A Fuzzy-Based Trustworthiness System for JXTA-Overlay P2P Platform and Its Performance Evaluation Considering Three Parameters

The trustworthiness of peers is very important for safe communication in P2P system. The trustworthiness of a peer can be evaluated based on the reputation and actual behavior of peers to provide services to other peers. However, in order to decide the peer trustworthiness are needed many parameters, which make the problem NP-hard. In this paper, we propose a fuzzy-based peer trustworthiness system for JXTA-Overlay P2P platform considering three parameters: Actual Behavior Criterion (ABC), Mutually Agreed Behavior(MAB) and Reputation (R). We evaluate the proposed system by some simulations. The simulation results has shown that the proposed system has a good behavior.
