中文摘要：

本文详细介绍了一种无线传感器网络（WSN）硬件平台OpenWSN的设计与实现。该方案采用ARM系列处理器,符合802.15.4标准的无线收发芯片,三维振动和温度等传感器。其尺寸略大于Telos,但处理能力高于目前广泛使用的Gains,Mica,Telos等研究性硬件平台。OpenWSN能够承担图像采集与传输、汇聚节点等对性能要求更高的应用,可与目前基于MCU方式的结点形成良好的互补。本设计遵循了节点的标准化、微型化,低功耗和扩展性等原则。对该节点的测试表明,该方案较好地实现了上述目标,因此它可以成为研究人员选用无线传感器网络平台的理想高端选择。

英文摘要：

This paper proposes and implements a new open research platform of Wireless sensor networks （WSN） named OpenWSN. The scheme utilizes microcontroller of ARM family, wireless RF transceiver accorded with 802. 15. 4 specification, three dimension vibration sensor, temperature sensor and etc. Larger sized than Telos, OpenWSN has higher processing capability than current pervasive research hardware like Gains, Mica and Telos. OpenWSN can bear higher performance application, such as image data collection and pan coordinator, thus preferably complement current MCU scheme. OpenWSN follows the principle of standardization, miniature low energy consumption and expansibility. Test of the node shows that the implementation achieves the goal preferabiy and is an ideal choice of wireless sensor network platform for researchers.
