摘要：
伴随着日益增长的物联网服务，各类信息服务的整合成为物联网成功应用的关键。服务执行环境将从大而全的个体服务模式转向泛在多终端节点设备多而广的协同服务模式，而这正是导致大量新型业务和服务喷涌而出的根本原因。物联网服务聚合，通过特定的开发平台和工具，聚集多领域的资源和能力，整合各种信息、内容和应用，将不同业务和服务有机地结合在一起，形成适应环境变化的个性化服务，满足企业和用户泛在化和一体化的需求，并为企业和客户创造额外价值。本文先介绍了网络服务聚合方法的模型和分类，然后在物联网平台环境下，通过具体的服务聚合，实现了在特定场合的业务需求。

Abstract：
With the growing service on the Internet of things(IoT),the integration of various information service has become the key to the successful application of the IoT. Service execution environment will transform from the large individual service model to the ubiquitous collaborative service model which is equited with a wide range of multi terminal nodes.This is the fundamental reason leading to a large number of new services.Service composition on IoT,which is by specific development platform and tools,aggregates multi areas' resources,integrates all kinds of infromations,contents and applications. It combines different businesses and services to make the personalized service which is adaptable to changing environment as well as meet the needs of enterprises and customers,and it can also creat additional value for them.This article firstly introduces taxonomy of Web service composition models and approches,and then propose a concrete service composition in the IoT environment to meet the business need of specific situation.
