Download and Installation of NS-2 in a Linux/UNIX environment NS2 is a network simulator program; it is freely available on the internet to download for academic research purpose. NS2 can be compiled and run both in a UNIX and under Cygwin for windows environment. It is an important to note that NS2 is fairly large and requires around 300 MB hard disk space for installation. In order to run and install NS2 you need a PC with a C++ compiler and UNIX operation system (FreeBSD, Linux, SunOS, or Solaris).
