面向服务的传感器网络应用体系结构研究

An Service Oriented Architecture to Apply the Sensor Networks

集成了传感器、微机电系统和网络三大技术而形成的传感器网络是一种全新的信息获取和处理技术,其广泛的应用前景受到学术界和工业界的高度重视。传感器网络和Internet之间的互联以及应用成为研究的重点。面向服务的传感器网络应用体系结构,将传感器网络应用的接口和交互作为一种网页服务进行封装,用户可以通过HTTP来查找、定位和唤醒这些服务。描述了该体系结构的实验环境,并与典型应用场景相结合,融合核心服务和辅助服务。

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 copy with this challenge. The interfaces and interactions of the sensor networks with their applications are encapsulated as web services. Through services registry and advertisement, these services can be discovered ,＇ located and invoked by applications over HTTP. By defining a set 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 typical application scenario. Research works show that this is a promising technology which can enable the rapid development and deployment of the sensor network applications.
