Abstract:In a real peer-to-peer(P2P)network,large amounts of network measurement results show that free riding is prevalent in almost all P2P reliable streaming media networks,which reduces the robustness,availability,service response speed,and lifetime of P2P reliable streaming media networks.Research of the reasonable and effective mechanisms to prohibit free-riders and incite selfish nodes to contribute more to the system has become an important direction for application research of P2P reliable streaming media n...
Keywords:peer-to-peer networks  free-riding  restrain and incentive mechanisms  game theory  Nash equilibrium
