Abstract

To improve unstructured peer-to-peer system performance, one wants to minimize the number of peers that have to be probed before the query is answered. In this paper, we propose a replication strategy with the consideration of heterogeneous resources among peers in the unstructured P2P system. In our strategy, the system copies the replication of the popular file to high capacity peers. Experimental result shows our replication strategy reduces the network traffic greatly, and improves the popular file availability effectively.
