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(wǎng)環(huán)境中,單向鏈路的普遍存在,分析了它的產(chǎn)生原因、它對目前協(xié)議棧的影響;然后,我們給出了一種按需路由的自組網(wǎng)單向鏈路路由算法,它只有在需要路徑的時候才維護路由,使用二循環(huán)路由尋徑算法以建立節(jié)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(jié)點向上游節(jié)點傳遞信息。
