  Hello
   
  I m working with a network scenario ....where link BW is 1.5Mbps and is
shared by both TCP and UDP flows. I used FTP over TCP and UDP based CBR
background load with the same packet size 512 bytes. ..................
   
  Simulation Time: is 30sec. I have to maintain CBR rate to 
   
  At   0-5  sec :   1Mbps
  At 5-10  sec:    1.5 Mbps
  At 10-15 sec:  .8Mbps
  At 15-20 sec:  .1.3Mbps
  At 20-25 sec:  1.5Mbps
  At 20-25 sec:  .4Mbps
   
  But i dont know how to control cbr rate in TCL script. My outputs are
always close to link BW .....they are not close to available BW.
   
  Here is my TCL Script : 
   
  set ns [new Simulator]
  #Open the Trace files
set file1 [open out.txt w]
set f0 [open output1.txt w]
   
  $ns trace-all $file1
  #Open the nam trace file

  #Define a 'finish' procedure
proc finish {} {
      global f0 ns nf
        $ns flush-trace
 #Close the trace file
        close $nf
 #Execute nam on the trace file
        exec nam out.nam &
 close $f0
          exit 0
}

Dear ns-users,

I have a simulation scenario setup with two wireless networks -- one network
is running the DSR protocol and the other is running AODV in promiscuous
mode. Is there a way to adjust the settings in ns2 so that the AODV nodes
can transmit farther and faster than the DSR nodes? And which settings get
adjusted? Essentially there will be two settings: one for DSR and one for
AODV nodes.




Thank you.

*Dear all,

I have a problem compiling the aodv.cc code and hope you can help me out to
solve the problem.

I try to compile the aodv.cc on ns-2.31 but it produces the following error:
*

*My question is, why can't the program find all the *.h files when the
location of the files is already correctly pointed. *
*
Does this problem has anything to do with environment path setting? Or do i
need to do something to incorporate the gcc compiler with ns2 using
Makefile?

This problem has dragged my work since i face the same problem when i run my
own program that need to include the necessary header files (aodv.h,
aodv_packet.h, agent.h & gridkeeper.h).
I've already point the header files to their exact locations but the same
problems still occur involving
other linking files such as cmu-trace.
** The following is my own program that produce the same error when i
compile aodv.cc. *

[root at fsksm friend_code2]# g++ countfriend.cc -o countfriend

Subject: [ns] ns-2 FAQ
Message-ID: <200802011648.m11GmkrL001668@ns-regression.ee.washington.edu>

            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
       already be answered there.

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

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

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

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

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

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

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

       A reminder about mailing list etiquette:
          + Please check the web pages and list archives before posting
            your question.
          + Please keep the body of your post to simple ASCII, not HTML.
          + Please do _not_ send large attachments (if what you have is
            bigger than a few kilobytes, put it on a web page and send a

Hi Theresa,

There exists an interesting patch which prevents
stations from routing packets towards intermediate
nodes (single-hop).

The patch is NOAH (NO Ad-Hoc) and you can find it here:

Hey, I had a similar problem few days back and I think its probably the same dependency problem. I think all you need to do is to install your all the components of  "Development " from your linux CD and make sure. I suggest you install all the Development Stuff: which are Development Tools, Kernel Development, X Software, GNOME Software Development and KDE Software. In simple words just insert the linux installation CD, choose to upgrade and install the ALL the stuff under Development. Make sure you install all the subcomponents( i.e. check all the boxes). Once linux is upgraded, I think it will install. It doesn't matter whether your using Red Hat or Fedora, the process applies to all.

NS uses a lot of development tools while compiling, thus the problem occur. Hope it works!

Good luck!

Maruf

Message-ID: <643556.59852.qm@web54104.mail.re2.yahoo.com>

Hi All,

I am currently working on developing a new routing protocol for Mobile Ad hoc Networks, the protocol uses the location information of each node in the network minimize the number of packet retransmissions. I am considering Network Simulator 2 for simulating the performance of the protocol. I started reading the NS-2 manual, but until now I am not sure whether I can set the get the location of each node during the simulation and use the location information to decide if a node after receiving a packet will retransmit it or drop it when it knows that all its 1-hop neighbors. Do I need to write some C++ code?. If any body can help me with this issue please reply.

Sincerely,

Abdulla

Debian - if you use Debian, you can install the whole emulation 
extension using apt-get / aptitude. Furthermore, NSE has been developed 
and tested on Debian for a long time.

Hi,

you need to install the kernel headers (or the complete kernel sources)
to compile this emulation extension.

Below is our first Call For Papers for WNS2 2008, the only
peer-reviewed event focusing on papers about ns2 (and 3).

Thanks to George Riley for offering to give the tutorial on the first day.

I should also note that the Internet Measurement Workshop is also
taking place earlier that week, nearby in a suburb of Athens.
http://www.imconf.net/imc-2008/cfp.html

The Workshop on ns-2 (WNS2) (http://www.wns2.org/) is a two-day
event held in conjunction with VALUETOOLS 2008, the Third International
Conference on Performance Evaluation Methodologies and Tools
(http://www.valuetools.org/), during the week of 20-24 October 2008
in Athens, Greece. WNS2 2008 follows the success of the first WNS2
workshop in 2006. A tutorial day on Thursday 23 October is followed
by presentation of reviewed papers on Friday 24 October 2008.

The main goals of this second WNS2 workshop are to bring together
networking researchers from both academia and industry, to discuss
recent advances, to identify future directions in network simulation,
and to foster interdisciplinary collaborative research in this area.
The workshop aims to emphasise the future evolution of ns-2, now that
ns-3 is under active development, and its extension in novel research
areas and networking technologies and scenarios.

TOPICS OF INTEREST
This workshop focuses on the ns simulator in itself, and in improving
simulation. We seek original contributions that go beyond the use of ns-2
“as is” for networking scenarios, and which try to make ns do something
new and different. Topics of interest for the Workshop include, but are not
limited to:

Structural developments/enhancements to the ns-2 simulator itself:
- Presentation/evaluation of new features/architectures under development
   for ns-3.
- Dynamic management of libraries / ns-Modules.
- Large-scale network simulation and model-based simulation approaches.
- Development of parallel and distributed versions of ns. Use of virtualization
   with ns.
- Integration of simulation and emulation.
- Post-processing tools, including GUIs for statistical analysis and visualization
   of simulation results.

Simulator use and validation of simulation accuracy:
- Validation of ns behaviour with experimentation and real data from
   implementations.
- Comparative studies of ns and other network simulation tools,
   both commercial and freely available.
- Environments and methodologies: the best practices, third-party code,
   helper scripts, and frameworks that serious users of ns recommend to get
   things done.

New simulation models and features:
- Wireless channel modelling.
- Frameworks for cross-layer support.
- Mobile and wireless networks, 3G/4G networks, WLANs, WPANs, WiMAX,
   Mesh networks...
- Delay-tolerant networking.
- Congestion-control and transport-layer issues in long-fat networks.
- Mobility: network mobility (NEMO), physical node mobility
   (e.g., group mobility models).
- Sensor and actuator networks (wireless, underwater, underground).
- Peer-to-peer systems.
- Network coding: data dissemination, encoding/decoding suites.
- Grid computing.

IMPORTANT DATES
Submission of research papers due: May 25, 2008
Notification of paper acceptance: July 1, 2008
Submission of camera-ready papers due: August 1, 2008
Paper presentation date: October 24, 2008

PAPER SUBMISSION
Papers should contain original material and not be previously published
or currently submitted for consideration elsewhere. Manuscripts must be
submitted by using the Cocus conference management system (http://www.cocus.eu).

Hi all,
Lloyd earlier posted the WNS2 conference call for participation, and that WNS2 will include an ns-3 tutorial.  I'd like to also announce that there are two ns-3 tutorials associated with upcoming conferences:

I will present an ns-3 tutorial at the Simutools conference, March 5, 2008, Marseille, France:
http://www.simutools.org/ns3.shtml

George Riley will conduct an ns-3 tutorial at the SpringSim conference on April 15, 2008, in Ottawa, CA
http://www.scs.org/confernc/springsim/springsim08/springsim08.htm

We'll put the materials on-line as they become available.

Dear All,

Greetings. I am a newbie in NS2 trying to achieve a  handover scenario
for a Vehicular movement ( a mix of Wired and wireless scenario) .

I have a trace of Mobile node's co-ordinates taken every 3.5 seconds.
Is it possible to simulate the movement of mobile node based on this
data instead of having to hard code it ?

I would appreciate any help in this regard.

Thanks and Regards

Subject: [ns] DSR algorithm
Message-ID: <721051.31987.qm@web63109.mail.re1.yahoo.com>

hi all..

In DSR routing protocol, there are 2 phase, which is route discovery and route maintenance. 

Roughly, if a source want to start communicate, it will check a route cache to determine whether the route already exist or not. If the route expired or don't exist, then they will initiate a route discovery process by broadcasting a RREQ. Then the neighbors will forward the RREQ to another node untill it reach the destination. The destination then response with RREP and send back to the source. Once the source received RREP, the communication will start. The algorithm also involves updating routing table, set timer,accumulating the address of each node between source and destination, rejecting a loop route and etc.  

I try to explore ../ns2.30/dsr/ but I didn't find the file that described/written this algorithm.

1. How the example in ../tcl/ex/wireless.tcl is link with ../ns2.30/dsr/ ? 
2. In which line wireless.tcl called the procedure or agent in dsr directory?

Message-ID: <d7fe4c5b0802060852ic018f53ic7eb103831e53cb2@mail.gmail.com>

Hi all,

I am trying to drop packets in a wireless situation. I have written code in
the mac-802_11.cc file to do such dropping. Even though the logic works, and
output (to the console) shows I should be dropping, the packet somehow still
gets sent to the link layer and gets processed (it shows up in the trace
file as the node receiving the ACK)


Can anybody help me resolve the issue? I want to actually drop the packet
for good to force a resend of the data packet.

Thanks!


Here I am trying to drop ACKs to force the source to resend packets....

Hi

project.
      The title is "A New Inter-domain routing architecture".For that I need
to use ns2 simulator.
      I have installed ns2 simulator in windows XP successfully.Then i saw
some simple tcl script programs from your presentation as well as from the
internet.
      Is it possible to define protocol in front end ie., TCL script itself.
      As for as backend is concerned we have to use C++ coding.
      If we define routing protocol in C++ then how can we connect C++ and
TCL .
      Then what is use for OTCL.
      Is it possible for simulating this kind of project which use routing
protocol..
      Give some examples which uses both C++ as well as TCL.
      Please help us..

Subject: [ns]  Problem of ARF Simulation
Message-ID: <15222177.post@talk.nabble.com>


Hello, everyone.

I encounter a problem when I simulate the ARF algorithm in NS2 with
dei80211mr patch.

I have installed ns-allinone-2.31 and dei80211mr patch upon ubuntu 7.10, and
excuted adhoc_tcp.tcl and infrastruct_rate_adaptation.tcl successfully. But
when I try to implement ARF in adhoc_tcp.tcl, there are seg faults in some
scenarios.

I add following codes to adhoc_tcp.tclto implement ARF:

    set ra($i) [new RateAdapter/ARF]
    $ra($i) attach2mac $mac($i)
    $ra($i) use80211g
    $ra($i) setmodeatindex 0

These codes are added in the block of agents configuring for all nodes in
adhoc_tcp.tcl. When  I set numUserPairs to 4 or 7, there are seg faults and
the trace file is empty. When I set numUserPairs to 5 or 6, the simulation
can be executed successfully. I also try to set numUserPairs and XMAX to
other values, but seg faults always appear in some scenarios.

I hope I can simulate ARF in WLANs when the number of nodes in WLAN is from
1 to 40 or 50 for every scenarios. But I encounter the above problem, and
didn't find the solution in the mailing list. Could you tell me how to find
the answers or what's wrong with my simulation? Thank you very much!

Sincerely,

Chunpeng

Subject: [ns]  time of RREQ and RREP
Message-ID: <15329850.post@talk.nabble.com>


 Roughly, In AODV routing protocol,if a source want to start communicate, it
will check a route cache to determine whether the route already exist or
not. If the route expired or don't exist, then they will initiate a route
discovery process by broadcasting a RREQ. Then the neighbors will forward
the RREQ to another node untill it reach the destination. The destination
then response with RREP and send back to the source. Once the source
received RREP, the communication will start. The algorithm also involves
updating routing table, set timer,accumulating the address of each node
between source and destination, rejecting a loop route and etc.
How can we know the route request time and route reply time?
Can we know the number of neighbors in this protocol?

Hi All,
I have been getting some emails about integrating NS2 , EURANE and Evalvid
(for simulating video streaming over UMTS networks), so I decided to write a
small document and I hope it will be of help. You will also find the sample
TCL script. I strongly recommend reading about EURANE and Evalvid and trying
each one separatly to gain knowledge and make sure they are working by
themselves before joing them together.
You can still send me an email if you need further help but PLEASE make sure
you go over this tutorial and do readings first.
Good luck to all of  you,

How to integrate NS2, EURANE and Evalvid, by Imad Abdeljaouad ( abdeljaouad
at gmail dot com )

After installing ns2 (ns2.30) and applying the EURANE patch, proceed with
the following:

Follow the steps in:
http://140.116.72.80/~smallko/ns2/myevalvid2.htm<http://140.116.72.80/%7Esmallko/ns2/myevalvid2.htm>

(The most important step is to include the 'mympeg' directory and recompile
ns2).

After that you can test with the script on the same page to see if evalvid
is working for wired links.

Next open the file mytraffictrace2.cc and comment the following:



if(f_==1){

                        agent_->set_prio(10);

            }else if(f_==2){

                        agent_->set_prio(11);

            }else if(f_==3){

                        agent_->set_prio(12);

            }else {

                        agent_->set_prio(f_);

            }



Then re-compile ns2 and make your TCL file and run it. It should work now.

Commenting these lines change the priority of each packet based on the frame
type it is carrying: I --> priority 1 , P --> 2, B --> 3 but there is a
priority field for each flow in EURANE, so doing this messes up the
priority/flow buffers of EURANE. So you have to assume that packets of same
flow have the same priority.



After creating the video file using the different tools as described in the
previous link, you have to follow steps in that tutorial in order to make
the sender trace. Before that, make sure you open the sender trace and
change entries labeled 'H' by 'I' (You can do that by editing the file and
replacing the letter H by the letter I). Then you can start your simulation
and move to the evaluation process and calculate the different QoS
parameters as well as reconstruct the received video.



I recommend that you use Evalvid on wired links first and make sure it
works. Then use EURANE with some traffic like CBR and make sure it works.
After that, you can try using both of them along.



If the simulation runs successfully but the receiver trace is empty, then
this is a bug in EURANE where packets are not delivered to the destination
application when using UM or UM-hs RLC modes, Follow instructions in this
thread: http://mailman.isi.edu/pipermail/ns-users/2005-May/049765.html to
solve the problem.

ffmpeg is an open source tool for converting football.divx to
football.m4v(MPEG4):

./ffmpeg -s qcif -vcodec mpeg4 -r 30 -b 64 -g 30 -bf 2 -i football.divx
football.m4v



MP4BOX is for hinting the video track:

./MP4Box -hint -mtu 1024 -fps 30 -add football.m4v football.mp4



Mp4trace is for creating the sender trace  (st_a00):

./mp4trace -f -s 192.168.0.2 12346 football.mp4 > st_a00

(the program mp4trace marks 'I' frames as 'H' instead of 'I', just open the
output file st_a00 and replace 'H' by 'I' so as to have good results after
the simulation)



Run the TCL Script:

ns mympeg.tcl



Change missing frames by 0:

./etmp4 -p -0 sd_a00 rd_a00 st_a00 football.mp4 a00e

./etmp4 -p -0 sd_a01 rd_a01 st_a01 football.mp4 a01e

./etmp4 -p -0 sd_a02 rd_a02 st_a02 football.mp4 a02e

./etmp4 -p -0 sd_a03 rd_a03 st_a03 football.mp4 a03e



Change missing frames by trancating: ( if -f does not work, try -p)

./etmp4 -p -x sd_a00 rd_a00 st_a00 football.mp4 a00ex

./etmp4 -p -x sd_a01 rd_a01 st_a01 football.mp4 a01ex

./etmp4 -p -x sd_a02 rd_a02 st_a02 football.mp4 a02ex

./etmp4 -p -x sd_a03 rd_a03 st_a03 football.mp4 a03ex



Calculate PSNR:

./psnr 176 144 420 football.mp4 a00e.mp4 > psnr_output0

./psnr 176 144 420 football.mp4 a01e.mp4 > psnr_output1

./psnr 176 144 420 football.mp4 a02e.mp4 > psnr_output2

./psnr 176 144 420 football.mp4 a03e.mp4 > psnr_output3



Those tools are available on the useful link above.

I hope that it is possible somehow to incorporate all of them in one ns simulator.

Hi,

I have also working with the UTRAN/UMTS extension and EURANE as well. My focus is to develop a complete UMTS Release 6 (HSDPA) extension for ns-2.32. And thus I have started from the scratch. If you can send me the patch/the necessary files it will be very much helpful.

I have already printed out both the UTRAN/UMTS docs and EURANE two pdf manuals for studying. So, it will be very much helpful if can guide me someway.

Thanks in advance.

Dear Fauzan,
I don't know about this but did you try adding a normal BS node like this:

$ns node-config -UmtsNodeType bs \
            -downlinkBW 32kbs \
            -downlinkTTI 10ms \
            -uplinkBW 32kbs \
            -uplinkTTI 10ms \
            -hs_downlinkTTI 2ms \
            -hs_downlinkBW 64kbs \

set bs1 [$ns create-Umtsnode]

$ns node-config -UmtsNodeType bs \
            -downlinkBW 32kbs \
            -downlinkTTI 10ms \
            -uplinkBW 32kbs \
            -uplinkTTI 10ms \
            -hs_downlinkTTI 2ms \
            -hs_downlinkBW 64kbs \

set bs2 [$ns create-Umtsnode]


But before, check the eurane user guide for that possibility. I know that
there is support for single cell environment only but I don't know about how
many BSs you can put !
Good luck,

Hi all,
Is there a way to obtain the source to (different) destination paths of a
multicast tree in the MAODV protocol say using breadth first search or
Dijkstra's? But first, I need to know where to look to start traversing from
source node.

Is there a way I can do this with the Multicast Routing Table in MAODV? If
so, how do I access it? Or do I need to do this from the trace file itself?
If someone even has done this in an unicast AODV setup, please let me know
how.

Thanks,

Loading connection pattern?

Starting Simulation?

channel.cc:sendUp - Calc highestAntennaZ_ and distCST_

highestAntennaZ_ = 1.5,  distCST_ = 89.8

SORTING LISTS ?DONE!

NS EXITING?

1.....  Why is this happening?




I guess the problem is with the inclusion of Phy/WirelessPhy channel. Where is it located in the ns2.27 folder? How do I verify if it is present?  N How do I include it?


When I execute validate, I get ?the outputs deviate from standard
results?. Can you tell me where the problem lies?  




2.  Also once the GCC 4.1.x: ns-2.27-gcc410.patch  patch is applied, nrlsensorsim extension for ns 2.27 is showing problems on installation. I had to omit that. 

3. Do I have to install 802.15.4 layer support separately to simulate sensor networks? How do I do it?


Kindly help. It
is extremely important to me.

Hello everyone,
 
Does anyone know how to model multiple wireless "channels" in a given
wireless network?
 
I am trying to model a node which can dynamically change frequency (i.e.
channel) if its current channel gets blocked or congested.
 
Thanks.

Subject: [ns] Need OBS simulator
Message-ID: <1202907596.4024.6.camel@localhost.localdomain>

Hi,  
  
I am trying to create a simulation of a network that uses TCP over OBS
using ns-2.  
The problem is that I can't download the OBS simulators that I found
which are: 

1. OIRC OBS-ns Simulator from http://wine.icu.ac.kr/~obsns/ 
2. OBS-ns simulator from University of Maryland DAWN research lab
(http://dawn.cs.umbc.edu/owns/) 

I can't download the first one because when I fill the form with my
email and other information, I receive an email with a link to a page
that says that this page is expired. 
The second one it's because when I try to follow the link
http://dawn.cs.umbc.edu/owns/ says that I don't have access to that
directory.  

Thanks for your time

HI,
I am using NS 2.31 on FC-6.
Whenver I run a TORA routing protocol , I get a message like given below.
But all other protocols like AODV, DSR and  DSDV run smoothly.
So does any 1 have any clues??
The error is:

Subject: [ns] ERROR: Undefined symbol when making ns2 after code patch
Message-ID: <1202926169.47b33259aeb94@webmail.vt.edu>

All,

Hello. I have an AIX box on which I am running ns2. I applied the patch for NOAH
(http://icapeople.epfl.ch/widmer/uwb/ns-2/noah/), and then tried running
"./configure", "make clean" and "make" in the directory "ns-2.31", but am
getting errors saying that I have undefined symbols. Has anyone run into this
before? Any suggestions on how to fix this? Any help would be much appreciated.

Here is my output for "make":

Hi,

I have a network topology generated by GT-ITM and I need to add a link
failure probability before I run the simulations.

For example how to run network simulations with link failure probability 0.2?

Any hints?

cheers!

highestAntennaZ_ = 1.5,  distCST_ = 89.8

SORTING LISTS ?DONE!

NS EXITING?

1.....  Why is this happening?




I guess the problem is with the inclusion of Phy/WirelessPhy channel. Where is it located in the ns2.27 folder? How do I verify if it is present?  N How do I include it?


When I execute validate, I get the outputs do not match standard results. Can you tell me where the problem lies?  




2.  Also once the GCC 4.1.x: ns-2.27-gcc410.patch  patch is applied, nrlsensorsim extension for ns 2.27 is showing problems on installation. I had to omit that. 

3. Do I have to install 802.15.4 layer support separately to simulate sensor networks? How do I do it?


Kindly help. It
is extremely important to me.

I did it in ns-2.30 but some modifications are needed in the code. I see if
I can upload it on my web site with some instructions and simulation sripts.

Hello everyone,
 
 
in ns2 there is a file called "aodv.cc", in this file there is a function called "recv()" .
I want to know which part of this function that responsible for "when any destination receives a data packet".
 
 
 
 
thanks
 
safaa saad-eldeen,

Message-ID: <443d884d2d5e532f.2d5e532f443d884d@mailsrv.unirc.it>

Hello,

I would like to understand when in a wireless simulation the first field
of the trace file could be set to "f".  
I'm using AODV as routing protocol and I think that the multi-hop packet
forwarding is enabled by default. Is this right?
Thanks a lot!

Have a nice sunday!

Hi,
I'm using NS 2.31, i need to make communication between two disconnected
wireless networks with the help of a ferry node.
The ferry is the moving node that go in the range of the disconnected
networks from time to time.
The ferry must act in a Strore-Carry-Deliver method.
For that, i need the ferry to have a buffer to store the packet sent from
one node and deliver to the destination node which is out of range for the
first node.
I'm using AODV protocol.

Should i modify the AODV protocol for this..? or is there any way without
modifying the protocol to work with the application layer itself.

I attached the snapshot in which i created the ferry without that protocol..
In that snapshot nodes 0,1,2,3 are stationary wireless nodes, where node 4
is the ferry which moves to others range.

 Help me in this..

Hi all,
I am using the random motion of the nodes in my wireless scenario. In the below line, which is not random, we can adjust the speed of the moving nodes.
 
$ns at $time $node setdest <x2> <y2> <speed>
 
My question is that how i can change only the speed of the moving node in tcl, although the nodes still moving random fashion.
 
Thanks in advance.

I am trying to simulate a 3D simulation. ns2 has all mobile nodes and access
points depicted graphically via the use of x,y, and z coordinates, however I am
not sure how to simulate these correctly. I used the FreeSpace radio-propagation
model, which doesn't complain if you give your nodes a non-zero z coordinate,
but then I got unexpected results and again looked through my code.

I then realized that every simulation example I had seen has "$topo
load_flatgrid $opt(x) $opt(y)". Is there a way to load a 3D grid, rather than a
2D grid? If so, how is that done?

Thanks in advance.

I'm trying to simulate the DSR protocol on NS-2.28. While running the simulation with the ENERGY PARAMETERS set i'm constantly getting a Segmentation Fault. If I remove the energy parameters then the script runs fine. Also, if I change the protocol to AODV or DSDV the script runs fine. 

Can anyone please advice me on the issue. I've attached the script file.

Regards

Siddharth

Hi guys,

I am new to ns2..But am wrkin on well from the kind of tutorials u all have
created....
I have a problem ....How should I create more than one link between the same
nodes...

It is not the different agents that are to be connected ...I want to have
two different physical links..
Can I do that????

To: ns-users at isi.edu


Hello Friends,
Actually i am facing some problems while simulating wrls-dsr.tcl.
I arranged the nodes in a straight line aligned along the X axis with the
distance between the 2 nodes 100. So i arranged 8 nodes.
The coordinate of the 1st node is (5,5) , 2nd node (105,5) and of the 8th
node (705,5).When i tried to simulate this i got an error(segmentation
fault).

When i arranged 6 nodes with the coordinate of the 6th node as (555,5) i cud
simulate it without any problem . When I increased the value of x to 556 ,
it once again gave an error . I am not sure about this , can someone please
help me out.

Hi. I was trying to use the shadowing radio propagation model, but am getting a
floating point exception. I got this both when running on a windows box
(cygwin) and on an AIX box. gdb said "Program received signal SIGFPE,
Arithmetic exception", and when I use the same code with FreeSpace or TwoRay I
have no problem. Has anyone else had this issue? How do you fix it? I'm
attaching some code; if more code is necessary to look at, please let me know
and I'll add the whole file. Thanks in advance.

Subject: [ns] problem - simulate a behaviour of some network
Message-ID: <47BDA91F.7060304@interia.pl>

Hi,

I am a new ns user (version 2.29 under Windows - cygwin). I have to 
simulate a behaviour of some network with 22 nodes, so I would like to 
connect them together: I mean that the packets will be send from node 0 
to all nodes in the network, from node 1 to all nodes in the 
network....etc. On the bottom of this mail you can see my script 
simulating this network. It's working, but the results are wrong. The 
simulation last from 0.1 to 5.0 seconds, but after a few decimals of 
second the packets are only sending from node 20 to node 21 and 
inversly. Could somebody have a look at my script and say what I'm doing 
wrong?

Subject: [ns] can't install otcl-1.13 on Mac OS X 10.5.2?
Message-ID: <200802212355.m1LNtri14999@cisco.com>

I'm trying to install octcl 1.1.3 on Mac OS X 10.5.2, as part of the ns 2.32 allinone install:

checking for X11 header files
checking for X11 library archive
checking for XOpenDisplay in -lX11... no
can't find X library

Now, I've installed XCode 3.0. I've installed the development headers found in separate packages on the Leopard install disk (so e.g. I've got the OpenGL stuff - though I've got another program that swears blind they're Not There.). I gave up on MacPorts and managed to install Fink. I've even installed Quartz for the missing bits of X that Apple didn't ship. And otcl still won't configure.

Any hints?

thanks,

L.

Subject: [ns] Reserved flow has longer delay than BestEffort flow on
	RSVP/ns???
Message-ID: <200802221731372963161@gmail.com>

Hi All,

I've installed RSVP/ns and it runs well with examples in RSVP/ns document by Marc Greis..
I've ran ns~\tcl\ex\rsvp\rsvp_distinct.tcl successfully, and got the same data as Figure 5( Measurements for distinct reservations) in RSVP/ns document.

Then,I added trace-ralated codes in rsvp_distinct.tcl, to get delay,jitter,and loss for each flow. I found when a flow is successfully reserved,its loss become much lower than other BestEffort flows,so the receiver(node0) get more bits from reserved flow.But its delay,jitter become much higher than other BestEffort flows. e.g.When node0 have reserved 1k for node2 during 300s~900s, I get the following statistics:
 
SrcNode DstNode      delay(s)      jitter(s^2)     loss
2             0            1.350703      2.333099        0.326804
3             0            1.046185      0.000005        0.403614
4             0            1.046090      0.000004        0.392826

I've check my awk statistics script,there's no problem in it.And I've tried other periods(900s~1200s,1200s~1500s,etc.),all statistics are similar to above.

In my opinion,RSVP is expected to provide lower delay and jitter(or an upperbound) than other BestEffort flows,though only Controlled Load Service is supported in RSVP/ns.Am I right?

How to explain this phenomena? Is higher delay and jitter a cost for lower packet loss?

I would appreciate your help.
Thanks very much~

Best wishes,
michael.

I'm using nam 1.11 under Windows XP / Cygwin 1.5.25. In my application,
I need to create nodes and links dynamically, i.e. after the
initialization phase. This feature was introduced in nam 1.6. Creating
nodes and links dynamically does work, but it is not possible to
visualize the transmission of packets over the newly created links ("h"
and "r" trace event codes) - the packets just won't appear in the
window. Has anyone come across this problem before and knows how to
solve it?

Many thanks,

Konu: how to change the speed of node while randomly moving


Hi all,
I am using the random motion of the nodes in my wireless scenario. In the below line, which is not random, we can adjust the speed of the moving nodes.
 
$ns at $time $node setdest <x2> <y2> <speed>
 
My question is that how i can change only the speed of the moving node in tcl, although the nodes still moving random fashion.
 
Thanks in advance.

Asunto: [ns] binding variables

Hello all,

I have develop a new app layer over udp. I know how to bind INPUT VARIABLES, 
but I don't know how to do to return values to read the in my tcl simularion file.

I have written the next code:

// Constructor (also initialize instances of timers)
VDTPapp::VDTPapp() : running_(0), snd_timer_(this), ack_timer_(this)
{
  bind("chunk_size_", &chunk_size_);
  bind("file_size_", &file_size_);
  bind("pktsize_", &pktsize_);
}

chunk_size_, file_size_, and pktsize_  are input variable, can someone tell me how
can I bind OUTPUT variables.

Thank you...

Subject: [ns]  DSR routing protocol problem
Message-ID: <467465.23944.qm@web27602.mail.ukl.yahoo.com>

Hello All,

I have a problem when I try to simulate a wireless network, just
when I use DSR routing protocol. When I use others I have not 
any problem.
The problem is that during the simulation there is an EXCEPTION 
with the next message:

7 [main] ns 1880 _cygtls::handle_exceptions: Exception: STATUS_ACCES_VIOLATION 
1833 [main] ns 1880 _open_stackdumpfile: Dumping stack trace to ns.exe.stackdump

can someone tell me why?

Best regards... Jamal

Subject: [ns] About wireless cards specifications simulation
Message-ID: <946565.30158.qm@web44904.mail.sp1.yahoo.com>

Dear all,
   
  I have to simulate an infrastructured  wireless network behavior using different wireless cards specifications. I want to test the network performance using 802.11a cards with high transmit power level (not less than 600 mW). I have choosen the XtremeRange5 card but what I have realized is that its outdoor range is over 50 km and it indoor range is 150 m, during simulation if two nodes are further than 150 m the link throughput is 0, so is it realistic to assume that I deal with indoor networks? what I mean I am dealing with similar networks topology to wireless mesh networks, can I assume this network to be indoor and apply this NIC card specifications?
   
  Waiting your replies.

Basically there is no difference if you increase the transmission power 
or use a high gain antenna. So, apart from the transmission power, the 
sensitivity of the transceiver is what makes the most important 
difference between two wireless cards.

Before you proceed with your work you should read something about 
wireless propagation. Just as an example, an outdoor range of 50km is 
only possible if the transmitter is placed high enough above ground. 
Otherwise you will not have a free line of sight and fresnel zone. When 
I remember right, for 50km distance the transmitter needs to be placed 
about 80m above ground. The environment defines how the transmitted 
signal is attenuated. Just imaging you are inside a metal elevator - 
then you probably get an "indoor range" of 1m.

To answer your question: NO, it is absolutely not realistic to deduce 
from a result of 150m transmission range to be in an indoor scenario.

I suggest that you start  by selecting a propagation model that mimics 
the effects experienced in an indoor environment (e.g. multipath 
propagation, shadowing, interference ...). If you have such a 
propagation model, you can start to investigate effects caused by the 
transmission power, cars specification, protocol ... whatever you like.

Hope that gets you started,
Daniel.

Thanks to gier egeland and David Viera for the hints.

./configure --x-includes=/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/include --x-libraries=/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib
make

worked for me to successfully configure and make otcl-1.13, tclcl-1.19, and ns-2.32 on Leopard.

That also worked for configuring nam-1.13, but that failed at the linker stage bleating
Undefined symbols:
  "__TkCreateXEventSource", referenced from:
    _TkpInit in tkUnixInit.o
so I grabbed nam-1-20080222.tar, which failed with the same linker error.

(I was using the available Tcl/Tk in the system, but using the allinone compiled Tcl/Tk made no difference here.)

I expect that the above will work for any Mac OS X 10.4 or 10.5 with XCode with the added X11 headers -there's a pkg on Leopard Install disc 1. The parallel MacOSX10.5.sdk/ tree is pretty empty, relying heavily on the base code in 10.4u (for universal: on Intel and PowerPC). On 10.3, using directories under /Developer/MacOSX10.3.9.sdk/  *may* well work - that directory exists, but the tree under it is mostly empty under Leopard. Since 10.3 changed so much during its lifetime, probably easiest to forget about 10.3 support altogether.

I think that these locations need to be special-cased for Darwin in the all-in-one installer, just as Cygwin is.

My, validate complains about 'no class variable LanRouter::debug_' a lot...

I've installed the development headers found in separate packages on the Leopard install disk (so e.g. I've got the OpenGL stuff - though I've got another program that swears blind they're Not There.). I gave up on MacPorts and managed to install Fink. I've even installed Quartz for the missing bits of X that Apple didn't ship. And otcl still won't configure.

Hi,
   
  First of all thanks alot for your fast response.
   
  You have said that :
  "To answer your question: NO, it is absolutely not realistic to deduce 
from a result of 150m transmission range to be in an indoor scenario."
   
  Do you mean that I cannot assume an indoor range to be 150m, or I cannot assume that an infrastructured network is working in an indoor environment?
   
  The point that I want to get to, is that in the standard it is specified that the maximum transmit power for 802.11a cards in the range 5.725-5.825 GHz can reach 800 mW, following this can I assume a range of 150m (for example) for a card using 600 mW as its transmit power, apart from the propagation model or lets say I am working with TwoRayGround model, can I assume this or one can argue that my simulation settings are not real?
   
  Thanks again and waiting your reply,
   
  gaby

Lloyd,

Thanks, I've added the above to the troubleshooting page:
http://nsnam.isi.edu/nsnam/index.php/Troubleshooting

I personally haven't had problems using allinone package with OS 10.4, 
Xcode 2.4 on a G4 PPC, so maybe something has changed with Leopard or 
the newer Xcode.

MW-Node to 2.30, it works, but it won't work for 2.31.

Is there a way to use these two together? If so, using which version, and what

What I tried so say is: "If your transmission range is 150m, you cannot 
assume to be in an indoor environment".
For your question:
a) you cannot assume that the transmission range will be 150m in an 
indoor environment. Usually, when someone gives a transmission range, he 
means that the transmission range can be _up to_ this value. You can 
never assume a minimum range (s. the elevator example).
b) An infrastructured network is known to work in an indoor environment.

>   
In a general environment (one you have no specific knowledge about) you 
cannot assume anything (s. the elevator). If you define some properties 
of the environment as prerequisits (e.g. "we are in an open park area 
with clear line-of-sight and no obstacles within the first fresnel 
zone") you can assume a transmission range with high confidence (e.g. 
150m +/- 20m). In an indoor environment this is quite difficult because 
the variation is extremly high - something linke 50m +/- 50m does not 
help you much. Furthermore, even in a static indoor environment (one 
where anything remains at its position, no people moving, no doors 
opened/closed etc.) the signal strength between a pair of stationary 
WLAN transmitters will not be constant. You will find more information 
and references to other peoples' work in my thesis 
(http://deposit.ddb.de/cgi-bin/dokserv?idn=980478588) or in the papers 
of my collegues that continued / extended my work 
(http://wwwivs.cs.uni-magdeburg.de/EuK/forschung/publikationen/index.shtml).

So my advise - start your work with a discussion of the properties of 
the environment, than that of your devices, and finally that of your 
protocol. From all this you can derive the performance of your 
communication / application with reasonable confidence. And don't forget 
- transmission power is a property of your devicey, but transmission 
range is not. It is a result of the combination of transmitter, 
receiver, environment, and signal encoding.

Subject: [ns] Can anybody explain why this happens?? network perfromance
	depends on used data structure
Message-ID: <881640.97784.qm@web51711.mail.re2.yahoo.com>

Hi all,
   
  I have modified AODV protocol to support other routing metric than hop-count, at the final stages of performance testing I have realized the following:
   
  I have added new fields to RREQ and RREP packets, lets say I have added three quantities of type double (x, y, z) to the RREQ to allow intermediate nodes to calculate the new  route metric. What I have realized that the protocol performance will be different for the following two cases:
  -- if I have added these values as an array to the RREQ header (i.e.double  new_metric[3]), 
  -- if I add them as a three elements (i.e. double x, double y, double z).
   
  Also if only one element of the array is filled (i.e. new_metric[0], for example) the performance will be different from having all array elements are filled.
   
  I am measuring the total network throughput, the results are different for different RREQ format elements arrangements.
   
  Can any body explain this to me? what is happening here?
   
  Thanks,
   
  Ghada

Hi Abdullah,

Assuming the node address is stored in 'index':
--
double x, y, z;
MobileNode *node_ = (MobileNode *) Node::get_node_by_address(index);
node_->getLoc(&x, &y, &z);
--
Now, x, y and z contain the current node position.

Hi,

I wrote a code to calculate many parameters: packet delivery ratio,
normalized throughput, routing overhead ratio, end2end delay, hop count and
connection time. Furthermore, this code is suitable in case you want to
repeat your simulation experiment many times to take the average of them.
This code is freely available and you can download it from the following
link between '(' and  ')':

(
http://www.ikt.uni-hannover.de/fileadmin/institut/mitarbeiter/bali/pl-sim-1.
1.zip )

There is a text file that explains how to use the code. However, I wrote
this code for my own use and for my specific scenario.

Best Regards,
Samer

Hi Basim,

Yes, you are right. The file "gen_pl.tcl" generates a file called
"run_pl_sim" in which 30X50 simulation runs (using the file "pl.tcl" and the
default values listed in the file "defaults-802.15.4a.tcl") will be listed,
i.e., there is 30 simulation experiments, and each experiment is repeated 50
times. 

Also the file "run_pl_sim" will contain some commands to extract 4 trace
files from the original trace file for each simulation run (using the files
frd1.txt, frd3.txt, frd8.txt, frs1.txt, frs3.txt, and frs8.txt). 

When the file "run_pl_sim" is executed , there will be 30X50X4 = 6000 trace
files.

(*) What should I do with these 6000 trace files?
In MATLAB, run the file "info_pl.m" with the same 5 parameters as in
"run_pl" file (see file 'instructions-before-using-codes.txt'). This will
extract the useful information from the trace files. The 6000 trace files
will be replaced by 30X50 files.
(NOTE: "run_pl" and "info_pl" can be executed simultaneously to save time)

(*) What should I do with the 1500 information files?
In MATLAB, run the file "analyse_pl.m" with the same 5 parameters as in
"run_pl" file. This will tabulate the results obtained from 1500 files into
one file only.

(*) What should I do with this one file?
In MATLAB, run the file "plot_pl_avg.m" to obtain various plots and graphs.

Hope this help.

Best wishes,
Samer

Hello Samer

its a nice effort.
after having an overview, I think u wrote your code in tcl. right?

would u kindly guide me, as also I want to run many simulations:

whats the high level view of your approach? what i mean is:

BIG PICTURE
loop:

initialize NS
create a scenario
run the simulation
get the results processed
terminate NS

end loop:

Also could you plz specify how are u getting the throughput stuff by
processing the out.tr files by something like perl...? How do u
average out the throughput for different runs, as I guess, you would
get different separate out.tr files?

thanks many.

Message-ID: <984610.4657.qm@web23205.mail.ird.yahoo.com>


Hello all,

I am trying to simulate mobile nodes with multiple interface and using
 different routing protocols for each interface. I have applied the
 MW-Node patch from here:
http://www.q2s.ntnu.no/~paquerea/ns.html
However, from the provided documentation I understood that the existing
 protocols don't work with this patch and they have to be adapted. I
 haven't made any changes in the C++ libraries until now and I am afraid I
 would do some fatal mistake. Does anyone have an example of a protocol
 adapted for MW-Node or at least some guidelines? Or does anyone knows
 a different patch that might provide multiple interface with different
 routing protocols?

Thank you,

Razvan.

Hi all,
   
  I have modified AODV protocol to support other routing metric than hop-count, at the final stages of performance testing I have realized the following:
   
  I have added new fields to RREQ and RREP packets, lets say I have added three quantities of type double (x, y, z) to the RREQ to allow intermediate nodes to calculate the new  route metric. What I have realized that the protocol performance will be different for the following two cases:
  -- if I have added these values as an array to the RREQ header (i.e.double  new_metric[3]), 
  -- if I add them as a three elements (i.e. double x, double y, double z).
   
  Also if only one element of the array is filled (i.e. new_metric[0], for example) the performance will be different from having all array elements are filled.
   
  I am measuring the total network throughput, the results are different for different RREQ format elements arrangements.

(15) rm /root/results/pl/regular/uwb/AODV/f1/uwb-AODV-1-11-1-temp2.tr

The first command run the simulation and it results in one trace file
"uwb-AODV-1-11-1.tr" (NOTE: I renamed my ns-2 simulator name, so I typed
"nsuwb" instead of "ns" because I used a version that support UWB networks).
Now to obtain information about throughput, routing overhead, ...etc, I
found it is better to filter the original trace file and replace it with 4
small files. This is done with commands (2) to (11). Then I deleted the
unwanted files from my system with commands (12) to (15).

Note: the first five parameters (regular uwb AODV 1 f) are specified in my
code in the file "run_pl". The 6th and 7th (11 1) parameters are added by "
gen_pl.tcl". The 6th parameter specifies the distance between nodes (in the
above example it is 11m), while the 7th parameter determines the seed of the
simulation. In my network scenario, I varied the distance between nodes from
1 to 30m with a step of 1. For each distance value I repeated the simulation
50 times.

So imagine this, to run 30X50 simulation, I should write 30X50X15 commands
which is of course unfeasible to do manually!!! So I chose to generate these
commands automatically using "gen_pl.tcl". These commands will be listed in
the file "run_pl_sim".

To sum up, the file "run_pl" will use the file "gen_pl.tcl" to generate a
file called "run_pl_sim" in which 30X50 simulation runs will be listed, in
addition to some commands to extract 4 trace files from the original trace
file for each simulation run. Then the file "run_pl_sim" will be executed.

Then, In MATLAB, run the file "info_pl" with the same 5 parameters as in
"run_pl" file. This will extract the useful information from the trace
files. Here, every 4 trace files that represents one simulation run is
replaced by one file with only one line (containing information such as
number of sent packets, dropped packets, received packet, connection time,
...etc). Therefore, the 6000 trace files will be replaced by 30X50 = 1500
files.

Then, In MATLAB also, run the file "analyse_pl" with the same 5 parameters
as in "run_pl" file. This will calculate throughput, routing overhead,
...etc, for each file of the 1500 files. the file "analyse_pl" will
generates two files, one file contains 30X50 = 1500 lines (no average is
provided), and the other file contains the average of every 50 simulation
corresponding to a certain distance between nodes, that is, the second file
contains 30 lines, each line contains the average throughput, average
routing overhead, ...etc.

As I said before, I wrote this code for my own use. I did not write enough
documentation so that other people can use it. But I hope that this email
gives some hints for those who want to understand this code. 

Also, I think one will get more hints when he understand the network
scenario simulated by this code. For more information about the network
scenario (node mobility, traffic, . etc.) see the following paper:
S. Bali, J. Steuer and K. Jobmann, "Performance of Three Routing Protocols

Subject: Re: [ns] repeat simulation

hello Samer

I dont think if I quite understand the role of run_pl_sim? is it
another tcl file or trace file generated by gen_pl.tcl? what is this
30x50 runs..i mean the values for different parameters to be used in a
specific run?

lets consider one example of throughput averging: so you have 50 trace
file for a particular setup of parameters; only you repeat the
simulation with different seed values, while keeping other parameter
values same. Which means probably you have 50 trace files. Now you
need to average out these 50 trace file into one..right? probably the
way you would do it is to geneate a throughput file for each of these
50 files, and then add the corresponding values of same time interval,
and then divide by 50?

thanks many.

Avishek,

I am not using DREAM/LAR at the moment and do not even have a working
ns2 at this time, so I can't give you step by step instructions... (My
research interest shifted...)

The questions you have are general questions related to the LAR/DREAM
code written by TOILERS. You should ask the email list
(ns-users at isi.edu) for general answers and after you figured out the
solution to your problems, please go ahead and update the ns2 WIKI
(http://nsnam.isi.edu/nsnam/index.php/Main_Page) so that other people
could find the solutions you found, too.

As to your particular question:
If I remember correctly, the box.tcl does not specify a mobilty file (as
stated by the error message). There are two solutions to this (again, if
I remember correctly): either do what the error message told you to to,
i.e. call

$ ns box.tcl MOBILITY.FILE

or simply include a mobility file inside box.tcl (for examples on how to
do this look at any more recent tcl input file for a wireless scenario...)

Please check the ns2 manual on how to create mobility files.


Again, please add any insight you gained into the ns2 wiki
(http://nsnam.isi.edu/nsnam/index.php/Main_Page) so that others can
learn about and from your work.

Hope that helps.

Claus

Welcome to posting to the ns-users mailing list!

We automatically send this message to every new person who sends mail
to the list.  You should only receive it once.  My apologies if the
program contacts you twice, perhaps because you have multiple e-mail
addresses or send mail from multiple machines.

If you are an experienced ns-user who simply has not posted since we
started using this responder, our apologies for inconveniencing you
with this message.  This message is intended to help inform users and
cut down on redundant posts, which benefits everyone.

Please look at the attached list of ns Frequently Asked Questions.
If it answers your question, great!  You're done.
If not, please RE-SEND your original message to ns-users at isi.edu.
A copy of your original message is included below for reference.

You will NOT have to do re-send your message every time you post, only
the FIRST time you send from a new account.  The goal is to quickly
help new users find the FAQ (hopefully answering their question).

Thanks,

           The Network Simulator ns-2: Frequently Asked Questions

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

    * _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.

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

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

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

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

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

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

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

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

Hi to everyone,
here http://wpage.unina.it/marcello.caleffi/ns2/aomdv.html you can  
find my personal 2-cents-AOMDV-code for the current release (2.32).
I've updated an older version of AOMDV code, by merging it with the  
current AODV code and adding some personal contributes. I don't  
remember who gave me the original code; if someone knows who are the  
autors, please let me know. This code, differently from the original  
one, add the AOMDV as a new protocol in the ns tree and each code  
line which "adds the M to AODV" is indicated. Clearly, there is no  
guarantee about this code, however I've used it in the last year for  
my research activities without any troubles.

Subject: [ns] Handover Latency in 802.21
Message-ID: <991704.13278.qm@web60222.mail.yahoo.com>


Hi all,

I am working on 802.21 protocol and accomplishing soft handover between 802.11 and 802.16 standards.

I am using the NIST patch of NS2 implementation for MIH(Media Independant Handover 802.21) protocol.

Anybody has an idea how to calculate the handover latency in thisscenario. I have a Multi interface mobile node connected with BS(Wimax)and AP(WLAN). Both BS and AP are connected to the CN(CorrespondantNode) via router. After a handover decision in the MIH of mobile node Isend a request to the CN to redirect the flows. How can I calculate thehandover latency ?


Thanks in advance.
Noman.

Message-ID: <24558076.8491204283772101.JavaMail.tomcat@pingus>


You first have to select the source routing mode

$ns src_rting 1

and then specify the route you want. For example if you want to 
send packets between a TCP Agent in node 0, and a sink in node 1, 
you can do it as follows:

#Create a TCP agent and attach it to node n0
set cbr0 [new Agent/TCP]
$ns attach-agent $n0 $cbr0
$cbr0 set fid_ 0

#Create a TCP agent and attach it to node n3
set cbr1 [new Agent/TCP]
$ns attach-agent $n3 $cbr1

$cbr1 set fid_ 1

$cbr0 target [$n0 set src_agent_]
$cbr1 target [$n3 set src_agent_]

set temp [$n0 set src_agent_]
$temp install_connection [$cbr0 set fid_] 0 1 0 2 4 3 1
set temp [$n3 set src_agent_]
$temp install_connection [$cbr1 set fid_] 3 4 3 2 4

set null0 [new Agent/TCPSink]
set null1 [new Agent/TCPSink]

$ns attach-agent $n1 $null0
$ns attach-agent $n4 $null1


$ns connect $cbr0 $null0
$ns connect $cbr1 $null1


Where the route between nodes 0 and 1 is [0 2 4 3 1]

Subject: [ns] large scale network simulation problems
Message-ID: <99a746170802290426x24faeeb2rf884fd17f9140cee@mail.gmail.com>

Hi,

I am using pdns -2.26 with the aim of simulating real-world large scale
networks. I have written tcl script which simulates a network consisting of
3 possible topologies - ring,tree and star with number of nodes input by
user. I am facing a problem in ring topology only. Suppose I create a ring
of say 100 nodes. Then packets get dropped as the default TTL value in class
Agent in tcl/lib/ns-default.tcl is 32 and the packet has to make more than
32 hops to reach its destination. When I increased the default TTL value to
a conveniently high value and compiled ns, and ran the program,  there were
no drops. However, I want to set default TTL value on run-time based on
topology created, instead of setting an unnecessarily high default TTL. Can
anyone please suggest how I can set default TTL for all nodes and is it
possible to set TTL for selective nodes only?

Also, I was seeing other network simulators like GTNets and even NS 3 have
provided support for following topologies : tree, star, dumbbell and
grid,etc. but not ring. Is ring topology not ideal for representing
real-world Internet traffic? Why are tree,star,dumbbell best for
representing large-scale Internet traffic??

Subject: Traffictrace format problems
To: ns-users at isi.edu


Here is my problem:

I am trying to create network traffic using a traffictrace application and
file.  I know that the file must be in binary format with two 32bit fields
(the first field in microseconds for interpacket transfer time, and the next
in bytes for packet size).  I have a java program that generates the packets
and writes them to file in binary string format (tobinaryString() : Integer
class).  I used the BufferedWriter and FileWriter to write the output.
Then, I convert the output to binary using ascii2binary (a command-line
linux program).  Every time I look at my output changed to binary, there is
barely any output written to it.  I have done this many times.  First few
times, I simply had my java program write the fields without expressing them
as a binary string (tobinaryString()).  At first I would get this error
"read failed" and NS would run my tcl script without generating any packets
for the node that with the traffictrace application.  I know that this means
that NS thinks my file has no elements or is null.  Now since I use
ascii2binary, I don't get that anymore.  Before using ascii2binary, I just
had java's toBinaryString().

I have tried using the example-trace file included in the source code.  It
works, and when I look at its fields (I used ascii2binary's binary2ascii
command), there is a lot of output in the file.  My output files barely have
anything written in them.  My output files look fine in ascii format,
though.

I have tried to use the hack to ns that allows for ascii traffictrace
files.  I found this on the ns-users mailing list.  It didn't work, so I am
not using it anymore.

My question is that I don't know how to create a traffictrace file that is
successfully read by NS.
Should I use another method to write to my output in java (BufferedWriter,
FileWriter)?  Should I use another language?  I appreciate your feedback,
thanks.
