An effective neighbor peer selection mechanism for peer-to-peer networks

In this paper, a novel peer-to-peer (P2P) neighbor selection mechanism was proposed to enhance the efficiency of the file sharing process in P2P networks. In the mechanism, a modified and well-designed neighbor peer selection approach was introduced, which selects the neighbor peer based on the weighted value it holds. The weighted value includes several factors, such as the trust value, the number of good uploads, the number of good response, the number of malicious response, the number of bad uploads, the time-related degree. With the weighted value, the request peer may select some proper neighbor peers for forwarding its query messages, and then enhance the performance of the P2P networks. The detailed experimental results show that the proposed mechanism if efficient and useful for the dynamic P2P networks.
