摘　　要：设计了一种低功耗无线传感器网络节点,并完成了TinyOS操作系统在该节点中的移植。该节点的硬件设计综合考虑了功耗和性能等诸多方面,与其他无线传感器网络节点平台相比功耗低、通信距离远。此外,为新的MSP430系列处理器改进了TinyOS的设计工具链环境,使得软件编写可以不局限于GCC编译器。将TinyOS操作系统移植到新节点上,实现了射频收发器CC2520的射频协议栈。A novel low-power wireless sensor network node is designed and TinyOS is transplanted in the node. Power consumption and performance are considered for hardware design of the sensor node. The node has lower power consumption and further communication than other network node platform. By improving the design implement chain environment of TinyOS for the new MSP430 series processor, the software programming can not be restricted to GCC translator-editor. Furthermore, the RF protocol stack of RF transceiver CC2520 is realized and TinyOS is transplanted to the node.
