摘要
PMIPv6在建立双向隧道传输数据时会导致传输路径非最优,同时,已有的路由优化策略信令负载过大且滞后于绑定更新过程。针对该问题,提出一种与绑定更新同步进行的基于ROE的轻量型路由优化策略,引入流体移动模型分析。实验结果表明,采用新策略后,网络报文开销减小,路由优化效率高,特别适合于移动节点低速运动的情况。
Establishing bi-directional tunnel for data transmission leads to the transmission path is non-optimal in Proxy Mobile IPv6, and in the existing strategy route optimization lagged behind the procedure of binding update with the fault of large signaling load. Aiming at these problems, this paper presents a ROE-based light weight route optimization strategy, which is in parallel with the binding update. Experimental result using fluid-flow mobility model indicates that the packet overhead is small and route optimization efficiency is high, especially suitable for low-speed movement of Mobile Node（MN）.
