WHAT IS NS-2?

ns (from network simulator) is a name for series of discrete event network simulators, specifically ns-2 and ns-3. Both simulators are used in the simulation of routing protocols, among others, and are heavily used in ad-hoc networking research, and support popular network protocols, offering simulation results for wired and wireless networks alike.

Both ns-2 and ns-3 are popular in research given their open source model and detailed online documentation

• ns-2 stands for Network Simulator version 2.

NS-2:

• Is a discrete event simulator for networking research

• Work at packet level.

• Provide substantial support to simulate bunch of protocols like TCP, UDP, FTP, HTTP and DSR.

• Simulate wired and wireless network.

• Is primarily Unix based.

• Use TCL as its scripting language.

• ns-2 is a standard experiment environment in research community.
