移动IPv6分层管理费用的分析与自适应优化

为综合优化分层域内外以网络传输花费和带宽占用为代表的通信管理费用,论文对实施分层移动IPv6前后的费用变化进行了理论分析,得出了判决是否适宜使用分层移动管理的准则,并在此基础上提出一种允许移动节点动态地根据切换频度和流量强度等参数选择适宜的移动管理机制的自适应优化方案.仿真结果表明该方案能获得比静止使用某种移动管理机制更好的资源使用效率,可望具有较好的实际应用价值.

Analysis of Hierarchical Management Cost of Mobile IPv6 and Adaptive Optimization

As a micro mobility approach,Hierarchical Mobile IPv6 (HMIPv6) has been designed to improve the performance of Mobile IPv6 (MIPv6) on the number of management messages and handoff latency.Aiming at decreasing transfer cost and bandwidth consumption when enhancing the mobility management of Internet,the concept of integrated optimization is adopted in this paper.After theoretical computing and comparing the cost of HMIPv6 with MIPv6's,the judgment rules used to determine when HMIPv6 is adopted preferably are obtained,and Adaptive Mobility Management Scheme (AMMS) is proposed,which allows a mobile node residing in a HMIPv6 domain to select a suitable mobility management dynamically from MIPv6 and HMIPv6 according to its working parameters.The results of simulation show the expected performance.
