Investigation on Performance of Trust Based Model and Trust Evaluation of Reactive Routing Protocols in MANET

In this paper we investigate and implementing trust based route selection in mobile wireless ad hoc networks. A system that stores and updates trust values for nodes encountered in mobile ad hoc networks. Since a route consists of many nodes that are grouped, different strategies for evaluation of routes based of the nodes trust values have been designed and implemented. We apply trust based route selection to the DSR, AODV and DYMO Protocols, in order to secure the protocol and improve route selection, which can increase throughput in situations where malicious nodes are present in the network. To evaluate the performance impacts of applying trust based route selection in sending, receiving and forwarding of packets. The performance is calculated in terms of metrics like throughput, packet delivery ratio and average jitter. The evaluation of trusted AODV, DSR and DYMO with implemented trust has been done with the help of QualNet 5.0 simulator
