【摘要】 设计并实现了基于B/S模式的传感器网络远程查询系统.通过把该查询系统划分为用户界面层、事物逻辑层和数据库层,层与层之间以组件完成信息的交互.用Java的Servlet方式和Applet分别进行服务器端和客户端的开发,并在实际的网络平台中实现测试相关系统功能.结果表明采用了基于Java平台的3层B/S模式,具有良好的可扩展性和较好的安全性.服务器和用户端分布式的处理数据方法可使系统具备良好的容错能力和负载平衡能力.更多还原

【Abstract】 The design and realization of sensor networks remote query system based on B/S mode are described.Query system is divided in three parts: user interface layer,object logic layer and database layer.They can transmit information with component.We detect all the function in application networks after developing server program and clients programs.The results indicate that it has good system expandability and security based on C/S mode.Distributed processing mode makes system have fault-tolerance and load balanced capacity.更多还原
