基于节点稳定性与跨层优化的MANET路由设计
针对移动自组织网络（MANET）中优化链路状态路由（OLSR）协议路由稳定性差和端到端延时高的问题，提出一种改进的OLSR路由协议。考虑MANET拓扑的移动性，通过优先选择平均相遇率较小、稳定性较高的中继节点构建移动拓扑，避免路由震荡。基于跨层技术，利用链路层共享的链路速率优化路由权值，从而提高路由性能。实验结果表明，与OLSR协议相比，改进协议在MANET网络中具有更好的网络稳定性及更低的端到端延时。...

In view of the mobility characteristic of the MANET topology, nodes with lower average encounter probability and higher technology ,routing weights are optimized using the link experimental results show that the improved protocol has network than the OLSR protocol. the mobile topology is constructed by prioritizing the relay stability to avoid route flapping. Based on the cross-layer rate shared by link layer to improve routing performance. The higher network stability and lower end-to-end delay in MANET SHEN Weiyang1 ,LIU Qiang1 ,OUYANG Feng2 （ 1.
