Combine effort of nodes in Mobile Ad hoc NETwork (MANET) makes it more powerful. But supporting a MANET is a cost-intensive activity for a mobile node. Finding routes and forwarding packets consumes bandwidth and energy. One such routing misbehavior is that some nodes may be act as selfish by participating in route discovery and maintenance process, but deny forwarding the packet. Such nodes routing misbehavior reduces the packet delivery ratio and wastes system resources such as power and bandwidth.
