| 摘 要： | 结合经济学上的博弈论知识来分析P2P网络中的信任问题,把节点之间的信任关系用博弈模型来分析,考虑节点之间并不清楚彼此之间的博弈关系会持续多久的重复博弈情形,然后通过调整节点策略的支付来分析使P2P健康有序发展的措施,最后通过仿真工具Gambit来验证该博弈模型.

| Abstract: | With the wide application of P2P technology,we must pay attention to trust problem in P2P networks.The knowledge of game theory is used to analyze the issue of trust in P2P networks by analyzing the trust relationship between nodes with the game model.This paper considers the repeated game situations that the nodes do not know how long the relationship between them will last,and then the strategies to make healthy and orderly development of P2P networks are analyzed by adjusting the payment of the node.Finally,the simulation tool named Gambit is used to verify this game model. |
