摘要： 根据进化博弈的观点，提出一种资源共享型P2P网络博弈激励模型。对P2P网络进行描述，并对节点的行为进行量化分析，建立节点资源访问的概率模型，给出共享型P2P网络中的个体模拟动态方程。在随机博弈收益矩阵的基础上，通过调整相关参数引导P2P网络向动态平衡的状态演化。仿真实验结果验证了该模型的可行性和灵活性。

Abstract: With the help of biological and economical research fruits, this paper analyses Peer’s behavior from evolutionary game theory so as to keep the P2P system dynamical balance. It describes the P2P network and quantifies Peer’s contribution. It proposes a probability model and introduced replicator’s dynamical equation. The incentive mechanism is set up by changing related parameters in random game payoff matrix. Simulation results indicate the model is practicable and flexible.

Key words: P2P network, evolutionary game, incentive mechanism, network model
