Internet of Things for Manufacturing in the Context of Industry 4.0

Internet of Things (IoT) can be defined as "a world where physical objects are seamlessly integrated into the information network, and where the physical objects can become active participants in business processes. Services are available to interact with these 'smart objects' over the Internet, query their state and any information associated with them, taking into account security and privacy issues."The Internet of Things itself is enabled by a few key technologies which have had extensive progressive in the last few years. As the well world-wide spread of Industry 4.0, IoT-enabled manufacturing plays an important role in supporting smart factory, intelligent automation, and real-time adaptive decision-makings. This paper comprehensively review related technologies and world-wide movements so that insights and lessons could be useful for academia and practitioners when contemplating IoT technologies for upgrading and transforming traditional manufacturing into a Industry 4.0 future.
