In this paper we focus on replication method in unstructured Peer-to-Peer (P2P) networks. Most current replication approaches are designed for the structured P2P systems. The EAD is specific for the unstructured P2P network, but the replica utilization is low and has the bump problem. In order to acquire more replica utilization and search efficiency, we propose a decentralized replication methodsFTR. The proposed algorithm can calculate the real query flow of node according to the order of the node selected. Experiment on the simulation proves that our method can enhance search success rate and replica hit rate.

Content location in unstructured peer-to-peer (P2P) networks is a challenging problem. In this paper, the authors present a novel Interest-based Small World (ISW) network to address the problem, by constructing a cluster overlay in the unstructured P2P network based on the small world paradigm and user interest. There are many attractive properties of a small world network, such as low average hop distance and high clustering coefficient. Interest locality can improve the awareness of user’s indeed intentions. The authors’ scheme combines their advantage to create a better solution. The simulation results show that our scheme outperforms other schemes significantly.
