摘要
为了缩短移动节点的切换延迟时间,提出基于多播树的分层移动IPv6(HMIPv6)快速切换方案。该方案采用快速切换方式建立移动锚点与移动节点之间的多播隧道,移动节点在同一个区域内始终使用相同的多播地址。仿真结果表明,与现有HMIPv6方案相比,该方案的切换时间更短、丢包率更低、性能更好。
This paper proposes a fast handoff scheme for Hierarchical Mobile IPv6（HMIPv6） based on multieast tree in order to shorten the handoff delay time for mobile node. This scheme employs fast handoff to establish the multicast tunnel between the anchor and the mobile node. In the same domain, the mobile node is always identified by one multieast address. Simulation results show that handoff time in the scheme is shorter, the packet loss radio is lower and the performance is better, compared with existing HMIPv6 scheme.
