Wireless sensor network communication terminal based on embedded Linux and Xbee

In this paper, raspberry Pi is used as an embedded Linux board which is used as a communication terminal in wireless sensor network. Raspberry pi uses ARM 11 system structure of the microcontroller in which Linux operating system can install in it. The embedded Linux board connects the entire sensor node via zigbee protocol in the wireless sensor network and collects sensors data from the sensors. This board continuously collects all the real time data from different sensor nodes a save in the raspberry pi board which can be accessed remotely on more than one client's computer. Thus we design the application which can group a large number of data based on the embedded Linux system platform. It could reduce the power consumption of the wireless sensor node; meanwhile, it improves the quantities of data processing ability and strengthens the data transmission speed.
