摘要
介绍RSVP协议基本原理,提出一种基于移动ip网络环境的动态移动RSVP扩展方案。该方案在蜂窝中通过使用移动代理,利用移动ip网络支持组播和GPS预测节点移动,根据信号传输距离计算出移动节点本地蜂窝链路可用时间,建立当前范围预留和预范围预留两条路径,自动进行数据传输切换。实验结果表明,在移动ip网络使用动态移动RSVP比移动RSVP在数据包的投递率和延迟时间方面表现更好。
RSVP basis principle is introduced, and an extension of RSVP in mobile IP network is proposed dynamic mobile RSVE Under this approach, there are some main extensions： using the concept of mobile proxy in the cell, using multicast by mobile IP network supported, using GPS to predictive the userps next position, computing the mobile node＇ s useful-time in the localization cell link, building up two path： current range reservation and range pre-reservation, and auto data flow switching. Compared with mobile RSVP in the results by simulations demonstrate, we can obtain that dynamic mobile RSVP can not only decrease network overhead and average end-to-end delay, but also the number tree＇ s reconstruct and enhance the pakects deliver ratio.
