Service-Oriented Things: Delivering Smart Services Using Internet of Things

This paper presents a service-oriented paradigm for building next generation services using Internet of Things (IoT). In the future, there will be many IoT devices deployed in our environments, such as smart homes, smart offices, and smart factories. Our study proposes the paradigm of Service-Oriented Things (SOT) which can recognize user activities and compose, map and deploy context aware services in target areas. We have studied online activity recognition techniques to detect user activities. We have also designed IoT composition methods for creating virtual sensing services by integrating sesning data from multiple, correlated physical devices on edge servers. Our SOT service mapping and selection scheme then selects among the physical devices in a target location or virtual sensors over the network, to deliver services with high fidelity but low cost.
