Abstract: This stable link QoS routing protocol SQAODV is proposed based on AODV.It can satisfy the band width constraint，estimate the stable parameter by the received packet power，and choose the most stable and QoS path from several paths in the destination node in the routing detected process.Simulation results show that the performance of SQAODV is better than AODV in packed delivery ratio，average peer-to-peer delay and routing cost.

摘要： 在AODV的基础上提出了一种基于链路稳定度的QoS路由协议SQAODV。该协议通过带宽约束和链路稳定度的估计，在路径发现过程中，从到达目的节点的多条路径中选择一条最稳定且满足QoS需求的路径返回源节点提供QoS保证。仿真的实验结果表明，改进后的SQAODV协议，在分组到达率和数据平均传输延时方面的性能都有改善。
