Dynamic sharing of files from disconnected nodes in peer to peer systems

Most businesses collect and store sensitive information about their work or related like project documents, audio data, video data etc. while sharing files in peer-to-peer system dynamically peer nodes can add may delete. Peer-to-Peer file sharing using P2P application architecture. Shared files will move between different nodes. P2P technology is using by popular services like Napster, Bit Torrent, etc. So, here sharing a number of files, and requesting from one peer to another peer there may be losing of files or data. Because dynamically peer nodes may join and leave in the peer network. In this scenario there may be a chance of lose of file or data while sharing. This paper gives some solution to the above problem.
