基于二阶声誉测度的自组织网络合作激励机制

将二阶声誉测度Standing应用到自组织网络的合作激励机制中,设计了一种基于Standing的包括服务和声誉管理的分布式合作管理协议,克服了间接互惠所面临的二阶搭便车问题.数学分析和模拟实验表明,在二阶声誉作用下,区分策略是演化博弈惟一的进化稳定策略,从而促进了用户的合作.同时,采用完全的分布方式所构建的可信第三方架构能够有效应对合谋、虚假的声誉反馈与声誉提供等欺骗行为.该合作机制在一般的动态环境中具有良好的适应性.

Cooperation incentive mechanism in self-organized network based on second-ordered reputation

By introducing second-ordered reputation,Standing,into the cooperation incentive mechanism in self-organized network,a distributed cooperation management protocol,composed of service management and reputation management,is put forward to solve the second-ordered free-riding problem in indirect reciprocity.Mathematics analysis and simulation show that discrimination strategy is the only ESS(evolution stable strategy) in evolutionary game with second-ordered reputation,which encourages cooperative behavior.On the other hand,the pure distributed infrastructure of trusted third part can resist effectively various cheats,including collusion,false reputation feedback or presenting.The incentive mechanism can adapt well in common dynamical environments.
