On the optimization of content publishing and search in peer-to-peer network - a location aware approach

With network pipes growing fatter, peer to peer systems are fast emerging as a viable alternative to the client-server model. One of the major problems in P2P networks is the efficient and fast content distribution and search. In this paper we investigate the problem of replicating content information among the peer nodes in a scalable manner using coordinate based placement such that an automatic identification of near by replica locator nodes is possible to improve the search latency when finding content sources. We also investigate the use of social groups as content information aggregators to facilitate faster and more accurate search. We try to improve the overall accessibility of content in the network by hierarchically distributing the content information. We show by way of simulation the improvement in performance of content location using the above methods.
