The smart technological advances in particular those related to the connected mobile devices play an elite role in today's smart world. In this paper, we introduce a novel Internet of Things (IoT) framework, "CAN things" (Context-Aware Networks for the Design of Connected Things) to identify IoT needs. CAN things proposes to use ontologies for standardizing data from heterogeneous objects. This paper presents a merging methodology for OWL ontologies, in order to make possible using various existing ontologies for CAN things' master ontology. Our goal is to make the presented framework a standard framework that can be used in high level research and industry projects.
