环境监测无线传感器网络节点的设计 针对环境监测的要求,开发了一种兼容型的无线传感器网络节点系统。该系统以MSP430FG4618为核心,采用 CC2420 214G射频芯片,软件上移植了德州仪器( TI) ZigBee协议栈,并在应用层开发了通信程序。该系统可以组建成稳定的网状网络,功耗低,数据传输稳定.-Environmental monitoring wireless sensor network node designed for environmental monitoring requirements, to develop a compatible system for wireless sensor network node. The system MSP430FG4618 as the core, using radio frequency chip CC2420 214G, software transplanted Texas Instruments (TI) ZigBee protocol stack, and the application layer has developed a communication program. The system can be formed into a stable mesh networking, low power consumption, data transmission and stability.
