Distributed controlling model for hubs in P2P networks

This paper researched into the hubs in P2P networks, and presented a new method to avoid generating the hubs in the networks by controlling the logical topology structure of P2P networks. It firstly introduced the controlling ideas about distributing the hubs by using super-cube structure. Then, it disclosed and interpreted the controlling model, and gave out the concrete method to carry it out. Finally, it validated the controlling model via simulations and the simulation results demonstrated that the work was effective to control the hubs in P2P networks. Thus, this model could improve the network competence to defend against coordinated attacks, promote the network robustness, and ensure that the network would develop continually and healthily.
