| 摘 要： | 无线局域网采用移动IP实现移动性管理.移动IP切换存在切换时延大,数据包易丢失的问题.切换时延由移动检测时延和注册时延组成,而移动检测时延在其中占主要部分.文章提出了一种移动检测优化方案,采用了自适应绑定的算法,同时充分考虑了域内小范围高频度切换的情况,使移动节点在无线局域网环境中进行快速有效的切换.

| Abstract: | Mobile IP is a promising solution for mobility management in the wireless network. There are large handoff latency and the packet being easier to lose on mobile IP handoff. The handoff latency is composed of movement detection latency and register latency, and the former one is the main section of it. This article proposes a optimization mechanism of movement detection, which adopt an adaptive-binding algorithm. Meanwhile, the special situation of frequent handoffs in small region is also fully considered. This scheme implements fast and stable handoff in Wireless LANs for mobile nodes. |
