摘要
当移动节点发生切换时,其切换时延和丢包率问题将严重影响实时业务的应用。针对这一问题,该文进行了理论分析并提出了一种基于地址池的层次型移动IPv6切换算法(APHMIPv6)。该算法与层次型模型相结合,采用基于地址池的有状态地址配置策略以及域间切换时利用隧道机制来提高切换性能。仿真结果表明,该算法能有效地减少移动节点切换时延和丢包率,尤其在域间切换时,性能更加显著。
When a mobile node goes into a new subnet, latency and packet loss of handover will affect theapplication of real-time service. The paper proposes an enhanced handover algorithm, address-pool based HMIPv6 (APHMIPv6), which combines with the hierarchical model, and adopts address-pool based stateful address configuration policy and tunnel mechanism during inter-domain handover. The simulation shows that the APHMIPv6 algorithm decreases the handover latency and packets loss effectively, especially in case of inter-domain handover.
