NS2 (Chung 2011) is a network simulator built using discrete events, developed at Berkeley University of California, and it simulates a variety of IP networks (Fall and Varadhan 2008). The simulator benefits from implementations of the TCP and UDP protocols, typical behavior of traffic sources such as FTP, Telnet, Web, CBR, and VBR, router queue management mechanisms such as DropTail, RED, and CBQ, routing algorithms such as Dijkstra, and many more. NS2 also implements multicasting and some MAC level protocols for LAN simulations. The current version of NS (version 2) is written in C++ and OTcl (Tcl scripting language with object-oriented extensions developed by MIT).
