file sharing in less structured p2p systems

. ABSTRACT--Most of the file sharing n/w plays a major role in the current networking domain. On that the file sharing between the users is an important work takes place on those systems. When considering each of the system, the need is a performance improvement in the network. We finding the problem of highly transient populations in unstructured and loosely structured peer-to-peer (P2P) systems. In available system they consider the distributed system and causes collision while communication between the systems. But we consider centralized system and overcome the collision during file sharing and also the existing system drawbacks.
