Network Simulator version 2 (NS-2) is a discrete event, object oriented simulation tool to simulate and analyze dynamic nature of communication networks. NS-2 is an open source to develop new protocols and functions. It provides supports for Transmission Control Protocol/Internet Protocols (TCP/IPs) and many standard routing protocols for wire and wireless networks. In NS-2 many protocols have been implemented at various layers of TCP/IP protocol suite to provide different functionalities but none provide the security functions. This paper addresses this issue by adding new security module or protocol in NS-2.
