摘　　要：设计了一种支持单向链路并能保证实时业务服务质量的路由协议QUR(QoS-supportUnidirectional-linkRout-ing),提出了一种新的带宽计算方法。QUR在路由选择时综合考虑路径的带宽因素和跳数因素,并为实时业务预约资源,提高了网络的整体效率。仿真结果表明:QUR协议保证了实时业务的服务质量,在网络吞吐量和相对控制开销方面优于DSDV协议。A new routing protocol called QUR（QoS-support Unidirectional-link Routing） is designed to provide QoS support in MANETs with unidirectional links,and a new bandwidth calculation algorithm is proposed.Both the hop distance and the bandwidth of the path are considered in QUR to improve the performance of MANETs,and bandwidth resource is reserved along the path for real-time traffic.The simulation results show that the QoS of real-time traffic is guaranteed in QUR,and QUR achieves better performance in terms of throughput and control overhead compared with DSDV.
