Towards an Ontology for Supporting Dynamic Reconfiguration of IoT Applications

In the last years, several ontologies have been developed in the Internet of Things (IoT) domain to specify intelligent environments. Where, environment descriptions include both the software services, that expose the functionalities of devices; and resources, i.e. software components that control physical sensors and actuators, hosted on devices that sense or change the state of objects in the environment. This work proposes an ontological semantic network that supports the development of IoT applications that establish, at runtime, the binding with device services that allow them to fulfill their functionalities. This is done by enhancing device service descriptions with properties that allow inferring relationships among the attributes of the environment that an application is designed to control and the environment properties that device services are able to control. The applicability of the proposed model is shown through the population of the ontological network where an application establishes at runtime the binding among its functionalities and device services.
