代理移动IPv6的开销分析与自适应优化

The Cost Analysis of Proxy Mobile IPv6 and Adaptive Optimization

为降低代理移动互联网协议版本6(PMIPv6)中包括绑定更新开销和数据转发开销在内的总开销,首先对PMIPv6与MIPv6的绑定更新开销和数据转发开销进行了理论分析,并对比了2种移动性管理方案的总开销.在此基础上提出一种允许移动节点(MN)动态地根据切换频度和流量强度等参数,选择适宜的移动性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采用某种移动性管理机制更好的资源使用效率.

Aiming at decreasing of binding update cost and data transfer cost of proxy mobile Internet protocol version 6 （PMIPv6） network, the concept of integrated optimization is adopted. Comparing the cost of PMIPv6 with MIPv6, the decision function used to determine when PMIPv6 is adopted preferably is obtained, and the adaptive mobility management scheme is proposed, that allows a mobile node （MN） residing in a PMIPv6 domain to select a suitable mobility management dynamically from PMIPv6 and MIPv6 according to its working parameters. Simulation shows that the proposed scheme will have good utilization of resources.
