A load-balanced cooperation stimulation mechanism for selfish behavior of nodes in Wireless Network coding

Wireless Network coding requires cooperation among nodes, whereas selfish behaviors of nodes result huge decline in network performance. How to stimulate nodes to cooperate is a hot topic in wireless network coding theory. The paper addresses issue of cooperation in unicast network coding via a game theoretic approach. Considering the realization of network coding over fading channels, a load-balanced cooperation stimulation mechanism based on repeated game theoretic model is proposed. Theoretic analysis and simulation results show that our scheme can stimulate nodes to cooperate and achieve good load balance of network which brought by selfish behaviors of nodes.
