Executive Summary

A MANET (Mobile Ad-hoc NETwork) is a self configuring system of mobile nodes connected by wireless links. MANETs are self-configuring and decentralized without having a fix infrastructure. In such a network each node acts as an end-system as well as a relay node (or router). Most of the routing algorithms designed for MANET such as AODV and DSR are based on the assumption that every node forwards every packet. But in practice some of the nodes may act as the selfish nodes. These nodes use the network and its services but they do not cooperate with other nodes.
