A Proxy Mobile IPv6 Based Global Mobility Management Architecture and Protocol

This paper specifies a global mobility management architecture and protocol procedure called GPMIP, which is based on Proxy Mobile IPv6. In GPMIP, mobility management is performed by the network entity rather than individual mobile nodes. The benefit is the elimination of the wireless link data delivery tunnel overhead between a mobile node and the access router. To compare with the well known Hierarchical Mobile IPv6 mobility management protocol, the location update, packet delivery, and total cost functions generated by a mobile node during its average domain residence time are formulated for each protocol based on fluid flow mobility model. Then, the impacts of various system parameters on the cost functions are analyzed. The analytical results indicate that the proposed global mobility management protocol can guarantee lower total costs. Furthermore, a qualitative comparison between GPMIP and some other global management protocols is also investigated.

本文详细阐述了一种名为GPMIP的全球移动性管理架构和协议流程，它基于代理移动IPv6。在GPMIP中，移动性管理由网络实体而非单个移动节点执行。其优点是消除了移动节点和接入路由器之间无线链路数据传输隧道的开销。为了与著名的层次移动IPv6移动性管理协议进行比较，基于流体流动移动性模型，针对每种协议制定了移动节点在其平均域驻留时间内产生的位置更新、分组传递和总成本函数。然后，分析了各种系统参数对成本函数的影响。分析结果表明，所提出的全球移动性管理协议能够保证更低的总成本。此外，还对GPMIP和其他一些全球管理协议进行了定性比较。
