The characteristics of dynamic, heterogeneity and limited resources of peers result in the existence of selfish behavior in MP2P network, which affect the network performance. To improve the performance of MP2P, a trust management model for peer reputation is established based on multiple-fuzzy theory in this paper. Direct trust, indirect trust, residual energy and active degree of peers are used as the fundamental variables and their weights are determined by using fuzzy theory, and then the reputation of peers is calculated. Peers with high reputation are allowed to participate in the communication and peers with low reputation are not allowed. The experimental simulation results show that the model not only effectively improve the malicious peer detection rate and the query hit rate but also reduce the Cx of the network.
