| 摘 要： | 在借鉴博弈理论的基础上，结合P2P网络的特点，提出一种基于理性博弈的激励模型，并构建该模型的有限自动机。通过引入对自私节点的惩罚机制，制定相应的行为规则，激励理性节点为使其自身收益最大化向整个网络贡献资源。仿真结果与分析表明，该模型能有效地惩罚自私节点，威慑其放弃自私行为。 |

| Abstract: | The establishing of effective incentive mechanisms is one of methods to restrain the selfishness of nodes and improve the system usability of P2P network. The features of P2P network is taken into account, an incentive model for P2P network is proposed in this paper, which comes from rational game. This paper implements the finite state machine of the incentive model. Punishing mechanisms to selfish peers and some essential norms are introduced in this model, which stimulates rational peers to maximize their own utility and contribute their free resource. Analysis and simulation results testify that this model can effectively punish selfish peers, and make them drop selfish behaviors. |
