Abstract: Under the support of Wireless Sensor Network（WSN）, broadband mobile communication, and embedded technology, Internet of Things（IoT） has been widely used in warehouses, smart homes and so on. However, the current system is not efficacious：the devices are private, and the systems are close coupling, so every particular application requires complex integration work, and therefore it needs more technical expertise, effort and time. It proposes an IoT service platform based on REST-style architecture in which the wireless sensors and sensing data are regarded as unified resources and facilitate heterogeneous system modules to mashup new applications under REST-style architecture. It gives the implementation details of the prototyping system and performance evaluation.

Key words: Internet of things, wireless sensor networks, REST, service platform

摘要： 随着传感网、无线通信、嵌入式系统等技术的发展，推动了物联网技术在诸如仓储物流、智能家庭等领域的应用。但是，现有系统一般都是独立开发，系统间相对较为孤立，存在着系统耦合性强，设备异构等弊端，使得新应用的创建需要复杂的集成工作。提出了一个基于REST架构风格的物联网服务平台，将传感节点等嵌入式设备和感知数据看作资源，使异构系统模块采用REST架构方式组建新型应用，同时设计了物联网服务平台的系统原型，，并给出具体的实现技术和系统验证。
