互联网工程任务组(IETF)所提出的分层移动IPv6(HMIPv6),通过引入移动锚点(MAP)降低移动IPv6网络绑定更新所产生的信令开销,但HMIPv6未给出如何配置MAP及MAP域的具体方法.基于节点的移动跳数,提出一种动态选择MAP及配置MAP域的具体方法,以实现HMIPv6.在此基础上引入寻呼策略及其优化模型,对寻呼区域进行优化设计,提出了引入寻呼降低信令开销的一个条件.数值分析表明,通过设置适当的跳数阈值,可降低HMIPv6的信令开销.
Hierarchical Mobile IPv6 (HMIPv6) proposed by the Internet Engineering Task Force (IETF) reduces signaling overhead caused by binding update of mobile IPv6 networks by introducing a mobile anchor (MAP), but HMIPv6 does not give any guidance on how to configure MAPs and MAPs Based on the number of mobile hops, this paper proposes a specific method to dynamically select the MAP and configure the MAP domain to implement the HMIPv6. Based on this, a paging strategy and its optimization model are introduced to optimize the paging area , A condition of introducing paging to reduce signaling overhead is proposed.Numerical analysis shows that signaling overhead of HMIPv6 can be reduced by setting proper hop threshold.
