Assessment of Node Reputation in MP2P Based on Fuzzy Comprehensive Evaluation

Although many efforts have been made to study the reputation evaluation of node performance in Mobile Peer-to-Peer Networks (MP2P), the existing methodology of node reputation evaluation are not applicable to the scenarios in dynamic networks. To improve the performance of MP2P, in this study, we develop a new evaluation of node reputation by combining an analytic hierarchy process with a fuzzy comprehensive evaluation technology. The reputation of nodes is calculated using a membership function to account for direct and indirect trust, residual energy and fuzzy comprehensive evaluation. The experimental results show that the proposed method is not only robust in delivering a ratio of packet, but also reduce the average latency and overload ratio in MP2P environment.
