摘要: 基于指针推进机制的层次移动IPv6方案未考虑接入路由器(AR)间的距离对切换性能产生的影响,针对该问题提出一种优化方案OPF-HMIPv6。OPF-HMIPv6首先比较AR间和AR与移动锚点(MAP)间的距离,优先向MAP进行注册,而不是直接向AR注册构建指针链。仿真结果表明AR与MAP间的距离大于AR间的距离时,OPF-HMIPv6比HMIPv6至少减少了39%的注册延迟,证实了该方案在减少绑定更新导致的开销上的有效性,提高了域内切换的效率。

Abstract: In the pointer forwarding schemes of Hierarchical Mobile IPv6 (HMIPv6), the influence of the distance between the Access Routers (ARs) on the handover performance has not been taken into consideration. To solve this problem, the optimization of intra-MAP (Mobile Anchor Point) handover in HMIPv6 based on pointer forwarding (OPF-HMIPv6) was proposed. The OPF-HMIPv6 compared the distance between ARs with the distance between AR and MAP firstly and gave priority to registering to MAP, rather than built a pointer chain immediately by registering to AR. The simulation results have shown that OPF-HMIPv6 can decrease the registration cost by 39% compared to HMIPv6 when the distance between AR and MAP is greater than the distance between ARs, which proves that the optimization reduces the overhead caused by the binding update and improves the efficiency of the intra-MAP handover.

Key words: Hierarchical Mobile IPv6 (HMIPv6), Mobile Anchor Point (MAP), intra-MAP handover, pointer chain, binding update cost, register
