Industrial IoT: Overview, Enabled Technologies, Recent Case Studies & Challenges

Industrial Internet of Things (IIoT) has attracted a lot of scientific researchers. IIoT is being developed as a result of the Internet of Things (IoT) applications and the implementation of modern technical developments. By integrating smart devices for monitoring, sensing, gathering, interpreting, communicating and processing real-time events in industrial systems, IIoT emerged as a potential vision of IoT in the manufacturing sector. The main goal of IIoT is to accomplish high level efficiency, improve productivity and effective organization of industrial processes and assets through automated monitoring, product customization, optimizing machineries, preventive and predictive preservation of manufacturing tools and equipment. The basic architecture of IIoT, its components, its application, key enable technologies and challenges are described in this paper. Some recent IIoT case studies that are part of the research are also discussed in this survey paper.
