无线电工程

ZigBee是基于IEEE802.15.4的一种新兴的无线网络技术。详细介绍了ZigBee协议栈的架构、层协议的参考模型。分析了ZigBee协议网络层关键技术,提出了具体网络层实现方案,并给出了基于该技术的路由过程。在以TI公司的CC2430芯片搭建的硬件平台上,测试了基于ZigBee协议的路由实现。实验表明,基于ZigBee协议组建的无线网络,能够实现较复杂网络的路由功能,网络的可扩展性强,具有很好的实用效果。

The paper describes the architecture of ZigBee protocol stack and reference model of layer protocol in detail,introduces the key technologies of network layer of ZigBee protocol stack,and presents the implementation scheme of network layer.By using the hardware platform built by CC2430 CMOS chip,the establishment of routing process based on ZigBee has been tested.The experiment indicates the wireless network based on ZigBee protocol can implement the routing function of complex network,and has the strong expansibility and good practicality.
