摘　　要：提出了基于AODV(Adhocondemanddistancevector)路由协议的自愈模型(SHAODV),旨在提高对节点移动和通信中断的抵抗力.利用路由接纳控制(CAC)来保障建立长寿命路由;通过监测接收信噪比来判断链路的稳定程度,在链路断开之前将不稳定路由本地自愈;路由优化方案能将修复后的路由优化.仿真结果表明,该协议模型具有低路由开销和抗中断性等优点.A self-healing routing protocol based on Ad hoc on demand distance vector (SHAODV) is proposed to against node moving and communication breaking. In SHAODV, the connection admission control assures constructed route of long life. The link stability model can detect the stability of link for self-healing of unstable route locally. The self-healed route can be optimized well by the optimization scheme. Simulation result shows that this model has low routing overhead and anti-breaking capability.
