Survey of Industrial Internet of Things (IIoT) in Industry Developments and Advanced Techniques

Machine-to-Machine (M2M), Machine-to-System, Cyber Physical System, and Intelligent Systems play crucial role in shaping the IoT technologies. The visual representation of the real world is generated by continuously scanning and monitoring various technological components in real-time through a gateway. This capability facilitates self-management and self-reconfiguration of devices, ultimately improving the Quality of Service. The integration of cloud-based SCADA (Supervisory Control and Data Acquisition) and MES (Manufacturing Execution System) services creates a standardized interface across diverse technological layers. One of the most significant challenges preventing the growth of the Internet of Things (IoT) is the increasing expertise of malicious sectors in the field of hacking. To address this issue, security measures were incorporated from the outset, encompassing comprehensive solutions. This review work focuses on the significance of the Industrial Internet of Things (IIoT) within industrial sectors and offers a concise overview of the evolving technologies to the IIoT techniques.
