Abstract: This paper proposes the design principle of sink node of the Wireless Sensor Network(WSN), analyzes the characteristic and requirement of the sink node, and makes the choice of devices. Based on the low power consuming PXA270 embedded processor, a hardware platform of sink node is implemented with serial port, Ethernet, USB host and CF card interface. The boot process of boot loader is analyzed elaborately, and the porting of Blob in the hardware platform is implemented.

Key words: Wireless Sensor Network(WSN), sink node, boot loader
