无线传感网络(WSN)目前在工业领域得到了越来越广泛的应用,主流的WSN协议包括ZigBee、WIA-PA和Wireless HART.这三种无线短程通信协议在物理层上均兼容IEEE 802.15.4物理层(PHY)协议规范,但在媒介访问控制(MAC)及以上各层则完全不同.通过对这三种WSN协议的MAC层进行分析和对比,以及对MAC网络性能的模拟分析计算,给出了三种WSN的适用条件.%The wireless sensor network (WSN) has been more widely used in industrial fields, the mainstream WSN protocols include ZigBee, WIA-PA and Wireless HART. These three of the wireless short-range communication protocols are all compatible with IEEE 802. 15. 4-PHY protocol specification on the physical layer, but they are totally different on the media access control ( MAC) layer and the upper layers. These three WSN protocols are analyzed and compared on the MAC layer, and the network performance of MAC is simulated, analyzed and calculated, and the applicable conditions of these three WSNs are given.
