摘　　要：为了最大限度的提高无线传感器网络资源的利用率,突破传统轮询系统研究不能应用于真实无线传感器网络的限制,将轮询控制的门限服务方式接入无线传感器网络。本文简要介绍了无线传感器网络的结构,分析了轮询系统中的门限服务方式。以cc2530节点作为硬件平台,利用分簇的方式形成了适合门限服务控制的网络,基于ZStack进行了软件的设计,在无线传感器网络中实现了门限服务控制。最后统计计算了门限服务系统的平均时延、平均排队队长两个指标,以此来评估系统的正确性,结果表明,系统能够正确运行,性能指标和理论值一致。In order to maximize the utilization of wireless sensor network resources, the threshold service mode of polling control is connected to the wireless sensor network. This paper briefly introduces the structure of the wireless sensor network and analyzes the threshold service mode in the polling system. The cc2530 node is used as the hardware platform to form a network suitable for threshold service control by clustering. The software design is based on ZStack, and the threshold service control is implemented in the wireless sensor network. Finally, the average delay and average queue length of the threshold service system are calculated to evaluate the correctness of the system. The results show that the system can operate correctly and the performance index is consistent with the theoretical value.
