无线传感网网关Web服务中间件的设计与实现

Design and implementation of middleware of wireless sensor network gateway Web service

针对无线传感器网络现有后台管理界面通用性和可移植性差的问题,考虑了浏览器/服务器模式的优点,设计了介于Web服务器和无线传感器网络网关之间的Web服务中间件。该中间件具有2个接口,其中传感网侧接口和网关连接,采用标准化指令和网关进行通信,能够实现和底层通用无线传感器网络的连接;服务器侧接口和Web服务器通信,完成向上的数据转发。通过搭建实际网络测试验证了该设计的可行性和实用性。

Aiming at the problems of the poor versatility and portability of management interface for wireless sensor networks,considering the advantages of the browser/server mode,the middleware between the Web server and the gateway was designed.The middleware had two interfaces which were the sensor network side interface and the server side interface.The sensor network side interface communicating with gateway was designed by standardization,which connected with the versatile wireless sensor networks.The server side interface completing the data forwarding upward communicated with the Web server.Finally,the proposed scheme was demonstrated by experimental network test for its feasibility and practicality.
