Abstract: In order to motivate selfish nodes to forward data in wireless mesh networks, through analyze the reason and object of the nodes selfish behavior. Comparison four types of incentive mechanism of the nodes selfish behavior in wireless mesh networks. The discussion of game theory in wireless mesh networks and the theoretical analysis of repeated game theory are another emphasis. An incentive mechanism is proposed combined game theory and reputation ~or the selfish behavior of nodes. The simulation results show that the strategy not only reduces the complex of the reputation but also can effectively motivate more selfish nodes forwarding data which improve the overall performance of the wireless mesh networks.
