The Design And Its Implementation Of Wireless Sensor Network Gateway
无线传感器网络嵌入式网关的设计与实现

An embedded gateway of wireless sensor network was designed, and a management and query mode was proposed. This gateway took microprocessor AT91ARM9200 as the core chip, GoAhead Web Server as the embedded Web Server, and Sqlite as the embedded database. The interaction between Web server and Web browser was implemented through Common Gateway Interface (CGI). The reception and analysis of serial data were made with C program. This gateway has many advantages such as high efficiency of data-collection, high running-speed, and high credibility. It can manage and store the sensor network data effectively, therefore, achieving the remote query and supervision of the data in the wireless sensor network.
