为合理使用有限的无线传感器网络(wirless sensor network,WSN)能量资源,为用户提供有保证的网络服务应用,采用通过节点调度来合理组织网络中节点的工作状态,并且按照满足一定实时性的可靠性路由算法传输数据的方式,提出了一种面向服务质量的WSN节能调度算法,算法分为节点状态调度和基于服务质量(quality of service,Qo S)的路由协议两部分,并且对其进行仿真。仿真结果证明,算法在数据传输的实时性和可靠性方面性能优越,可扩展性好,并且节约了能量,延长了网络生存周期。

To rationally use limited wireless sensor network（WSN） energy resources and to provide users with guaranteed network service the reasonable organization node is used for scheduling network nodes in working condition. And according to the way of data transmission by real-time routing algorithm, proposes a WSN energy-efficient scheduling algorithm for quality of service. Algorithms are divided into state of node scheduling and routing protocol based on the quality of service （QoS）. And the simulation is carried out. The results show that the algorithm in the real-time and reliability of data transmission performance is superior. It has good scalability, and saves energy,prolongs the network life cycle.
