摘　　要：移动自组织网络环境中,选择稳定路由可以提高数据传输率并能有效降低控制信息减少网络拥塞。根据无线自组网的特点,提出了一种新颖的基于信号强度评价链路稳定性的方法,并且基于此方法构建组播路由协议。协议中节点能够根据信号强度预估链路稳定性,选择稳定路由,及时发现修复即将断开的链路。仿真结果表明,协议可以明显提高数据传输率,并且控制开销较低。Stable data delivery structure contributes high data delivery ratio and low control overhead in Mobile Ad hoc Networks（MANETs）.Aecording to the characteristics of MANETs,this paper proposes a novel strategy based on signal strength to quantify link stability, and proposes a multicast protocol based on this strategy.In this protocol, each node calculates link stability based on signal strength,selects stable route,and can repair the link which will break in a short time.Simulation results show that it has higher data delivery ratio and low control overhead.
