Introduction Internet of things - Web of things
◦ Integration of physical objects with the world wide web◦New business models (fulfill varying customer needs at real-time, personalized offers)
◦Certain advantages (monitoring, effective management, human-robot collaborations)
◦Most probably: IoT is the technology that will drive the future
