Recent advances in technologies such as RFID, sensor networks and NFC are bringing the vision of the Internet of Things – intelligent data-enabled devices connected to the pervasive internet infrastructure – closer to reality. Creating the Internet of Things has many emerging challenges: the integration and management of heterogeneous data, the integration and transfer of enriched data, the effective use of knowledge-based decision systems, retrieval and sharing of knowledge automatically from huge volumes of data, ensuring security and protecting privacy. This international workshop provides the growing technical and scientific community developing around the Internet of Things with a dedicated high-quality forum where the latest research findings around identification, information and knowledge can be exchanged, new developments can be explored and real-world systems can be discussed.
