摘要:
 PMIPv6协议是MIPv6协议的扩展,是一种基于网络的移动性管理技术。在PMIPv6协议中,由网络负责探测节点的移动路径并初始化所必须的移动信令,MN不参与切换过程,能量消耗低,但是PMIPv6依赖于一个独一无二的处于网络中央的本地移动锚点( LMA),容易导致瓶颈问题,且带来切换时延长、通信路径非最优等问题。基于此,提出了一种基于PMIPv6的移动性管理方案,使用簇对移动接入网关(MAG)进行分组。在每个簇中选举出一个头移动接入网关(HMAG)作为簇头,由HMAG代替LMA负责执行本簇内的移动切换以及最优化数据通信路径,这样就减少了LMA的负载,延长了网络寿命。分析及仿真结果表明所提方案与PMIPv6相比在总开销、LMA负载等方面都有较大的改善。
Abstract:
 PMIPv6 is an extension of MIPv6,it is a network-based mobility management technique. In the PMIPv6,the tasks of detecting the path of nodes mobility and initiating the required mobility signals are completed by the network. Thus the MN don’t participate in the process of handoff,the energy consumption is lower than MIPv6. But PMIPv6 depends on a single LMA (Local Mobility Anchor) which is in the center of the network,which leads to bottlenecks easily,and brings the problem of long handoff latency and non-optimized com-munication path. Considering the problems above all,propose a mobility management scheme based on PMIPv6. The proposed scheme u-ses cluster to group the MAGs ( Mobility Access Gateways) ,and selects a HMAG ( Head Mobility Access Gateway) as the cluster head in each cluster. The HMAG performs the intra-cluster handoff process and provides an optimized data communications path instead of LMA. Thus the design can reduce the LMA load and prolong the lifetime of the network. The analysis and simulation results show that the proposed scheme has a great improvement on total cost and LMA load compared with PMIPv6.
