| 摘 要： | 基于指针推进机制的分层移动IPv6方案因未考虑移动锚点管理域的影响,导致较高的注册和报文分发开销.提出一种面向分层移动IPv6网络的动态指针推进机制(dynamic pointer forwarding scheme for HMIPv6 networks,简称DPF-HMIPv6),移动节点可根据所选移动锚点的管理域大小,动态调整指针推进机制.若所选移动锚点的管理域大于特定阈值,则移动节点通过在接入路由器间构建指针链来避免频繁地向移动锚点注册;若所选移动锚点的管理域小于阈值,则移动节点通过在移动锚点间构建指针链来避免频繁地向家乡代理注册.数值分析和仿真实验的结果表明,该方案能够有效解决现有方案存在的问题,显著降低分层移动IPv6网络的开销.

| Abstract: | The recent pointer forwarding schemes for HMIPv6,without consideration of MAP's(mobile anchor point) coverage,may lead to high registration and packet delivery costs.A dynamic pointer forwarding scheme for HMIPv6 networks(DPF-HMIPv6) is proposed in this paper.The scheme allows mobile nodes to execute pointer forwarding schemes,dynamically,in accordance with MAP's coverage.The pointer forwarding scheme,based on the access router,is used on the condition that mobile node chooses an MAP with a coverage larger ... |
