动态环境下嵌套移动网络的快速路由优化

摘要

Aiming at the long convergence time during route optimization after the continual handoff and sub-optimal route problem of the communication in intra-NEMO, an optimization scheme using tree information option is proposed in dynamic environment of nested mobile network. The scheme uses the tree information option to extend route advertisement message and bring the local binding updating mechanism into the mobile network, which reduces the recovering time of communication disturbed by continual handoff, and guarantees the routing optimization after traffics increasing between nodes in intra-NEMO.%针对嵌套移动网络在快速移动场景下,频繁切换带来的较长通信恢复收敛时间和网络内部节点通信的次路由优化问题,提出了一种使用树信息选项的快速路由优化方案.该方案通过使用树信息选项对RA消息进行扩展和新增本地绑定(LBU)机制,减少了在快速变化环境中由于切换造成的通信中断时间,并且能在移动网络内部节点交互业务增多时,保证路由的优化.
