【摘要】 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。更多还原

【Abstract】 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.更多还原
