.0 63 70

-The packet is sent from the -Is  4194305.0 to the -Id 0.0, that
should correspond to the Address.Port of the Mobile Node and
FixedNode, they remain the same.
-First I can conclude that the packet is sent by the entity AGT node
-Ni 2 or -Hs 2, that is the Mobile Node,  to the Hop destination = -2,
is this a broadcast?
-And at the same time is received from the network layer  RTR, a
broadcast from the node -Hs -2. Which station receives the broadcast,
the BS or the MN? The confusion is, a 'r' means that the source Hs 2
received the packet? So what means the Hd -2?
-Then also at the same time a RTR packet is forward from the MN ID to
the  -Hd 4194304, that should be the BS address, and after the data is
sent  from the MN to the BS several times (-Il 546, -Il 828, -Il 142).
In the end the data is received by the node ID -Hs 1, from the -Hd
4194304?, this means that the BS has two entities, the Mac Address
that gives all the frames simultaneously (that's the entire packet) to
the Application layer with the Node id=1?
And in the end the packet is received by the -Hs 1, that is the node
ID of the BS, and then given to the FixedNode ID "1 0 cbr".

Kindly, Tiago Junqueira

Subject: [ns] tracegraph problem
Message-ID: <1217925b0706210857u749de0fcpe092d051e8a470a0@mail.gmail.com>

Hi all,

I get a problem when trying to launch trgraph.
I have downloaded tracegraph into dir /<path>/tracegraph202.
I Created tracegraph202/mgl dir for the mglinstaller, i run the installer
and put /<path>/tracegraph202/mgl/bin/sol2 into my LD_LIBRARY_PATH.
When i type ./trgraph i get the following error:
./trgraph: error while loading shared libraries: .../sol2/libmwsgl.so: ELF
file data encoding not little-endian.
I have checked my php.ini file in order to load the correct file multiple
times.
when i type
php trgraph
i get the following:
"Some warnings"
PHP Parse error: syntax error, unexpected T_STRING in trgraph on line 2280
I have no idea on how to display this file (it's a binary isn't it?).

I only want to launch trgraph!
Am i doing something wrong? Any ideas?

Tnx

Dimitris

Message-ID: <8e20d47b0706211117r14b003a1ka7739099f6f9f012@mail.gmail.com>

hello all,
I found this on Wikipedia:
for a given 2 ms frame, data may be sent to a number of users
simultaneously, using different channelisation code. The maximum number of
users to receive data on a given 2 ms frame is determined by the number of
allocated channelisation codes.
( http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access ).

Does EURANE implement this ? If not, what is then the channel access method
used ( am sure it is not CDMA )

Thank you in advance,

TCP's protocol radius: the distance where timers prevent communication
Lloyd Wood, Cathryn Peoples, Gerard Parr, Bryan Scotney, Adrian Moore.
Peer-reviewed conference paper, to appear at the International Workshop on Space and Satellite Communications (IWSSC '07), Salzburg, Austria, September 2007.

We examine how the design of the Transmission Control Protocol (TCP) implicitly presumes a limited range of path delays and distances between communicating endpoints.

As well as showing the limits to TCP's communication range, we also show that ns's SYN/ACK exchange is not realistic compared to implementations, as it repeats sending SYNs infinitely. This seems to have encouraged people tweaking TCP for long distances in the past -- they don't realise that the SYN/ACK exchange limit in all implementations sets a hard limit on distance.

Subject: [ns] Memory leak in Tdma Mac !?
Message-ID: <b3817e5e0706211447y252b37e6s803651a51e190d15@mail.gmail.com>

Hi everybody,

I am not sure but I think I found a bug in ns2. Specifically, it is Mac/Tdma
protocol for wireless network. In the example ~/tcl/ex/wireless.tcl, there
are 50 mobile nodes running 802.11 in 1000 seconds. I tried increasing
simulation time to 10000 seconds, and it's running fine. During execution, I
observed that ns-2 consumed around 80% CPU and 4.5% memory steadily.
Interestingly enough, when I changed the Mac protocol from 802.11 to
Mac/Tdma, keeping all other parameters the same, it crashed at around 7000
seconds simulation time. For comparison, I observed that in this case ns-2
took 90% CPU (which is fine), but also consumed a crazy amound of 90% memory
(my computer has 2GB RAM, this means ns2 took almost 1.8GB), increasing very
fast from 5% to 15%, 30%, ...etc...  I tried this with different machines,
even with a Dell server with strong computation and memory capacity, yet the
result was the same.

And the bug I got is this:
------------------------------------------------
terminate called after throwing an instance of 'std::bad_alloc'
  what():  St9bad_alloc
------------------------------------------------

I have been trying to find the reason, but nothing is found yet. My guess is
that Tdma allocates data for packets, but doesn't free it properly after
send/receive, which leads to memory leak. Indeed, at the sending site, the
function sendHandler(Event *e) does free the packet, and at the receive end,
the function recvHandler() sends the packet to upper level. Thus, I haven't
seen anything unreasonable here. I was trying to install and use dmalloc,
but compiling ns2 with dmalloc support gave me errors, so I gave up that
approach.

Anybody knows the reason/solution please tell me. Thanks.

Hai.

Subject: [ns] NRTE: MAC - Routing dialogue
Message-ID: <FBCMMO03MGN7OsdtxxJ000080d7@FBCMMO03.fbc.local>

Hi everybody.
I've a problem with the MAC protocol I'm using, that I developed (it wasn't inside ns)...
when node mobility is 0.0, everything works... But when I set node mobility to a value greater then 0.0, the Routing Protocol (AODV) can't find a route any more. That is: everything works till a node starts to move from its initial position. The error in trace file is NRTE!
Perhaps I make some mistakes, in developing MAC, perhaps something necessary to the dialogue MAC-ROUTING...
Can somebody help me? What are, in general sense, the necessarious steps to make everything work right between MAC & Routing levels?

I have execute a process given on  : http://www.csse.monash.edu.au/%7Eklangjai/index_files/Page1387.htm
  1-dowload  ns-2.30 allinone (from ns) and 2.1b8-mcast (from monarch)
  2-put 2.1b8-mcast inside ns-allinone folder and start copying following folders over to ns-2.30 folder; odmrp, admr, WORKS, SCRIPTS, RESULTS, TRACES, routing_agent, unicast_agent, movement-scenario, mcast_communication-scenarios
.and files ns-packet.tcl, ns-cmu-trace.tcl, packet.h, cum-trace.h/cc, wireless-phy.h/cc, ns-mobinode.tcl, ns-default.tcl
  3-copy the Makefile.in from ns-2.1b8-mcast to ns-2.1b8
  4-./configure, make clean, make
  After the make I have the message :

Hello to all!
I would like to ask for some advice. I want to have on its node a database
which will contain some information about the node, the other nodes etc.
What i  would like to ask is, what do you suggest would be the ideal choice
as far as the sql communication through c++.
I am working on linux openSUSE, so what should i do?
Should i install sql/mysql ?
Please give me your advice!

Hello Matthias!
 Thank you once again for your reply.
The truth is that i don't know exactly how sql nad mysql work., but i am
willing to...
I want to have a simple database on each node (very simple). Lets say that
we have 10 nodes with a simple database on each node. Each database will
include informations. These informations will be retrieved by queries which
i intend to store in packets.
So when a packet is sent to a desired node, then it will reach the
application layer and somehow will poll the query to the database that
belongs to the node.
Do i have to simulate sql server at each node?
Please help me.

Subject: [ns] how does monitor-queue works?
Message-ID: <b396a8130706240224j3bb41773j3d549da180e97ba3@mail.gmail.com>

Dear NS users

I simulated a simple network consisting of 2 sources and 3 links, using
ns2.29.
In this simulation I want to monitor the queue between nodes n3 and n4.
I used the following command to do this:
set qmon [$ns monitor-queue $n3 $n4 [open qm.out w] 0.1];
[$ns link $n3 $n4] queue-sample-timeout;
At the end of simulation "qm.out" is created.
The 4'Th column must be the queue size in bytes and the 5'Th column must be
queue size in packets.
These variables must be integer variable, whereas related columns in "qm.out"
are real value numbers.
I want to know is this normal or it is a bug.

How can I collect the queue size correctly, if it is a bug? Or how can one
interpret this (expected integer value data (queue_size) are real value data
in practice).

Some lines of "qm.out" are presented here.

Hi all,
   
   
  Please i need for your help. To estimate a avalable bandwidth  i need to compute a basy or idle time of a node in a periode of time. Please how can i compute this idle/busy time under mac-802_11.cc
   
  Thanks for your Help

 Hi all,

i am trying to find out how does NS choose one path among multiple available
paths for sending data from a source to a destination???
whether it decides path using any shortest path algorithm or any other
one???
and on what basis it decides certain path ????
what is the right way to find this???

need help

Subject: [ns] Receive Wireless Frames thresholds
Message-ID: <4bb1b4060706251922u3345ae29lcac7dc1a8559c786@mail.gmail.com>

	Hi people,

	I'm not understanding how is processed an incoming wireless packet. I
setted the following thresholds:
	Phy/WirelessPhy set RXThresh_ 630e-15
	Phy/WirelessPhy set CSThresh_ 630e-15

	I'm using the FreeSpace model, and a distance of 880 m with Gr=50 and Gt=25.
If I run the script for a Pt_ = 0.0158 W (12 dBm), the power received
using the Friis formula or the result printed by the function i get:
	OFDM phy receiving packet with mod=0 and cp=0.250000
	0.031842: d: 880.000000, Pr: 1.199811e-09
	
	But if I run the script for Pt= 0.01 W (10 dBm), there is no packet
received, and Pr is not printed, but it should be more or less
7.2e-10.
	Why the value is higher than the thresholds, and the frames are not accepted?
	(I don't know if this is important,but i'm simulating WiMAX with the
NIST package)

	Another question is, the CSThresg_ is the collision Threshold, is it
important when there is only one cbr flow from one station to the
mobile node? There should be no collisions?
	When the signal strength of the frame is between RxThresh_ and
CSThresh_ , it will be tagged as corrupted, and there is a probability
of reception in the MAC layer or not?

   thanks in advance

Subject: [ns] emulate network (hope to get an answer)
Message-ID: <BAY137-F3176122CEF53B039D19974D90B0@phx.gbl>

i want to build a scenrio when the user have problem connecting to the 
internet
due to miss configured dns or network problem .

my real network  topology is

A---->B----->C

i already manage to capture icmp packets sent from A to B and inject them to 
the simulated network.
bu i wonder if it is possible to avoide the simulated network? i mean to 
generate ns2 trace file
completely based on whatever C capture
for example :
C caputre sent packets
C capture recv packets
so on the trace fill i will this result without any simulated network ?

the reason is that i want to avoid any protocol depandency.


please, can anyone guid me somewhere?

Thnx

Subject: [ns] A simple scenario using a Module-based Wireless Node (MW-Node)
Message-ID: <KJEMLIMJDELALOILGGAAEEHPCAAA.andrey.krendzel@cttc.es>

Dear NS-2 users,

I am dealing with A Module-based Wireless Node (MW-Node) for ns-2.30
supporting for multiple interfaces/multiple channels:
http://www.q2s.ntnu.no/~paquerea/ns.html
<http://www.q2s.ntnu.no/~paquerea/ns.html>

Firstly I want to consider the simple scenario based on the presented
example: http://www.q2s.ntnu.no/~paquerea/ns/mwnode-ex
<http://www.q2s.ntnu.no/~paquerea/ns/mwnode-ex>  in order to understand how
it works.
So, I have 3 wireless fixed nodes located in a line (see the diagram below).
A node 0 has one wireless interface that operates on channel 0, a node 1 has
two interfaces that operate on separated channels 0 and 1, and node 1 has
one interface on channel 1. Four CBR flows are sent at different time from
the node 0 to the node 1, from the node 2 to 1, from the node 0 to 2, and
from the node 2 to node 0 correspondingly. When I run NAM three of the four
CBR flows are successful excluding the CBR flow from the node 0 to the node
2. In other words, there is a problem of interface switching in the node 1.
If I change the channels 0 and 1 by places for the node 1 in the script the
CBR flow from the node 0 to the node 2 is successful, but then the node 2
cannot send packets to the node 0. Could you please indicate me where there
is an error in the script?

Thanks in advance.

Regards,

Andrey Krendzel

Hi,

 The transmission power of Pt_=0.01 W, works if i reduce the thresholds from
	Phy/WirelessPhy set RXThresh_ 630e-15
	Phy/WirelessPhy set CSThresh_ 630e-15
to, for example:
	Phy/WirelessPhy set RXThresh_ 1e-15
	Phy/WirelessPhy set CSThresh_ 1e-15

 My question is, there must be another variable that i'm forgetting,
because for 0.01 W, the received power should be 7.2e-10 >> 6.30e-13,
I mean 7.2e-10/6.30e-13=1142 W/W, or 30.6 dB. I would like to know
where is that 30.6 dB implemented.
	Thanks for your attention, kindly Tiago Junqueira

Subject: [ns] Multirate 802.11 implementation is now available
Message-ID: <200706261232.06328.maguolof@dei.unipd.it>

Hi all,
I would like to announce the publication of a new 802.11 that we
developed at the SIGNET lab, University of Padova, Department of
Information Engineering (DEI), downloadable  at

http://www.dei.unipd.it/wdyn/?IDsezione=5090

This 802.11 implementation, named dei80211mr, permits the simulation of rate 
adaptation algorithm (in the distribution an implementation of ARF  is already 
included) with an enhanced physical layer with respect to those 
in the ns distribution. In particular:

- support for multiple PHY modes is included; in particolar,
  dei80211mr supports simulation of the different transmission rates,
  modulation and coding schemes defined in the IEEE802.11b/g standards.

- a SINR-based packet level error model is introduced:
  + the RX Threshold variable which was used in the 802.11
    implementation included in standard NS to determine successful
    receptions has been removed. Instead, Packet Error Rate (PER) is
    used to determine random packet losses.
  + PER is calculated using pre-determined curves (PER
    vs SINR and packet size); the curves can be specified by the user
    via TCL. Some default curves for both 802.11g and 802.11b are
    provided.
  + SINR is calculated using received signal strength, noise and
    interference
  + interference is calculated using a gaussian model to account for
    all transmissions which happen simultaneously to the one which is
    considered for reception
  + noise power is set via TCL

- the capture model, i.e. the determination of whether a packet can be
  received when there are other concurrent transmissions are
  simultaneously ogoing, is now embedded in the above mentioned
  interference model (no more Capture Threshold).

- Some well-known bugs of the 802.11 implementation in NS have been
  resolved. With reference to [1], we solved the following bugs:
  + direct access denial
  + random backoff time
  + capture model (note: this is different from the point above since,
    as per the description in [1], it is actually a synchronization
    issue)

- In the wireless channel, the affected nodes distance is no more
  determined using the CS threshold, but we used a fixed value in
  meters (distInterference_) which can be set at the beginning of the
  simulation. The reason is that, since we use a gaussian interference
  model, nodes well below the CS threshold often still provide a
  non-negligible contribution to interference. The default value for
  the affected nodes distance (distInterference_) is very
  conservative, so that all nodes are considered for interference
  calculation. This default value therefore yields accurate but
  computationally intensive simulations. The value can be adjusted via
  TCL to achieve different trade-offs between computational load and
  simulation accuracy.

- Several useful 802.11 MAC MIB counters described in [3], Annex D, have 
  been added to the MACMIB C++ class

- dei80211mr can be used within the classical ns-2 MobileNode



dei80211mr is distributed as a dynamic library using the Dynamic Library
patch [2]. Thanks to the functionalities introduced by this patch,
dei80211mr can be used with different versions of ns2. We have tested it
with ns-2.29 and ns-2.31, and we expect it to work with future ns2
releases as well.

Message-ID: <62736.137.194.8.245.1182952709.squirrel@webmail.enst.fr>


Hello,

I am a new ns user i am trying to simulate a wireless topology using OLSR
as a routing protocol. I need to simulate a link failure for a short
period of time to study the reactions of OLSR to the failure.
while searching through nsDOC and the user list i found that the only way
to simulate a link or node failure would be using the rtmodel-at command
which i added to my Tcl script.
I first tried the $ns rtmodel-at 3.9 down $node_(3) $node_(5) command in a
wired topology simulating the failure of the link between node 3 and node
5 which worked perfectly.
I also tried the $ns rtmodel-at 3.9 down $node_(3) to simulate the failure
of the node 3 in a wired topology which worked as well.

I tried these procedures in my wireless topology network

Link failure simulation:
$ns rtmodel-at 3.9 down $node_(3) $node_(5) wouldnt work and returned an
error message which i supposed was due to the absence of links explicitly
created between the nodes (like it would be in the wired topology)since
the medium was radio.

Node failure simulation:
$ns rtmodel-at 3.9 down $node_(3) did not return any error and the
simulation worked correctly but i noticed when analyzing the trace files
that node 3 was still up and active in the network.

Could anyone tell me what the problem is and the command i need to use to
simulate a node or even a link failure ( if possible ) in a wireless
scenario?

Any help or tips would be greatly appreciated,
Thank you,

Our module works exactly  as you have described: when a packet is received, it 
begins to record the interference profile perceived by the radio. The 
Gaussian model hypothesis permits to consider the interference power as  the 
sum of all the packets transmission power sensed in the medium.

The scene is three wireless nodes:

Subject: [ns] dynamic libraries in ns2: how to develop ns extensions
    withouth recompiling ns
To: ns-users at ISI.EDU
Message-ID: <46791711.2080003 at dei.unipd.it>
Content-Type: text/plain; charset=ISO-8859-1


Hi all,

at the SIGNET lab, Dept. of Information Engineering, University of
Padova, Italy, we've developed a patch for ns2 which enables effective
use of dynamic libraries in ns2. We believe that the introduction of
this feature substantially improves the current way of developing
extensions to ns2. A list of the offered advantages is reported below:

* People can develop add-ons for ns2 (e.g. introducing new agents,
packet types, protocols) without having to modify the core simulator.

* New packet headers and types, as well as packet tracers, could be
defined to assist debugging, collection of statistics and inter-module
communication. These can also be loaded on demand according to user's needs.

* Dynamic libraries can be loaded at simulation time, with no need to
recompile the whole ns2 distribution or to keep different ns2 binaries.

* The installation of third-party ns2 extensions is made easier, thereby
facilitating their dissemination.

* Dynamic libraries will make life easier for lab technicians and
students. In fact, an official ns2 version can be installed by
administrators, and students can just build and use their preferred
extensions independently.

* ns2 will become more modular and scalable, while at the same time
preserving backwad compatibility.


We observe that dynamic libraries are natively supported in ns2 (see Tcl
load functionality). However, the set of functionalities which can be
accounted for by means of this approach is severely limited by the
intrinsic structure of the simulator. As an example, new packet types
and headers cannot be added to the code. In order to remove these
limitations, the patch we developed enables dynamic definition of packet
types, headers and their corresponding tracers.

Special care has been taken to ensure backward compatibility: the patch
has been designed in order not to interfere with the existing
functionalities in ns2. We have been testing this patch on different
linux systems since summer 2006, and so far we did not encounter any issue.

The patch is available at this location:
http://www.dei.unipd.it/~rossi/ns2-patch.html

Also, a detailed documentation of the modifications introduced by the
patch, as well as a tutorial for building ns extensions as dynamic
libraries, can be found at this location:
http://www.dei.unipd.it/~baldo/ns_dl_patch

Finally, we also provide a few sample modules to allow a straightforward
evaluation of the benefits provided by our patch. In particular, we
provide dynamic library versions of the UMTS implementation by the
EURANE project and of the TCP Veno implementation by NTU. The relative
packages can be found at this location:
http://www.dei.unipd.it/~baldo/ns_dl_patch/Sample_dynamic_ns_modules.html


Of course, any feedback on our proposal is welcome!


Regards,

Nicola

Dear all:

I was doing my final project in this summer. The main job for me is to do the simulation about the handover on the ns2 and implement a new handover decision policy. So far I still have no idea about where to start to add new functionalities, let alone about how to modidy the ns source files to add new handover policy. I have searched for this kind of things in the internet for a long time but have no luck. Now I only have one month left and be stuck in here. Could anyone who know this kind of things can give me some advice about how to start or recommand some materals which can provide information about how to add new fucntionality. Many thanks!!!!

Subject: [ns] how to set the number of sources (Amita Singh)
Message-ID: <186397.47404.qm@web31705.mail.mud.yahoo.com>

The numbers of sources (sources CBR traffic) is set under a file name stdest, that you find in ns. This files are in a folder named "indep-utils" in ns-2.30 folder. You modify this file using the comand: 
./setdest [-n num_of_nodes] [-p pausetime] [-s maxspeed] [-t simtime] \
      [-x maxx] [-y maxy] > [outdir/movement-file]
For example: ./setdest -n 20 -p 2.0 -s 10.0 -t 200 -x 500 -y 500 > scen-20-test
and the scen-20-test is an output file that you can use in a wireleess.tcl for example

Hi all,
As I have seen that in many simulation studies of ad hoc networks using ns2 variable number of sources are being considered, but can anyone tell me how to set the number of sources.

Thanks in advance
Amita

Dear Charles,

I have managed to solve this problem but have run into a new one.

When I "make" ns, it stops with some error in the sctp.cc as follows:

=================================================
In file included from ./common/ip.h:41,
                 from sctp/sctp.cc:41:
./config.h:103:1: warning: "STRTOI64_FMTSTR" redefined
In file included from /usr/local/include/tclcl.h:47,
                 from ./config.h:60,
                 from ./common/ip.h:41,
                 from sctp/sctp.cc:41:
/usr/local/include/tclcl-config.h:37:1: warning: this is the location of the 
previous definition
sctp/sctp.cc: In destructor ‘virtual SctpAgent::~SctpAgent()’:
sctp/sctp.cc:155: error: invalid lvalue in assignment
make: *** [sctp/sctp.o] Error 1
===========================================================


I think that this is some coding error as it is in the destructor. I am 
hoping that there would be a patch for this problem.

In the meanwhile I am trying to download ns2 source separately from the 
allinone tar. Was having similar coding error issue in the tcl that came 
with the allinone, and when i tried with a separate source it worked.

Thank you,

Abid Ghufran.

Hello Abid Ghufran,

Generally, lower version of ns2 will require patching while installing on 
higher version of linux.

So try to find the Fedora Core-5 patch for ns 2.27 and apply it before 
compiling it.

Before that, While installing linux, select all packages related with X.(try 
full install). It will avoid such library related errors.


Post  your specific quires in our forum at  http://projectguideline.com/ is
Very much appreciated

Subject: [ns] Need Help for TCPAgent::rtt_update()
Message-ID: <DlkrrSG5.1182961244.6879500.teerawat@localhost>


Hi,

I have a question in regards to function rtt_update of class TcpAgent.
Here is the code:


================= BEGIN CODE =================================
void TcpAgent::rtt_update(double tao)
{
	...
		double sendtime = now - tao;
		sendtime += boot_time_;
		double tickoff = fmod(sendtime, tcp_tick_);
		printf("sendtime = %2.4f, boot_time_ = %2.4f, tickoff =
%2.4f\n",sendtime,boot_time_,tickoff);
		t_rtt_ = int((tao + tickoff) / tcp_tick_);
	}
...
}
================= END CODE =================================
Why can't we use 'tao' as an RTT sample? Why do we have to consider
"boot_time_" ?  It seems like "tickoff" is the offset which helps
line up tao to the end of "tcp_tick" after "boot_time_" is
considered. But why do we need to consider "boot_time_".

Thanks a lot.
Teerawat

In a wireless scenario you do not have links, so you cannot shut them 
down. One option is to simply move a node out of the transmission range 
of another. This may become difficult for a large number of nodes. You 
could also extend the node to implement something like a MAC filter so 
that a node simply ignores messages from individual sources. But im not 
aware of any such solution currently existing. You could also modify the 
propagation model to create very specific transmission failures, e.g. 
drop all packets from a specific node (node failure).

Hello Daniel,

Thank you, but you didnt say why the solution of simulating a complete
node failure wouldn't work.
I understand that shutting down links is not an option since links don't
exist like i supposed but shouldn't i be able to shut down a node in
wireless like i do in wired scenarios figures?

hi all,

 I am  trying to implement ODMRP (Monarch extension ns-2.1b8) on ns-2.30. I have ported the code of ns-2.1b8  to 2.29 My  odmrp code is complied fine. but when i am using the tcl script which is  there with the ns-2.1b8 for running the ODMRP on a particular scenerio the
 error in the <odmrp.tcl > file is as:

 I think there is any problem in passing the arguments to the "eval "
 procedure for the interface to the node. I have tried hard to find where the
 eval is defined, but enable to find. please if any one has faced the same
 problem with this code please help me.I needit urgently.
 Thanks,

Subject: [ns] Receive Wireless Frames thresholds (Tiago Junqueira)
Message-ID: <615696.12782.qm@web15913.mail.cnb.yahoo.com>

Hi,
   
  Why I always get 'cannot post' message. That considerably affects my passion.  :>
   
  In my experience, Pt_ seems to be the max transmission power and relate to something that count the affected neighbors.
  So if we change Pt_ directly, some nodes will not receive packets as we thought.
  What I do is using a new variable named txPower to replace the Pt_ in sendDown() function.
  Then you can change the transmission power 'txPower' from 0 to max 'Pt_', but Pt_ is still the max transmission power.
  By this way, you will not decrease the number of affected neighbors.
   
  When the signal strength of the frame is between RxThresh_ and
CSThresh_ , it will be tagged as corrupted, and it will be dropped in implemention of mac-802_11.cc.
  Generally, if the receiving strength of a packet is under the RxThresh_, it will be considered as cannot be interpreted correctly with too much error bits.
  Some other implementions might be changed to according to BER.
   
  Hopes helpful.

I also want to know whether there is any simple way to shut down nodes.
  I use "$ns_ node-config -IncomingErrProc UniformErr" to assign nodes different link loss.
  But I have to add a "kill-node" command to shut down nodes.

can anyone help me with this output ? and please could someone explain the
difference between the

$ns_ at 60.0 "$node_(0) off"

and

$ns_ rtmodel-at 60.0 down $node_(0)

is the 1st one only available when using an energy model? and how come the
second one has no effect on wireless nodes

PS: i am using a 802.11 model

any help would be greatly appreciated

$ns_ at 60.0 "$node_(0) off" now works but i still can see packets being
sent (and received) from node 0 after it was shutdown in the trace file...

Any ideas?

Message-ID: <BAY105-F20D1D6E744226F917619F3A0090@phx.gbl>

Dear All,


I intend to intall pdns and for that purpose am installing/configuring 
ns2-2.27 on FC-5.

When I run make I get a lot of errors in the SCTP.h, SCTP.cc, Queue.h and 
various other files. They seem like syntax errors, as they refer to 
destructors, invalid lvalues, and invalid (class) namespace specifiers.

Is there any patch that I could use for ns2-2.27?


Thank you,

Abid Ghufran.

You can try to set the coordinates of the nodes to large values.
$node set X_ 10000
$node set Y_ 10000

I haven't done this before, hope it works.

You have to declare your agent as a variable of another class. Initiate
the agent variable at the constructor of that class. Then you can call
public function of your Agent class through that variable.

See class Timer for example.

Subject: [ns] Question about MAC level packet scheduling in NS-2
Message-ID: <op.tuobv0m2xsrog2@vt-g7ktwagnde3r>

Hi,

I am a distributed systems researcher and I am relatively new to NS-2. I
want to do some fancy MAC level packet scheduling in order to guarantee
end-to-end timeliness on ad hoc networks. I read the documentation and
looked at the source code but I am not certain were to begin. As far as I
can tell, the interface queue is implemented in priqueue.cc and priqueue.h
where routing protocol packets are placed at the head of the queue. The
link layer (ll.cc and ll.h) contains a pointer (ifq) to the base queue
class (Queue.cc and Queue.h). In order to implement my scheduling policy,
I am going to derive a class from Queue. How do I include this new queue
class into my new MAC protocol? Once again, sorry if this is a stupid
question but I am new to NS-2.

Thanks!
Fahmy

This could be a problem of defining the simulated nodes. I faced with the same problem because I didn't modify the number of nodes in the file.tcl. I had a wirelles.tcl where I had to put other files like cbrgen, stdest and in the file.tcl I made the mistake not to modify the number of node simulated. 
    This I think is the problem.

Subject: [ns] New release of iNSpect available! A Visualization Tool for
 MANET Simulations with ns-2
Message-ID: <4684E724.1030803@igd.fraunhofer.de>

Dear ns-2 users,

a new release of iNSpect is available at
http://www.igd.fraunhofer.de/igd-a8/en/projects/mobsec/inspect/. The
focus of the new release was a major architectural change to improve the
flexibility, the robustness and the efficiency of the tool.

iNSpect is a Visualization Tool for MANET Simulations with ns-2. It
takes log files (so called trace files) created by the common open
source network simulator ns2 and creates a visual presentation of the
simulation data.

A user can play a simulation (continuously move along the simulation
time axis), halt it, jump to a specific simulation time and activate or
deactivate more detailed data presentation features. iNSpect provides
also the means to take screenshots or record movies. These movies can be
shown using common media players independently of iNSpect and are
therefore useful for presentations.

The focus of iNSpect's visualization is to present movement and data
transaction of mobile nodes in MANETs in a clearer way then this has
been possible with former tools.

Best regards,
Peter Ebinger and Fatih Gey


------------------------------------------------------------------------

Background and Application Areas

iNSpect was originally written by Neil Mushell and Stuart Kurkowski at
Toilers Research Group at the Colorado School of Mines (USA) and was
published in 2004. In April 2005 iNSpect version 3.3 has been released.
Subsequent development began by Fatih Gey and Peter Ebinger at the
Security Technology Department of the Fraunhofer Institute for Computer
Graphics Research IGD in Darmstadt (Germany). In late 2005 the
development of iNSpect at the Colorado School of Mines by Neil Mushell
and Stuart Kurkowski was stopped.

The focus of the current developments is major architectural changes to
improve the flexibility, the robustness and the efficiency of the tool.
Due to these changes, several modules had to be rewritten from scratch
with the result, that the current version actually has less features
than former versions. However, as a result the new iNSpect version is
easily extendable and offers a wide range of possibilities for
attachments and for adding new features or expanding the existing ones.
Features that are missing at the moment are not meant to be abandoned;
they will probably be re-implemented in future releases.


Documentation

There is a User Manual and a Developers Guide available for iNSpect.
- User Manual: The user manual describes how to configure and use
iNSpect. The manual presents all functions and features that are
currently available.
[http://www.igd.fraunhofer.de/igd-a8/en/projects/mobsec/inspect/iNSpect_UserManual.pdf]
- Developers Guide: The developers guide describes the internals of
iNSpect and how it can be extended.
[http://www.igd.fraunhofer.de/igd-a8/en/projects/mobsec/inspect/iNSpect_DevelopersGuide.pdf]

Download

iNSpect was implemented and compiled using gcc compiler version 4.0 and
below, so far it does not work with any compiler version newer than that.

Subject: [ns] Mobility Models
Message-ID: <11366754.post@talk.nabble.com>


Hello everybody.I am a new user in NS2 and I will try to implement some
mobility models in NS2 and implement.As I have searched around I think that
it is quite difficult in a short period to implement one on my own so I will
try to test some already built ones.Cause I am a new user I would like to
ask how difficult it will be to get familiar with NS2 in order to use some
mobility models?Is it easy to use the existing ones and experiment on
them?How complicated is the code of such models and how easy it is to test
on different senarios?Thanks for the post and I hope that I will be able to
help somebody else when I get used to the program.Please If anybody know I
would be grateful to help me even if the questions look sily.Thanks again!:)

Hi,

I didnt see the message, it wasnt sent to my mail, so i'll answer just now.
Why you dont config like in the example datarate.tcl, first  all the options
for the configuration of the wireless node that will after be created, and
then just change the different parameters for the MN or SS. If you can run
that example without receiving an error message is because your sintax is
not correct probably. But also probably you already solved that problem:).
kindly, Tiago Junqueira

Hello,

To get start with mobility models you can start with this file (assume ns is
the directory of your ns2): ns/indep-utils/cmu-scen-gen/setdest.cc. This is
an independent tool, not really related to ns2, but it is an aid for running
simulation on wireless networks. This code in fact generates a mobility
scenerio using Random Waypoint mobility model. You can provide a number of
nodes, speed, pause time, duration of the simulation... After this, you will
have a scenario file ready to run with your ns2 simulation.  Some quick
examples you might want to have a look are at this folder: ns/tcl/ex/

The code for generating a mobility model is indeed not very complicated as
you might have a look at setdest.cc. From this, you can modify as much as
you want to have your own mobility model, for example Random Walk, Random
Smooth (for independent mobility) or other group mobility.

Hope this might help.

Hai.

Subject: [ns] New release of iNSpect available! A Visualization Tool for
	MANET Simulations with ns-2
Message-ID: <A42131F1-238D-4FFD-BBC9-ACE5B958B8DC@mines.edu>


For those unaware of the iNSpect software being discussed here,  
please see:
	http://toilers.mines.edu/Public/NsInspect

Peter and Fatih have done a nice job of re-implementing parts of our  
iNSpect tool (version 3.3). While their iNSPect tool does not include  
all the features that we offer with our iNSPect tool, they have  
definitely improved upon our original code structure.

I do, however, want to clarify a few items on this "new release of  
iNSpect".

- While it is true that development of new features in iNSpect is not  
on-going at the Colorado School of Mines, we do provide maintenance  
and support for our iNSpect software.

- Peter and Fatih state that "iNSpect was implemented and compiled  
using gcc compiler version 4.0 and below, so far it does not work  
with any compiler version newer than that." This is true of our  
version 3.3 of iNSpect and Peter/Fatih's version of iNSpect. We have  
recently released version 3.4 of iNSpect, which does compile with gcc  
4.+.

Peter and I are talking about ways to help ensure confusion is  
avoided between this 'new release of iNSpect'  (from Peter and Fatih)  
and the original version of iNSpect (from Toilers).

Peter/Fatih: thanks for improving the code structure of a very  
popular visualization tool.

Subject: [ns] How to accede to a membre variable in AODV from another file
	mac_802.11.cc?
Message-ID: <BAY104-F19016AD2DAFA2C93C22BC0EA0F0@phx.gbl>

Hello.

I?m trying to modify the routing protocol AODV. For this cause, I add a 
member variable ?energy? in the AODV class (aodv.h ) and modify it in 
aodv.cc file.
I want to recover this member variable of the class AODV which represents 
this value of energy "energy"  and to use it in  MAC_802-11.cc file and to 
decrease it in the method recvDATA but I had a bug :"Segmentation fault" at 
the execution of the programme!!. (I want to reach the same variable 
?energy? and to modify the same value in memory).
Veiled how I recovered this variable:
In  file mac_802-11.h I added:
#include "aodv/aodv.h"
............
class Mac802_11 : public Mac {
...........
friend class aodv;
public:
................
AODV *thisaodv;
...............
}

In file mac_802-11.cc I added:
void Mac802_11::recvDATA(Packet *p)
{
.............
                thisaodv->energy=thisaodv->energy-1;
..............
}

Where is the problem please. If it is possible, can you propose me other 
solutions.

Thank you in advance

Hello!

Seems to me that at the time when you try to access thisaodv->energy, 
thisaodv is null. Trying to dereference a null pointer would give you a 
Segfault for sure.

Have you tried to test whether thisaodv is null before doing

thisaodv->energy=thisaodv->energy-1;

?

Is thisaodv ever set correctly?


Good luck,

Martina
