| 摘 要： | 无线传感器网络节点能量受限，在设计过程中必须优先考虑能耗问题。通过低功耗硬件选型，设计一款基于16位超低功耗处理器MSP430F5438A及IEEE802.15.4射频收发器AT86RF231的无线传感器网络节点。软件设计方面，使用Contiki操作系统，使节点系统平台摆脱了前后台或有限状态机的软件设计思想，可以使用模块化、进程化风格对节点进行编程。设计测试平台，进行多点环境信息采集实验并对节点功耗进行实际测试，验证节点的实用性及低功耗特性。

| Abstract: | Power efficiency should be the primary concern when designing wireless sensor network because nodes are energy constrained. Through low power hardware selection, a WSN node was proposed based on ultra-low power MCU MSP430F5438A and IEEE 802.15.4 transceiver AT86RF231. The use of Contiki OS eliminated foreground/background software design pattern or finite state machine, and developers could use modularized and thread-like code style in software designing. Test platform was built to perform multi-point information gathering experiment and static power measurement. These tests show practical use and low-power feature of the node. |
