基于PXA270的无线传感器网络汇聚节点设计与实现

Design and implementation of wireless sensor network sink node based on PXA270

研究了无线传感器网络中汇聚节点的设计原则,在分析PXA270处理器特点的基础上设计并实现了一个汇聚节点硬件。基于此,进一步对在一个新的硬件平台上实现引导加载程序和移植U-boot作了深入探讨,并最终实现了汇聚节点的软硬件平台。

This paper proposed the design principle of sink node of the wirless sensor network, based on the analysis of the character of the processor PXA270,designed a sinknode hardware. Then,discussed the implementation of the bootloader on a new hardware platform and gave the process of the U-boot transplants At last, implemented, sinknode software and hardware platform.
