An improve AODV link prediction technique via detecting selfish nodes in MANET by using fuzzy logic

Mobile Ad Hoc Networks (MANETs) is a collection of mobile nodes connected with wireless links. A major challenge for these networks are due to their features of open medium, dynamically changing topologies, absence of centralized monitoring points, and lack of any clear lines of defence. All the nodes in MANET must co-operate with each other to route the packets. Cooperating nodes should trust each other. There are several protocols proposed based on the trust. Some trust management schemes have been proposed, to provide a general framework for trust evidence distribution or evaluation of link prediction in MANETs. However, these schemes cannot provide security against some attacks such as packet dropping by selfish nodes in the network. In this report, a new link prediction based approach has been proposed using fuzzy logic in evaluating trust for misbehavior detection of a selfish node in MANET.
