Abstract

With the development of the Internet of things (IoT), billions of smart “things” with capabilities of sensing and actuating will be connected to the Web. The things are heterogeneous in function and interface, and how to manage those things with unified interfaces or methods becomes a primary and key issue in the IoT. In this paper, we expose each object capabilities as a web service and propose a resource-oriented service publishing method for devices in IoT. With the proposed ontology-based resource description model, various objects are abstracted as basic resources with multidimensional attributes. The basic resources are further combined into more complex resources to support practical business functions. All the resources will be published by the representational state transfer interface. To evaluate the proposal, we build a prototype system of smart office, and the results show that the designed system can support various business functions with high feasibility and efficiency.
