An Efficient Searching Scheme in Unstructured P2P Networks

摘要

Unstructured peer-to-peer (P2P) systems, due to their excellent support for content lookup and sharing, are creating a large proportion of network traffic in today's Internet. A P2P system typically involves thousands or millions of live peers in the network. In this paper, we propose and evaluate an efficient searching scheme in unstructured P2P networks. This scheme proposes a local adaptive routing protocol. This routing protocol adopts a simple scheme which driven by query interest among peers. We analyze this scheme's performance and present simulation results. Our simulation results demonstrated the benefits of the proposed system and show that the approach is able to dynamically group nodes in clusters containing peers with shared interests, at the same time, and organized into a community network.
