摘要
移动IPv6标准比移动IPv4在移动性、安全性、扩展性和路由效率等很多方面有了明显改进,成为解决移动IP潜在的最优方案之一。而切换是移动IPv6的关键技术之一,透明、平滑、快速的网络切换是保证移动节点在移动过程中保持不间断网络连接的基础。该文基于Linux系统建立了移动IPv6实验床,对其MAC层、IP层切换做了一系列实验研究。根据对比实验研究,得出无线网络ESSID和频道等因素对切换性能的影响。通过对实验数据的统计分析,得到各主要切换步骤的时延分布,提出了改进切换性能的几种方法。
A mobile IPv6 testbed based on Linux is set up and a series of experimental studies on the MAC and IP layer handoff are performed. According to the experimental result with statistic analysis, the distribution of mobile IPv6 latency is presented. Factors which affect the handoff efficiency are investigated such as the ESSID and channel of wireless network. Approaches to improving the handoff efficiency are proposed.
