摘　　要： 基于服务区分,对中高速传感器网络的QoS路由算法问题进行建模和分析。提出基于蚁群优化的路由算法以保证不同的服务有不同的QoS参数,通过设置反向抑制机制来保证不同服务的优先级别。仿真表明,基于蚁群算法与区分服务的路由协议更适合中高速传感器网络对不同业务的QoS需求,而反向抑制保证了高级别服务的优先级。 This article focuses on the issue of QoS routing algorithm for medium and high rate wireless sensor networks （MHR-WSN）. The algorithm is analysed based on differentiated services and coresponding model is set up as well. A QoS routing algorithm based on ant colony is presented to guarantee different service will have different QoS parameters in MHS-WSN. Reverse inhibition mechanism is set up to ensure the priority of different services. Simulation results show that the routing protocol based on ant colony algorithm and differentiated services is more suitable to MHS-WSN, in which different service has its own QoS requirement, whereas the priority of higher service is guaranteed by the reverse inhibition.
