One Scheme for Cooperation Enhancement in Ad Hoc Networks

Mobile ad hoc networks (MANET) works properly only if the participating nodes cooperate in routing and forwarding. However, for saving battery life, the selfish node simply does not cooperate in network operation. So in this paper, we analyze the harm of selfishness behavior and its solution, and provide an improved scheme, which is based on trusty center server and neighbor monitor cooperative enhancing. It may solve the spoofing attacks caused by selfish nodes changing their identities. Finally, the simulation results conclude that this cooperation enhancement scheme is effective to solve the selfish nodes secure problem, and it is easy to be implement.
