Abstract

The adoption of emerging technological trends and applications of the Internet of Things (IoT) in the industrial systems is leading towards the development of Industrial IoT (IIoT). IIoT serves as a new vision of IoT in the industrial sector by automating smart objects for sensing, collecting, processing and communicating the real-time events in industrial systems. The major objective of IIoT is to achieve high operational efficiency, increased productivity, and better management of industrial assets and processes through product customization, intelligent monitoring applications for production floor shops and machine health, and predictive and preventive maintenance of industrial equipment. In this paper, we present a new and clear definition of IIoT, which can help the readers to understand the concept of IIoT. We have described the state-of-the-art research efforts in IIoT. Finally, we have highlighted the enabling technologies for IIoT and recent challenges faced by IIoT.

Introduction

The development of wireless technologies during the past decades has led to a novel paradigm called the Internet of Things termed as IoT. The IoT paradigm was firstly introduced by Kevin Ashton in 1998 as a concept for connecting things or objects to the Internet. Although IoT is believed to have a wide range of benefits in many IoT applications such as smart homes, healthcare, transportation and environment, it is also believed to have a significant impact in the industry by achieving more efficient, optimized monitoring and controlling with reduce cost. IoT is expected to bring innovations and benefits to the industry leading to the concept of IIoT. The IIoT system allows the industry to collect and analyze a large amount of data that can be used to improve the overall performance of industrial systems, providing various types of services. The IIoT system is also believed to bring cost reduction in Capital Expenditures (CAPEX) and Operating Expenses (OPEX). Many similar terms are coined to describe the concept of IoT into Industry, for example, Industry 4.0, Industrial IoT and Smart Manufacturing etc.
