摘要/Abstract

摘要： 针对在分层移动IPv6(HMIPv6)中域内切换和域间切换的时延相差较大的问题，提出一种新的移动锚点(MAP)选择算法。在域内切换时继续使用HMIPv6，在域间切换时则采用一种基于预重复地址检测(DAD)的HMIPv6(D-HMIPv6)机制。D-HMIPv6通过引入一个同伴节点(PN)，进而帮助移动节点(MN)在域间切换时预先完成部分3层切换，以此来减少重复地址检测过程所带来的切换时延。网络仿真工具NS-2的结果表明，相比HMIPv6，D-HMIPv6把域间切换过程中的时延缩短了将近2s，有效地提高了对移动IPv6实时应用的支持能力。

Abstract: To deal with the big difference between inner-domain and inter-domain on handoff time delay of Hierarchical Mobile IPv6 (HMIPv6), this paper proposed a new Mobile Anchor Point (MAP) selection algorithm. When handoff happened on inner-domain, the Mobile Node (MN) continued to use HMIPv6, otherwise to use a new mechanism based on Duplicate Address Detection (DAD) HMIPv6, called D-HMIPv6. An element called Partner Node (PN) was introduced to help MN complete partial three layer handoff work in advance when it was in inter-domain, which reduced the time delay by DAD. The results of the network simulation tool NS-2 show that, compared with the HMIPv6, D-HMIPv6 reduces the inter-domain handoff time delay nearly by two seconds, and improves the ability of supporting mobile IPv6 in real-time.

Key words: inter-domain handoff, Mobile Anchor Point (MAP) selection algorithm, handoff time delay, Partner Node (PN)
