Design and Realization of Wireless Sensor Network Gateway Based on ZigBee and GPRS

This paper discusses an embedded access platform, which takes S3C2410 as the center core and is built upon the Linux operating system. Based on the character and advantage of ZigBee and GPRS, this article advances the solution scheme of the wireless sensor network gateway. Mainly analyzes the software design of the gateway, including the way to realize the connection of ZigBee protocol and GPRS network, along with the design of data conversion task between ZigBee network and GPRS network. And it proposed a solution of data loss, which is caused by the different transmitting rates of ZigBee module and GPRS module. This paper also describes the structure of hardware platform and running process, and analyzes the structure of the three layers software system, as well as PPP protocolpsilas characteristics and transplanting key point. As a result, the wireless data communication link between the embedded gateway and GPRS network is set up, and the solution of keeping the gateway on line is proposed.
