摘要
为了验证ZigBee协议的有效性,叙述了新型无线ZigBee通信技术,介绍ZigBee协议的结构和特点,基于ZigBee协议的无线网络设备以及网络拓扑结构;ZigBee标准协议栈结构及数据在协议栈内部的传输机制。以两个网络设备成网为例,详细给出了ZigBee设备形成网络时,各个设备的工作状态、设备之间网络连接过程以及数据帧的发送过程。最后,通过Microchip公司的ZigBee实验平台验证了ZigBee无线星型组网,实验证明,ZigBee技术是有效的无线传感器网络组网技术。
In order to confirm the effectiveness of ZigBee protocol,the novel ZigBee communication technology,characteristics of ZigBee protocol,ZigBee-based devices in wireless network and network topology are presented,and the structure of ZigBee protocol stack and the mechanism for data transmission are discussed.Different working states of terminals and coordinators,course of linking between terminals and coordinators,and transmission duration of data frames while the wireless network is formatting,are researched.The wireless star network formation was demonstrated by an experiment.The outcome proves that ZigBee is an effective communication technology for wireless network.
