A Trust based Secured Source Routing using Fuzzy logic rules Prediction in Mobile Ad Hoc Networks

Abstract

Abstract-In mobile ad-hoc network, nodes cannot rely on any fixed infrastructure for routing purposes. Since MANET routing is a cooperative process where route information is relayed between nodes, any secure routing mechanism must evaluate the trustworthiness of other nodes. In this research work, an Enhanced Trust-based Secure source Routing (ETSR) protocol is proposed. ETSR has considered an adaptive trust level classification of nodes by considering the trust values of both the individual nodes and the average trust values of all the nodes in the network. By the way of considering the u trust values of the intermediates nodes to compute the route's trust, it overcomes the problem of the routing cache. The proposed ETSR gives better results in terms of packet delivery ratio, average end-to-end delay and control overhead compared to the existing TSR and AODV protocols.
