Abstract
Abstract The research of retrieving data in peer-to-peer (P2P) systems has become more and more important in many research communities nowadays. In order to search the resources in P2P systems, it is required to keep the global information that is usually maintained in few central servers; however, the maintenance overhead is relatively severe. In this work, we propose a framework that can distribute the global information in P2P systems with minimum maintenance overhead. By distributed the information in P2P systems, the framework can expedite the query processes and reduce the traffic load. The experimental results show our framework outperforms other methods in traffic and accuracy.
