摘要
对移动协议网络层切换时延进行了研究。提出合适的网络模型,从理论上分析了各移动协议的路径更新时间,并采用数值仿真的方法对采用微观移动协议和只使用移动IP协议以及采用不同的微观移动协议的情形进行了比较。研究结果表明路径更新时间与所采用的移动协议的路径更新方法相关;采用微观移动协议时的路径更新时间远小于只使用移动IP协议时的情形;在所有的微观移动协议中,MIP-RR协议中使用的路径更新方法性能最佳。
Network layer handoff delay of mobility protocols was studied. Firstly a suitable network model was proposed and the route update time of various mobility protocols was analyzed theoretically. In this base the numerical simulation method was applied to compare the performance between mobile IP and micro-mobility protocol and among different micro-mobility protocols. The results show that the route update time is related with the route update methods of mobility protocols. The route update time of micro-mobility protocol is shorter than mobile IP. In all micro-mobility protocols, the route update method of MIP-RR protocol has the optimal performance.
