HI , i suggest to you install ns2 on any environment related to linux such as ubuntu and there is some steps must be followed to run ns2 , and you must have internet on the pc that download ns2 on it here the steps :- First, we download the ns-2 all-in-one file [54.4 MB]. $ wget http://nchc.dl.sourceforge.net/sourceforge/nsnam/ns-allinone-2.34.tar.gz$ tar -xzvf ns-allinone-2.34.tar.gz$ cd ns-allinone-2.34$ sudo apt-get install build-essential autoconf automake libxmu-dev$ ./install If your ubuntu version is 9.10, you must change the variable of environment CC $ export CC=gcc-4.3 Set environment variables $ gedit ~/.bashrc Add the following lines to the end of the file. Remember replace "/your/path" by the folder where you have stored extracted the ns-2 file (For example, if your Linux account name is purple, and you have extracted the file to your home directory, you have to change /your path to /home/purple) # LD_LIBRARY_PATHOTCL_LIB=/your/path/ns-allinone-2.34/otcl-1.13NS2_LIB=/your/path/ns-allinone-2.34/libX11_LIB=/usr/X11R6/libUSR_LOCAL_LIB=/usr/local/libexport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB # TCL_LIBRARYTCL_LIB=/your/path/ns-allinone-2.34/tcl8.4.18/libraryUSR_LIB=/usr/libexport TCL_LIBRARY=$TCL_LIB:$USR_LIB # PATHXGRAPH=/your/path/ns-allinone-2.34/bin:/your/path/ns-allinone-2.34/tcl8.4.18/unix:/your/path/ns-allinone-2.34/tk8.4.18/unixNS=/your/path/ns-allinone-2.34/ns-2.34/NAM=/your/path/ns-allinone-2.34/nam-1.14/PATH=$PATH:$XGRAPH:$NS:$NAM Ensure that it immediately takes effect: $ source ~/.bashrc Note: the previous step is important; else you cannot successfully run ns-2. (Alternatively, you may have to restart your X-windows, that is logout, and then login, or restart your computer.) Now, the installation has been completed. Try: $ ns The "%" symbol appears on the screen. Type "exit" to quit. Validation To run the ns validation suite: $ cd ns-2.34$ ./validate
