摘要
针对P2P网络中基于个体的信誉机制的弊端,设计了双层结构信誉模型,即基于组群的P2P网络信誉机制。该机制在"物以类聚人以群分"的管理思想基础上,通过计算同一组群内节点间的信誉值不同组群中节点间的信誉值,以及组群间的信誉值的方法,从而实现P2P网络的良性自治。该机制设计了不同的节点间信誉计算方法,以满足各种网络的不同特性需求。随后通过模拟实验,验证了该机制的可行性和高效性,并分析了该机制适用的网络容量。
To solve the problems of based-on-peer reputation system in P2P network, this paper designed a double-deck repu- tation model, called based on group reputation system in P2P network. With the thought of birds of a feather flock together, by calculating a node' s reputation of another node in the same group, a node' s reputation of another node in different groups, and a group' s reputation of another group, the system fulfilled the implementation of P2P network' s well self-management. The system used different calculation methods to meet different networks' various requirements. By the experiments, the sys- tem was proved to be feasible and efficient. Furthermore, analyzed the applicable capacity of the system.
