摘要
针对移动IP在无线局域网下的应用,提出了一种新的基于链路层的移动IP快速切换方法,通过在无线局域网的无线接入点间加入特定的MAC网桥来减少移动节点在切换时产生的切换时延,进而减少移动节点上行和下行方向上的数据包的丢失,达到对移动IP切换进行优化的目的。此方法在无线局域网实际环境中进行了性能测试,结果证明优化后的时延较之原来普通移动IP切换时延有明显降低。
A new latency handoff method based on the MAC layer was proposed to improve the performance of mobile IP application under wireless LAN environment. A dedicated MAC bridge was used at access points in a wireless LAN to reduce the handoff delay in the method. It can alleviate data packet loss on mobile node up and down without altering the current mobile IP specifications so that it can optimize mobile IP handoff. Its performance was evaluated in an actual network and the effectiveness of our approach was verified.
