基于社区多角色的结构化P2P网络查询技术研究

In this paper, a new query algorithm is proposed for a new structured P2P network model based on community and multi-role, that is, the iterative extended query algorithm. The algorithm uses the feedback mechanism, statistical information of the results has been returned back to the front query Q, to guide outward route strategy for Q. This paper first describes the query algorithm, then compares and analyzes it with Chord network, finally, simulates and verifies them using P2Psim. Simulation results indicate that good stable performance of the network model, resource query quickly, less traffic volume and the better results.
