摘　　要：无线传感器网络作为下一代的传感器网络,在人们的各个领域和生产活动都有着广阔的应用前景。将轮询服务与无线传感器网络相结合,可以提高系统的资源利用率,能够减少数据业务在进行服务时带来的冲突。介绍了轮询系统的3种服务类型,并对它们进行了性能上的对比。为了能在无线传感器网络中实现不同类型的轮询服务,在设计过程选择TinyOS无线传感网络操作系统作为软件平台,以cc2538cb传感器节点作为硬件平台,在无线传感器网络中构建了一个轮询控制系统。然后通过轮询服务的特性平均排队队长和平均时延,来评判在无线传感器网络中所设计的轮询系统的合理性和有效性。并以设计作为基础,实现混合式、区分优先级的两级轮询服务系统。Wireless sensor network as the next generation of sensor networks,it has a broad application prospects in various fields and production activities.Combining apolling service with a wireless sensor network can improve the resource utilization of the system and reduce the conflict in the service of the data service.This article describes the three types of service for the polling system and compares them with performance.In order to achieve different types of polling services in wireless sensor networks,we choose TinyOS wireless sensor network operating system as software platform,cc2538 cb sensor node as hardware platform,and construct a polling control in wireless sensor network system.Then,the rationality and validity of the polling system designed in the wireless sensor network are evaluated by the average queuing length and average delay of the polling service.At the same time,the future work is prospected,and the design of this article as a basis to achieve a hybrid,prioritized two-level polling service system.
