无线移动网关配置协议研究

摘要

As one of the development trend of next generation Internet,it is necessary for mobile Internet to support not only the mobile gateways but also the small or medium scale mobile networks.Therefore,the efficient configuration and service policy have become the key technologies of mobile gateways.A hierarchical configuration protocol based on the thought of MANET (Mobile Ad-hoc Network) is proposed to split the mobile gateways into clusters and integrate the clusters into Later-net by the connection of cluster heads and mobile gateways.Furthermore, three kinds of service strategies are proposed and analyzed through the simulation experiments.The experimental results indicate that the performance of the proposed protocol and service strategies can satisfy the requirements of mobile networks efficiently.%向移动领域扩展是下一代互联网的主要发展方向,移动互联网不仅能支持单个移动终端,而且需要支持中小规模的移动子网,其中移动网关的配置及服务策略是关键技术之一.为此提出了一个层次化的配置协议,利用移动自组网(MANET)分簇管理的思想,将移动终端进行适当分簇并选举簇首管理内部节点,集成移动网关将不同移动簇群的无线网络进行连接.在此基础上提出了三种移动网关的服务策略,对该配置协议进行了仿真试验,分析比较了在不同服务策略下移动网关的关键性能指标,验证了该协议能够较好地满足移动网络的需求.
