> 中文摘要: 针对移动支持协议的移动管理代价进行了研究,提出了一种合适的网络模型.在此网络模型的基础上,采用理论分析的方法分析了使用各移动支持协议时,为支持MH(mobile host)移动给网络带来的信令开销,并采用数值仿真的方法,对只使用移动IP协议和引入层次移动时的信令开销以及采用MIP-RR,CIP和HAWAII等不同微移动协议时的信令开销进行了比较.结果表明:引入层次移动与只使用移动IP相比,显著减少了网络的信令开销;在不同的微移动协议中,使用显式删除旧路径的路径维护策略与频繁发送周期性的刷新报文相比,给网络带来的信令开销较小;使用路径更新报文发送到交叉MRA(mobile routing Agent)的路径更新方法与路径更新报文发送到GW(gateway)相比,具有较小的网络信令开销.
Abstract:The mobility management cost of mobility support protocols is studied. Firstly a suitable network model is proposed and the signaling overhead brought to network in order to support MHs’ (mobile host) mobility using various mobility support protocols is analyzed theoretically. On this base, a numerical simulation method is applied to compare the signaling overhead when only using mobile IP with introducing hierarchical mobility and when applying different micro-mobility protocols such as MIP-RR, CIP and HAWAII. The results show that introducing hierarchical mobility decreases the network signaling overhead observably comparing with only using mobile IP. In different micro-mobility protocols, the route maintenance strategy of deleting old routes explicitly brings less signaling overhead than frequently sending refresh messages periodically, and the route update method of sending route update messages to crossover MRA (mobile routing Agent) brings less signaling overhead than sending messages to GW (gateway).
