Research on Multi-path Secure Routing Protocol Based on Friend Evaluation Model in Ad Hoc Networks

Because of the dynamic change of network topology and the open wireless channel, the Ad Hoc networks is more vulnerable to security attacks and paths are easy to break. In order to solve these problems, this paper proposes the Friend evaluation Multi-path Secure Routing Protocol (FSMSR) based on DSR protocol. FSMSR protocol can set up multiple node-disjoint paths through a route discovery process for every business connection by using multi-path mechanism and can detect and isolate malicious via friend evaluation model. The simulation shows that FSMSR protocol not only can improve the fault tolerance and robustness of the network, more can enhance the security of the network.
