Selfish attack detection in mobile Ad hoc networks

Combine effort of nodes in Mobile Ad hoc Network makes it more powerful. But supporting a MANET is a cost-intensive activity for a mobile node. Route discovery and packets forwarding consumes bandwidth and energy. One such routing misbehavior of node is some nodes may be act as selfish by taking part in route discovery and maintenance process, but deny forwarding the packet. Such type of misbehavior reduce packet delivery ratio and also degrade system performance in terms of power and bandwidth. MANETs is lack in centralized monitoring and infrastructureless behavior makes it more vulnerable to attack, and difficult to detect selfish node effectively. This paper surveys existing & latest developments in selfish attack detection system in MANETs. Based on existing study drawbacks, we have proposed assignment based Social Selfishness detection technique in mobile ad hoc networks. Finally, we conclude this some future work as a simulation in network simulator 2.
