Colluding Detection of Misbehaving Nodes in MANET?

With the increasing popularity of portable devices, wireless ad-hoc networks have been widely used to achieve better connectivity at places where an infrastructure is not immediately available or cannot be directly used. Its infrastructure less property and the easy deployment along with the self-organizing nature makes them useful for many applications. Nodes in MANET are with limited battery power and resources. Where few nodes behaves selfish to save their resources by expecting services from other neighboring nodes but refusing to provide any service to its neighbors or misbehaves by colluding, since routing requires cooperation of nodes it is highly important to provide incentives for them to cooperate. There exists extensive work in Mobile Ad hoc Networks (MANETs) on security measures as well as correctness of the estimation of the position of a node despite attacks from adversaries.
