Re: [ns] Fwd: Problem to run cbrgen.tcl

2011-09-01 Thread Arindrajit Pal 

I want to run cbrgen.tcl. I use appropriate command also. The error given me
is shown below.
*[arindrajit@localhost mobilitypatterns]$ ns
% ns cbrgen.tcl -type cbr -nn 70 -mc 10 -seed 1 -rate 1.0  cbr70
warning: using backward compatibility mode

*Now, kindly tell me what is the cause for the error? *

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.

[ns] [Help] Wireless multicast - in wireless mesh networks

Hello everyone,


I am trying to perform multicasting over wireless mesh networks. Does anyone
have any idea how to do it?
I would appreciate it if anyone could forward me to any text related to

Re: [ns] [Help] Wireless multicast - in wireless mesh networks

2011-09-01 Thread Manaswi Saha 

Hi,

Thanx for the reply.

I had seen this page. Most of them are for wired networks right? Won't there
be a difference in performing multicasting over wireless networks. I am not
sure about because I am new to ns2.

Also, how do i implement the same in a wireless mesh network? Ho*w *to
simulate wireless mesh networks?

Thank you.
