摘要
zigBee是一种结构简单、低功耗、低数据速率和可靠性高的双向无线网络通信技术,基于ZigBee实现的无线传感器网络具有成本低、安全性高、时延短、省电、网络容量大、易于实现等特点,具有广阔的应用前景,已成为一项新兴的热点研究领域。文章介绍了Zigbee的协议框架、各层的功能及Zigbee无线网络的组成,阐述了基于Ember公司EM250片上系统的无线传感器网络解决方案,对系统的硬软件组成及设计进行了仔细的说明。
ZigBee is a wireless protocol designed for low power consumption, high reliability, two-way wireless networks. It has been widely used in low data rate industry field due to its low unit cost, high security, and large number of nodes, easy deployment features. This paper introduced ZigBee stack architecture, function of each layer, and composition of ZigBee wireless sensor network. The wireless sensor network solution based on Ember＇s EM250 ZigBee system-on-chip have been given, also the system hardware and software modules and design have been discussed.
