摘　　要：针对传统网络技术不适合移动通信且移动IP和SIP有单失效点固有缺陷的问题,文章提出了一种基于对等网络的IP网络分层移动性管理方法。该方法首先将问题结构定义为本地接入域网络和Internet全局网络两层模型,使用本地和全局两级覆盖网来处理该模型中接入网内的水平切换和跨接入网的垂直切换,并使用HIP协议来解耦静态主机标识和实际的网络位置。文章通过仿真实验指明将对等网络与移动性管理相结合的方法可以有效改善网络的可扩展性,并且信令开销和时延增加较少,此外HIP协议还为应用提供了透明的移动性和安全性的支持。Because that traditional network technology does not adapt to mobile communication and mobile IP and SIP have an inherent defect of single point of failure, a hierarchy mobility management method for IP networks based on P2P is brought out in this paper. First, it defines the problem structure of two-level model. One is local access domain network; the other is Internet global network. Second, it uses two-level overlay structure in this model to deal with horizontal handover in access network and vertical handover across access networks. Third, it also uses Host Identity Protocol （HIP） to uncouple static host identifiers from the actual network locations. The simulation experiment specifies that the combination of P2P and mobility management method can effectively improve network scalability and increase less signaling overhead and delay. Furthermore, the HIP also provides transparent mobility and security support for the applications.
