ZigBee自组网的网间串扰和通信解决方案

A Solution of Inter-network Crosstalk and Communication in ZigBee Ad Hoc Networks

当同一个区域存在多个ZigBee无线传感网络时,为了解决这些子网间传递信息相互干扰、协调器建网参数异常以及节点入网无序等网间串扰问题,文章探索出一种ZigBee子网间规范通信的方法。以CC2530为硬件平台,采用Z-Stack协议栈作为实现ZigBee技术的软件平台,通过对Z-Stack协议栈中节点类型、个域网标识符、信道切换以及网络状态存储等多项技术的研究改进,并在不同类型的节点上烧录与其匹配的Z-Stack协议栈,解决了网间串扰和网间通信问题。在实践测试中采用若干CC2530节点组成多个ZigBee子网,验证了方案的可行性。

When there are multiple ZigBee wireless sensor networks in the same area, in order to solve the inter-networkcrosstalk problem such as mutual interference of the information transmission among sub-networks, the anomaly of coordinatornetwork construction parameters and nodes disorderly joining in the network, we propose a ZigBee inter-network standard com-munication method. Using CC2530 as the hardware platform, the Z-Stack protocol stack is applied as the software platform torealize ZigBee technology. Through the research on the node type, network PANID, channel switching and network state stor-age in the Z-Stack protocol stack, and burning the matched Z-Stack protocol stack on different types of nodes, we can solve theinter-network crosstalk and inter-network communication problems. Several CC2530 nodes are used to compose multiple Zig-Bee subnets in practice test, which verifies the feasibility of the proposed scheme.
