Design and Implementation of Embedded Wireless Gateway

This paper analyses the wireless sensor grid architecture which can´t meet the current requirements that the monitoring systems need to be easily deployed and maintained, to keep high stability and strong reliability in the dangerous environment, such as tunnel and caverns. Directed at these problems, an optimized grid architecture was developed. The paper introduces the advantages of the new architecture, and discusses the security strategies of the architecture from data collecting and forwarding, provides the designing schemes of the key node which is embedded in the wireless gateway both in hardware and software. The architecture with high security, flexible structure and strong scalaility characteristics can be applied widely in other security monitoring and control fields.
