Towards an adaptive ontology based model for interoperability in internet of things (IoT)

Abstract

Interoperability is key in any networked system. In the IoT environments, the need is further amplified by the presence of numerous heterogeneous devices. To address device and service disparity, the things will need proper addressing, registration and de-registration. This can be implemented through abstraction technologies and models such as ontologies for semantic expressiveness. The aim of this paper is to investigate some of the requirements for semantic interoperability and expose some of the current challenges in device and service discovery. We also explore current models for resource discovery highlighting their strengths and weaknesses and how they can contribute to an ontology based IoT device and service discovery model. Furthermore, the paper concludes by proposing a model for device and service discovery.
