| 摘 要： | P2P网络中集散节点的存在会导致整个系统的抗协同攻击能力大大降低,增加网络的脆弱性.对目前P2P网络中集散节点现象进行了研究,阐述了对集散节点进行层次化处理的控制思想,提出了一种全新的通过控制P2P网络的逻辑拓扑结构来避免集散节点形成的思路,给出了控制模型以及实现控制模型的具体算法,并对算法进行了复杂度分析,最后通过仿真证明了本控制模型能有效控制网络中集散节点的形成,所以本控制模型能提高P2P网络抗协同攻击的能力,增强网络的健壮性,从而达到保障P2P网络可持续健康发展的目的.

| Abstract: | This paper researchesd into the hubs in P2P network,and presented a new method to avoid generation of the hubs in the network by controlling the logical topology structure of P2P network.It firstly introduced the controlling ideas about hierarchizing the hubs.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.The simulation results demonstrate that the work is effective to control the hubs in P2P... |
