Abstract

The resource discovery algorithms in Peer-to-Peer networks are based on the assumption that reliable resources are provided by each peer. The feather that significantly contributes to the success of many P2P applications is dynamic, anonymity and self-organization. However, they also bring about some malicious nodes to provide untrustworthy and pseudo services. To address this problem, this paper introduces a robust and flexible reputation mechanism in unstructured P2P and presents the heuristicresource discovery algorithm based on reputation-aware to ensure that resource requester can obtain reliable resources and services. This new resource discovery algorithm can effectively suppress the deceptive and fake services of P2P network, improve the reliability and security and decrease network load.
