Abstract

Equal peers in peer-to-peer (P2P) networks may be drawbacks in term of bandwidth, scalability and latency of system. In this paper we use the super-peer model in order to query process in P2P networks. Each super-peer in this presentation utilizes the Hop-Count Routing Indices (HRI) technology to select the best neighbor super-peer. The latency of query process and the scalability of system is improved by using the HRI based search model. We evaluate the performance of this work by means of simulation based on GridSim tools which shows the efficiency of our approach compare to flooding method.
