As the physical world is ever-changing,the sensor nodes provide the function of data collection in IOT past can not meet the services needed in real word are highly dynamic, diverse .effective and other characteristics. To solve the above problems, use the conception of SOA ( Service-Oriented Architecture) in the services application of IOT,the service components can be deployed,combined and applied. In addition,propose an description language SML (Service Model Language) of IOT service model based on XML. The language is used to describe the relationship between services to determine a flexible service model of service combination, in order to accelerate the speed of service model development and support the model to reuse, so that the service of things has better scalability and practicality.%由于物理世界的环境不断变更,物联网中原先传感节点仅提供数据采集的功能已不能满足现实应用中所需求的服务应具有的高度动态性、多样化等特性.为了解决上述问题,文中将面向服务架构SOA的概念应用于物联网业务应用,可以对应用组件进行部署、组合和使用.并且在此基础之上,提出一种基于XML的物联网业务模型描述语言SML,用来描述模型中服务之间的关联性,确定一个灵活的表示业务组合的模型,以加快业务模型的开发速度,支持模型的重用,使物联网业务具有更好的扩展性和实用性.
