Approach:
NS-2 is an open source system that is developed using C++ and Tool Control Language TCL. Researchers can freely add new components to the system to server their own purposes. The latest version of NS-2 is version 2.28. Within this version, most of the standard protocols supported. You can find protocol from media access layer protocols such as CSMA/CD up to application protocols as FTP and HTTP. For routing protocols, there are unicast and multicast routing protocols for wire network and DSR, DSDV, AODV for wireless ad-hoc networks. Most of these protocols were developed by researchers and adopted into standard version of NS-2.
In order to experiment security features for network, we need to add security functions into NS-2. Of course for specific experiments there are specific requirements. The purpose of this project is only to illustrate a way to add security functions into NS-2
Our approach is to build a new protocol at network layer
