基于Web服务的传感器网络和Internet集成

摘要

With the rapid development and wide applications of wireless sensor networks,the connection of sensor networks with their application through the Internet rises as a core challenge.Service-oriented architecture for software development can be used to deal with this challenge.The interfaces and interactions of the sensor networks with their applications ar encapsulated as web services.Throughservices registry and advertisement,these services can be discovered,located and invoked by applications over HTTP.By defining aset of core services to encapsulate the sensor networks and some auxiliary services,the sensor networks can be easily integrated into applications..These core services and some auxiliary services and implementation are presented,along with a brief discussion of a typicalapplication scenario.The research works show that it is promising technology which can enable the rapid development and deployment of the sensor network applications.%随着无线传感器网络的迅速发展和广泛应用,如何把传感器网络和应用系统通过Internet连接在一起就成了一个必须面对的挑战,SOA的软件体系结构是解决这一问题的有效方法.将无线传感器网络的访问封装成Web服务,通过服务注册和服务发现,应用程序可以通过HTTP发现,绑定和调用这些服务.通过定义一些核心服务和辅助服务,传感器网络可以很容易地集成到应用系统中.通过讨论这些核心服务和辅助服务及其实现,典型应用场景的介绍,证明了这种方法的有效性.
