Session Based Protocol: Data Sharing in an Overlay System

Overlay network such a network in which no existence of any server. It is recommended research spot for network architecture. There are various applications which can be deployed on this architecture. Overlay network is more reliable and efficient for sharing data. There are a variety of approaches exists which need to improve the overlay system efficiency. In overlay network instead of a centralized server every node has equal potential and priority. Peer’s age not fix in the overlay network node may leave or join network frequently. Paperaddresses the problem of extremely temporary populations in unstructured and loosely structured peer-to-peer (P2P) systems.In existing system query strategy is based on flooding where every query propagated to all achievable nodes inside certain area of network. This approach faces the limitation of scalability. In this paper, a session based approach for query supply, cashing and duplication is discussed. The problem of high temporary node in unstructured and loosely structured in P2P system can be solved by session based approach.
