该文定义一种基于代理移动IPv6的全局移动性管理结构和协议,简称为PMIPGMM。在PMIPGMM中,由网络实体而不是移动节点完成移动性管理,另外消除了移动节点和接入路由器之间分发数据的无线链路隧道负荷。为与熟知的层次移动IPv6协议比较,基于液体流移动性模型,分别给出了每个协议下,移动节点在平均域停留时间内产生的位置更新、数据分发和总费用函数。分别研究了各种系统参数对费用函数的影响。分析结果表明所提出的基于代理移动IPv6的全局移动性管理协议可以保证低的总费用。
This paper specifies a Proxy Mobile IPv6 based Global Mobility Management architecture and protocol procedure, named PMIPGMM. In PMIPGMM, the mobility management is performed by network entity other than mobile node itself. The other benefit is the elimination of the wireless link data delivery tunnel overhead between the mobile node and the access router. To compare with well known hierarchical mobile IPv6 mobility management protocol, the location update, the packet delivery and total cost functions generated by a mobile node during its average domain residence time in each protocol are formulated based on fluid flow mobility model. Then, the impacts of various system parameters on the cost functions are analyzed, respectively. The analysis results indicate that the proposed proxy mobile IPv6 based global mobility management protocol can guarantees lower total costs.
