How to Install and Run Network S…

Abstract : NS2  widely uses in network simulator. Toady let's install it.

Introduce : Ns is a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.


I need to do some experiments in NS2 and I download 2.3.5 version to install it.

Next some steps:
1. install some .dep :
$ sudo apt-get install build-essential
$ sudo apt-get install tcl8.5 tcl8.5-dev tk8.5 tk8.5-dev
$ sduo apt-get install libxmu-dev libxmu-headers

2. download /ns-allinone-2.35 from ns2 website(http://www.isi.edu/nsnam/ns/) and decompress it.
$ tar xvfz ns-allinone-2.35.tar.gz

3. enter ns-allinone-2.35 dir and tpye : sudo  ./install
when it has done, it print some information on monitor.




Now that NS2 is installed, there are some environment variables that need to be added to your profile. This can be done by editing the .bashrc file. Be sure to change “/path/to” to the path of where you have extracted NS2.

4. gedit ~/.bashrc to set the environment.

export PATH=$PATH:/path/to/ns-allinone-2.35/bin/path/to/ns-allinone-2.35/tcl8.5.10/unix:/path/to/ns-allinone-2.35/tk8.5.10/unix

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/ns-allinone-2.35/otcl-1.14:/path/to/home/nick/my_project/ns2/ns-allinone-2.35/lib

export TCL_LIBRARY=$TCL_LIBRARY:/path/to/ns-allinone-2.35/tcl8.5.10/library

5. You need to validate NS2 to check if everything is ok but beware that it will take lots of time:
cd ns-2.35 then ./validate and tpye ns
