The Design and Realization of Embedded Gateway Based on WSN

The gateway realizes the fusion of wireless sensor network and external network. Some low performance gateways cannot meet the requirement of surge data collection. Consequently, a gateway that based on PXA270, using embedded Linux is designed to meet the requirement. To protect the data that transmitted by Ethernet through the gateway, a TCP/IP strategy is constituted, which can reduce the probability of data missing. To realize the communication of WSN and external network, the application layer program is designed. It can collect, process, transmit the data of WSN, and supply multi-clients services including data display or download concurrently. The client can visit the gateway via Website or command console.
