We discuss the formation of the unidirectional links and their influence on the manet routing protocols such as dsr , dsdv , aodv . solutions are given to overcom e the problems , we analyze some of they and point out their limitations . in the third part , we show a new on - demand routing strategy supported unidirectional links , it use the two circuits route search algorithms to establish the route from the source node to the destination and backward with directions ; it transfer the route error messages from the backward positions to the forward positions one by one ; it apply the packet encapsulation technique to forward the packets through the unidirectional links and introduced the circuit path to transmit information from the forward node to the backward node 接着，指出在移动自组网环境中，单向链路的普遍存在，分析了它的产生原因、它对目前协议栈的影响；然后，我们给出了一种按需路由的自组网单向链路路由算法，它只有在需要路径的时候才维护路由，使用二循环路由寻径算法以建立节点间的路径，使用逐跳逆向传递的方式报告路由终断，使用封装广播的方式沿单向链路正向传输，使用报文封装方式支持单向链路下游节点向上游节点传递信息。
