Selfish Dynamic Punishment Scheme: Misbehavior Detection in MANETs Using Cooperative Repeated Game

A Mobile Ad Hoc Network is a self-organized and infrastructure-less and dynamic network. In this type of networks, nodes organize themselves in a non-centralized form where additional effort is applied on network members. Hence, nodes in the network attempt to maximize its own benefits and saves its own resources in a form called rational behavior. Thus, selfish behavior arises as a problem that may cause a severe fault for the network and highly affects the network functionalities and performance. There is a need to bring a suitable punishment method for this kind of behaviors. We propose a slave mode selfish dynamic punishment scheme, using cooperative repeated game to avoid selfish behavior in Mobile Ad Hoc Network, and motivate selfish nodes to cooperate. The scheme is used to pertain a cooperative punishment from all network nodes, to exhaust the punished node which can stimulate this node to cooperate with other members.
