An efficient message passing technique using route path information in unstructured peer to peer network

Peer-to-Peer overlay systems offer a substrate for the construction of large scale and distributed applications. The Peer-to-Peer technique is differentiated in to two major forms, Structured P2P and Unstructured P2P. In structured peer-to-peer networks, connections in the overlay are fixed. They typically use distributed hash table-based (DHT) indexing, such as in the Chord system. Unstructured peer-to-peer networks do not provide any algorithm for organization or optimization of network connections. Hence the functions like searching, querying etc. are mostly flooded. In this paper we propose a novel message passing technique in which each peer maintains the route path of the destination with in itself which uses this route path to send and receive messages. This method minimizes the packet flow in the unstructured P2P which occur during flooding technique. Keywords-Peer-to-Peer, Unstructured P2P, Routing.
