Any suggestions? i wiil be thankfull . -- View this message in context: http://old.nabble.com/changes-in-AODV-cc-file.how-will-it-effect-tp27735264p27735264.html Sent from the ns-users mailing list archive at Nabble.com.
[ns] ns-2 FAQ
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.

Hey, Are there any resources relating to the use of Wireless Sensor Network simulation using NS-2? Thanks, Jethro
[ns] Address Node
Hello Everybody! I have a little question about address node. For example: set MH [$ns_ node 1.0.1] set node_(0) $MH set HAaddress [AddrParams addr2id [$HA node-addr]] [$MH set regagent_] set home_agent_ $HAaddress In this TCL lines, I assign an address to my mobile-node. I would like to know where this value is stored in the source code. Moreover I need to know the field in the packet (header) where the address is wrote. Thanks :)
[ns] multiple classifiers and routing modules
Hi all, I was wondering if it was possible to have more than one classifier (like hash/fid and hash/dest) in one routing module ? If not do i have to implement one classifier per routing module ? What are the differences and the uses between the hook for the classifiers and the next_rtm for the routing modules ? How to use a routing module more than once in the same node ? and link them ? Thanks for your help ! Aurélien Lafranchise
[ns] 802.11: mixed dcf/edca scenario
Hi. I have to simulate an IEEE 802.11 scenario with both DCF (802.11-legacy) and EDCA (802.11e) stations; adhoc topology should suffice. I searched for this at http://www.isi.edu/nsnam/ns/doc/node193.html and I quickly looked at related ns-2 examples in cvs. It looks like 802.11e (EDCA) is not supported (and so there is no possibility to simulate a mixed DCF/EDCA scenario). I know about the out-of-tree ns-2 802.11e patch at http://www.tkn.tu-berlin.de/research/802.11e_ns2/ but as far as I know it does not let you simulate both DCF and EDCA stations in the same scenario. I also looked at ns-3 wifi model http://www.nsnam.org/doxygen-release/index.html It looks like QoS and non-QoS MACs (i.e. EDCA and DCF) are well integrated in ns-3. Even if I didn't test it, it should be possible to simulate a mixed DCF/EDCA scenario in ns-3. Do you know if it is possible to simulate a mixed DCF/EDCA in ns-2? Any comments are welcome.

[ns] Overhead packets versus ART
Hi, Please, I need to a script awk to calculate with ns2, Overhead packets in 2 minutes by increasing ART (3s, 12s, 30s, 60s, 120s) we note that: ACTIVE_ROUTE_TIMEOUT (ART). The ART is a static parameter that defines how long a route is kept in the routing table after the last transmission of a packet on the route. The best Lyx
[ns] Variable values always revert back (or never change)
Hi,
I am noticing something weird. I tried implementing set and get function for
variables like RXThresh_ and Pt_ defined in wireless-phy.cc. These functions
were implemented in ns-mobile.tcl so that I can change these through the
node class. When I try to change the values, I can observe that the call is
happening to the lines of code written in wireless-phy.cc but when I do a
get, the value is not changed. So for instance, I added something like this
inside wireless-phy.cc::
if(strcasecmp(argv[1], setRXThresh_) == 0) {
RXThresh_ = atof(argv[2]);
printf(Set the RXThresh to %.12f\n, RXThresh_);
return TCL_OK;
}
I can see the printf statement printed but the effect is not taking place.
Does anyone know what could be happening here?
Thanks,
John
[ns] probmlem in wired-cum-wireless topology
Hi I have a problem in wired-cum-wireless topology. I tried to run wireless3.tcl in Marc Greis' Tutorial: http://www.isi.edu/nsnam/ns/tutorial/ In this topology, the traffic source is a wired node and the sink is a moving wireless nodes which goes from the domain of a base station to the domain of another one. But when I put the traffic source on the wireless node and sink on a wired node, it seems that moving wireless node doesn't move. any idea? Thanks Saeideh
[ns] Satellite error model problem
Hi all, I tried to use error model in the ns2.XX/tcl/ex/sat-iridium.tcl on the receiving terminal.I used the error model code as described in the ns manual like the following: set em [new ErrorModel] $em unit byte $em set rate_ 1e-7 $em ranvar [new RandomVariable/Uniform] $n101 interface-errormodel $em When I checked the trace file, there's no event begin with e or d which indicate the error event. In addition, there seems no different in term of the number of trace lines packet id eventhough I increase the error rate... I expected that there should be some differences in the trace file in term of the type of event occurred and also the number of transmit received packets please help regarding this matter... Lukman
[ns] running wireless simulations in 3D scenario using ns-2?
Hi all, I am a beginner of ns-2. I did simulation of wireless networks using the mobility model in ns-2. I am now in a project which needs to simulate a wireless network in 3D scenario, e.g. wireless communications between a helicopter and a ground vehicle. Does ns-2 support such kind of simulation? If not, is there any other software which can do that? Any suggestions would be appreciated. Thanks. Regards, Hua

Dear Everyone, I am looking for implementing sub-carriers in WSN. Any advise or assistance is most appreciated. Thanks and Regards.
Re: [ns] WSN NS-2 Resources
Hello, To simulate WSN in NS-2 either you can use Mannasim patch with ns2.29 or you can use NRL Sensorsim patch with ns2.26 or ns2.27. Following are some of the useful links: NRL Sensorsim details: http://mohittahiliani.blogspot.com/2010/02/installing-ns226-with-nrlsensorsim-on.html Mannasim patch: http://www.mannasim.dcc.ufmg.br/ Hope it helps.
