Abstract

In the unstructured peer-to-peer networks, the network topology and the placement of files are largely unconstrained. Gnutella is one of the prominent unstructured P2P networks. The primitive search in Gnutella is flooding-based search and the search region is constrained by TTL value. The scheme produces too much traffic though with limited search region. In addition, many of the peers in Gnutella are free riders, which waste too much traffic without contribution. In this paper, we propose several retrieval schemes to unstructured P2P network to extend the search region but reduce the search traffic, and also balance the network load, so that can acquire the whole networks scalable.
