In P2P network the resource search mechanism in regard to trust-reputation

To the problem of hostile service brought by node anonymity in P2P system, this thesis proposes a reputation aware resource finding algorithm. This algorithm is based on routing indices (RIs) algorithm and adopts the conception of reputation to efficiently restrain the deceiving behavior of hostile nodes in P2P system and reduce the messages load in the system, which can ensure the reliability and safety of the services. Simulation results show that the resource search schemes presented in this thesis not only reduce the searching cost and decrease the latency to locate resources in P2P system effectively, but also provide content-based query and ensure the safety of the whole system.
