摘　　要：P2P技术是当前研究的热点方向,众多科研机构和企业加入其中,取得了令人瞩目的研究成果。由于受到移动网络自身特点制约,一些在其他网络中应用良好的技术并不一定适合移动P2P网络。提出一种基于移动P2P网络拓扑生成方法,该方法通过改进Chord算法的方法生成覆盖网网络拓扑,并提出了一种处理节点移动的方法。实验表明,该方法在降低覆盖网平均时延的同时,显著提高了网络的搜索能力。P2P technology is the focus direction of current research,with many research institutions and enterprises joining in,who have made remarkable achievements.Due to Constrained by its own characteristics of mobile network,the good technology of some other network is not suitable for mobile P2P network.This paper presents a method of generate P2P topology based on mobile network.We use this method to generate overlay network topology by improved Chord algorithm,and propose a method of process movement of nodes.Experiments show that the method can obviously reduce the average delay of overlay network,significantly improve the network＇s search capabilities.
