%X In order to solve free rider and tragedy of the commons problems in peer-to-peer(P2P) systems,this paper proposed a novel incentive based on game theory.While trying to maximize its own utility subjected to individual rationality,every peer allocated bandwidth resources efficiently according to competing peers' contribution values to maximize the social utility.The simulation result shows that the incentive increased the social utility of the whole P2P system rapidly and incentive every peer to share resources effectively.
