Abstract

Internet of Things should be able to integrate an extremely large amount of distributed and heterogeneous entities. To tackle heterogeneity, these entities will need to be consistently and formally represented and managed registered, aligned, composed and queried trough suitable abstraction technologies. Two distinct types of these entities are a sensing/actuating devices that observe some features of interest or act on some other entities call it 'smart entities', and b applications that utilize the data sensed from or sent to the smart entities call it 'control entities'. The aim of this paper is to present the Semantic Smart Gateway Framework for supporting semantic interoperability between these types of heterogeneous IoT entities. More specifically, the paper describes an ontology as the key technology for the abstraction and semantic registration of these entities, towards supporting their automated deployment. The paper also described the alignment of IoT entities and of their exchanged messages. More important, the paper presents a use case scenario and a proof-of-concept implementation.
