摘　　要：针对Ad_Hoc移动网络的特点,提出了一种支持单向Ad_Hoc移动网络,并且具有QoS控制的路由协议QRUA,该协议充分考虑了网络存在的单向链路,利用邻接主机之间的上游主机表UT来选择满足延时和带宽要求的路由,从而可以适应特定环境下单向Ad_Hoc移动网络的QoS应用需求。模拟仿真说明,QRUA协议不但支持单向链路,同时在路由负载以及包传输率等方面具有一定的优势。Aquality of service （QoS） routing based on unidirectional Ad-hoc （QRUA） protocol which can support QoS controlled routing is given to satisfy the demands of Ad-hoc networks with unidirectional links. Through using upper table （UT） between adjoining hosts to choose the route with the limitation of bandwidth and delays, the QRUA can perform well in the scenarios of Ad-hoc networks with unidirectional links. The simulated performance of the QRUA is done and reported. The result shows that QRUA can not only work well in the environment of Ad-hoc networks with unidirectional links, but also has some advantages both in deceasing the network overhead and increasing the efficiency of packet transmissions.
