Providing File Surveillance to Actively Search for Files by Querying Structured Peer to Peer Overlay Systems

In a peer to peer system searching a file in each and every node it is very difficult. These days everybody using file sharing, and video streaming. So here while sharing or downloading a file there may be loss of data in the file. To avoid all these problems I proposed a concept providing file surveillance to actively search for files by using query performance in structured peer to peer overlay systems. using querying performance in structured overlay peer to peer systems if any node is leaving dynamically data should not loss.
