Simulation study for a secure routing protocol for wireless mobile ad hoc network

Mobile ad hoc Network (MANET) is a special type of mobile wireless network where a collection of mobile network devices form a temporary network without any aid of an established infrastructure. Security issues put special challenges in MANET routing protocol design. This project focuses on the simulation study for security of routing protocols for MANET, and particularly on the improvement of Dynamic Source Routing Protocol (DSR) security. What we have done in this project is to implement and design a system to improve the security routing for the existing DSR protocol by introducing the concept of trust value, the selection of a secure route will be based on these trust values. Analysis of the security issues caused by the malicious attacks against the DSR protocol are presented to identify how and where to incorporate the trust value in the protocol. Different simulations are performed on the NS-2 network simulator to evaluate the performance impacts of applying trust value based route selection to the DSR protocol. The results of these simulations are then analyzed and presented.
