TSN: A Three-level SuperPeer Network for Enhancing File Sharing

We propose a three-level SuperPeer network (TSN) for file sharing built on a SuperPeer network. The TSN adopts a SuperPeer P2P network capable of providing file management and the structured P2P network capable of searching file as its basic structure. It is required to dynamically reconstruct its network topology according to changes in peer state and file hot. We propose an autonomic, distributed, and cooperative method to redistribute files dynamically among peers based on file popularity. In simulation experiments, we first set up a network topology that ensures reliable file search. This is carried out under the assumption that the load state of all peers in the network can be obtained in advance. The results show that the file searching in the TSN system is more efficient than in the SuperPeer system.
