摘要
代理移动IPv6移动节点发生域内切换时,存在着重建路由优化路径时延长、切换开销大的问题,为此,提出一种改进的代理移动IPv6域内路由优化方案。在移动节点即将发生域内切换时,由新接入的移动网关发起切换,减少了切换过程中本地移动锚点的参与,在移动节点接入新网络之前完成优化路径的建立。仿真实验结果表明,新方案在切换时延和切换开销方面的性能优于原有的代理移动IPv6域内路由优化方案。
Proxy mobile IPv6 mobile node＇s intra-domain handover will lead to the long delay and the large handover cost when route optimization path is re-established,therefore,an improved proxy mobile IPv6 intra-domain route optimization approach is proposed.In the new approach,new mobile access gateway initiates the handover when mobile node impending had an intra-domain handover,this process reduces the participation of local mobility anchor and achieves the establishment of optimization path before mobile node accesses in the new network.The simulation results demonstrate that new approach is better than the original Proxy Mobile IPv6 intra-domain route optimization approach in terms of handover delay and handover cost.
