| 摘 要： | 针对阿ad hoc网络中节点能源受限，隐藏终端和QoS需求等问题，提出了一种基于能源节省的单向QoS路由协议。该协议利用网络中存在的单向链路，采用QoS策略，通过在最短路由集中选取能源较多的路径承担较多传输任务以延长网络生存时间。仿真结果表明，该协议比相关路由算法具有更好的网络性能，能有效支持单向ad hoc网络中具有QoS需求的信息传输。

| Abstract: | A unidirectional QoS routing protocol based on energy conserving is proposed on the ground that each node in ad hoc network possesses some problems, such as energy conserving, hidden terminal, QoS requirements, and so on. In order to maximize the network lifetime, this protocol takes full advantage of unidirectional links, adopts QoS policy, and selects the optimal flow paths by assigning traffic between more proportion to routes’ energy reserves and shorter routes. Simulation results show that this protocol is superior network performance than other protocols, and efficient supports information transmitting with QoS requirements in ad hoc network with unidirectional link. |

| Keywords: | Ad hoc network Energy conserving Unidirectional links QoS routing |
