Topological Optimization of Hubs in P2P Network

Abstract

Abstract-This paper further studied the hubs in P2P network, and presented a strategy based on hierarchical P2P network by controlling the logical topology structure and through enhanced mechanism to avoid the formation of hubs. It firstly introduced the idea of control model, and the specific implementation of control model .Then carried out complexity analysis of the algorithm. Finally, it validated the via simulations ,The simulation resulted that the control model of topology optimization could effectively control the formation of hubs, and improve the ability of P2P network anti-coordinated attack, thus effectively enhance network robustness and load balancing.
