Abstract:

When handover bursts out, the generation of Care-of Address(CoA) of mobile routers, especially nested ones, and the duplicate address detection followed are the most time-consuming parts compared with the other processes. In this paper, after reviewing the existing schemes in the eye of delay related to CoA, it is based on access router tree model and Hash function, gives a novel scheme of CoA configuration and corresponding handover algorithm, to reduce the time cost and the signal overhead. Performance evaluation indicates that, compared with the existing solutions, lower delay can be achieved in CoA configuration of nested mobile routers and also in handover.

Key words: mobile router, Care-of Address(CoA), tree model, nest, handover

摘要：

嵌套移动路由器的转交地址配置及随后的重复地址检查对网络移动的时间开销较大。为此，在分析现有移动路由器的转交地址配置方案基础上，提出一种基于接入路由器树模型和Hash函数的嵌套移动路由器转交地址配置方法及其相应的切换算法，以减小时间开销和控制信令开销。仿真结果表明，与现有方案相比，该方法能够降低嵌套移动路由器的转交地址配置及相应切换的延时。
