Design of a General Wireless Sensor Node Based on TinyOS

无线传感器网络是物联网感知层的重要组成部分,为方便将无线传感器网络快速应用于多个领域,开发了一种基于TinyOS操作系统的通用无线传感器网络节点。利用ATmega128单片机作为节点的微控制器,采用CC1000射频芯片作为系统的无线收发器件,详细介绍了系统的软硬件设计。从数据传输可靠性测试、通信距离测试和功耗测试这三个方面对所设计的无线传感器节点的性能进行了验证。相关实验结果为该传感器节点在多种领域的应用提供了参考和依据。

Wireless sensor network is an important part of the perception layer of the Internet of things. In order to facilitate the rapid application of wireless sensor network in more fields,a general wireless sensor network node based on TinyOS operating system is developed. The ATmega128 MCU is used as the micro controller of the node,and the CC1000 RF chip is used as the wireless transceiver. Both the hardware and software design of the system is introduced in details. The performances of the designed wireless sensor node is tested from three aspects: data transmission reliability,communication distance and power consumption. The experimental results provide reference and basis for the future application of the sensor node in various fields.
