摘　　要：目前,多媒体业务在MANET中有很大的发展需求,在MANET上执行多媒体业务,一种可靠的方法是部署P2P应用,而实现寻址功能是实现P2P应用的基础性工作。利用P2P技术中基于分布式哈希算法的的寻址机制可以解决MANET中多媒体业务的的节点定位问题。但是由于传统的分布式哈希算法存在其逻辑拓扑与物理拓扑没有相应的匹配机制,MANET中节点的移动性的特点等,导致其无法直接应用于MANET,这将基于分布式哈希的P2P网络应用于MANET带来了巨大的挑战。文中对基于MANET的多媒体业务寻址方法进行了分析,并且通过文献调研法对基于Chord的MANET寻址方法研究进展进行了总结。At present,there is a great demand for multimedia services in MANET,and a reliable way to execute multimedia services on MANET is to deploy P2P applications,the implementation of addressing function is the basic work of P2P applications.The addressing mechanism based on the distributed hash algorithm in P2P technology can solve the problem of node location in multimedia services in MANET.But because there is no corresponding mechanism and MANET node mobility characteristics of logical topology and physical topology that the traditional distributed hash algorithm has,the traditional distributed hash algorithm can not be directly applied to MANET,which used P2P network based on distributed hash MANET has brought a huge challenge.In this paper,the MANET based multimedia service addressing method is analyzed,and the research progress of the MANET addressing method based on Chord is summarized.
