Controlling Model for the Hotspots in Peer-to-Peer Networks

Hotspots could degrade the performance of peer-to-peer (P2P) systems and add vulnerability to the system. This paper researches into the hotspots in P2P network, and present a new method to avoid generating the hotspots in the network by controlling the logical topology structure of P2P network. We firstly introduce the controlling ideas about seeking for spare nodes of the hotspots and distributing them into super-cube structure. Then, we disclose and interpret the controlling model, and give out the controlling algorithm. Finally, we validate our controlling model via simulations and the simulation results demonstrate that our work is effective to control the hotspots in P2P network. Thus, this model can improve the network competence to defend against coordinated attacks, promote the network robustness, and ensure the network would develop continually and healthily.
