摘要
P2P网络中的节点由于固有的理性将产生个人利益与系统性能相冲突的搭便车行为,从而极大地降低网络的性能和效用。在社会规范的基础上结合联合抵制敌我规则的思想,建立了一套应用于P2P网络的社会规范准则模型,该模型惩戒违反社会规范准则的节点,激励节点选择合作策略,并通过博弈收益分析给出模型均衡于合作策略的条件。仿真实验结果表明,该模型能够有效地激励节点协作和抑制节点搭便车行为。
Because of the nodes inherent rationality,P2P network system will generate the free-riding behavior that will cause the conflict between personal interests and system performance.This kind of behavior will greatly reduce the network efficiency and utility.A set of social norm model applied in P2P networkwas established based on the social norm in combination with the ideology of boycott.This mode can punish the nodes that have violated the social norm and stimulate nodes to select cooperation strategy,generate the condition of the balance of cooperation strategy through game revenue analysis.The results of the simulation experiment show that this model can both promote the node collaboration effectively and inhibit the free-riding behavior.
