Rich Device-Services (RDS): A Service-Oriented Approach to the Internet of Things (IoT)

The Internet of Things (IoT) should enable the seamless integration of devices to combine the data collected from the physical objects and yield new services. From the IoT perspective, every device can offer its functionality as one or more interoperable device-services. As the number of devices grows, and the number of interactions between their device-services is increased, achieving more scalable and dynamic integration of devices becomes a major challenge in IoT. An emerging approach to overcome this challenge is the application of service-oriented architecture. Over the last few years, Rich Services, which is a type of service-oriented architecture, has emerged as an excellent technique for facilitating integration of services in the large-scale systems. In this paper, inspired by the notion of Rich Services, we propose the Rich Device-Services approach to enable a scalable and dynamic integration of heterogeneous devices in IoT. The proposed approach exploits the Data Distribution Service middleware for publish-subscribe, data-centric, real-time, and loosely-coupled communication between device-services. We also present a sample of the proposed approach and analyze the performance of Rich Device-Services.
