Peer-To-Peer (P2P) networks establish loosely coupled application-level overlays on top of the Internet to facilitate efficient sharing of resources. They can be roughly classified as either structured or unstructured networks. Without stringent constraints over the network topology, unstructured P2P networks can be constructed very efficiently and are therefore considered suitable to the Internet environment. In recent year's peer to peer system have been evolved in all kind of areas. Unstructured peer to peer has been preferred for most of the application to share file among them. But searching or locating a peer or file in unstructured peer to peer system is a tedious process. That is the existing flooding mechanism reduces the efficiency of unstructured p2p networks.
