| 摘 要： | 切换是移动支持协议研究的重要内容,其性能好坏对移动网络的性能和服务质量提供具有至关重要的影响.在合适的网络模型和切换模型的基础上,通过理论分析和数值仿真的方法对各类移动支持协议(包括移动IP与微观移动协议以及不同的微观移动协议)的切换性能进行了深入的研究和比较.结果表明,切换性能受无线网络参数和移动支持协议的路径更新算法两个因素影响;采用微观移动协议时的切换性能好于只使用移动IP时的情形;在所有微观移动协议中,MIP-RR和MMP协议中的路径更新算法切换性能最佳.

| Abstract: | Handoff is an important research topic of mobility support protocols. It has great effects on the performance and quality-of-service of mobile networks. Based on appropriate network model and handoff model, the handoff performance of various mobility support protocols is deeply studied and compared through theoretical analysis and numerical simulation. The comparisons are made between mobile IP and micro-mobility protocol, and between different micro-mobility protocols. The results show that wireless network parameters and route update algorithms of mobility support protocols affect the handoff performance. The handoff performance when applying micro-mobility protocols is better than when only using Mobile IP. In all micro-mobility protocols, the route update algorithm of MIP-RR and MMP has the optimal performance. |
