Semantic web technologies for internet of things semantic interoperability
Résumé
The rapid development of the Internet of Things has transformed our daily life by reaching all areas that we can imagine and does not stop evolving. It exchanges any information at anytime from anywhere. The Internet of Things is a set of physical objects carrying embedded technologies to gather data from their environment. The huge amount of raw data produced by different IoT devices is heterogeneous with different types and formats. As a result, sharing and reusing raw IoT data is a challenging task for IoT applications. The lack of interoperability in IoT systems creates a difficult issue that prevents them from functioning properly. To overcome this problem, data modelling and knowledge representation with semantic web technologies can be an adequate solution. In this paper we present a survey on the state of the art of current solutions to the problem of semantic interoperability in IoT systems and how semantic web technologies can be used to achieve the conceptual Internet of Things.
