The trust model of P2P service based on QoS

The current trust models for P2P network, are mainly focused on the trust of network nodes, most of which neglect the network service trust and don´t fully consider the attribute of service quality. However, the trust of network service is an important factor in P2P network. In order to ensure the trust of P2P network, this paper builds the P2P network service trust model based on QoS in view of P2P service, the model include the partial of directly interactive trust and recommendation trust by applying fuzzy mathematical method. Meanwhile, presents the solution algorithm for the trust of P2P service and then analyzes the validity of the service trust model by experiments.
