Abstract

When a P2P client requests content it is difficult to diffuseits broadcast without causing a query explosion. By applyingpercolation theory to diffuse newly defined reverse-query messagesover the unstructured P2P network, we propose a novel informationdelivery network architecture built over the existing unstructuredP2P network. We analysed our algorithm and examine the validity ofour model, which will cover more than 80% of all the clients, byrelaying reverse-query messages under a probability as low as 10%.It is proven to be effective in reducing the total trafficgenerated by query propagation drastically. This architecture canbe applied to building content sharing networks over theunstructured overlay network.
