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
接著，指出在移動自組網環境中，單向鏈路的普遍存在，分析了它的產生原因、它對目前協議棧的影響；然後，我們給出了一種按需路由的自組網單向鏈路路由演算法，它只有在需要路徑的時候才維護路由，使用二循環路由尋徑演算法以建立節點間的路徑，使用逐跳逆向傳遞的方式報告路由終斷，使用封裝廣播的方式沿單向鏈路正向傳輸，使用報文封裝方式支持單向鏈路下游節點向上游節點傳遞信息。 -
