Abstract

Internet of Things (IoT) is an emerging domain that promises ubiquitous connection to the Internet, turning common objects into connected devices. The IoT paradigm is changing the way people interact with things around them. It paves the way to creating pervasively connected infrastructures to support innovative services and promises better flexibility and efficiency. Such advantages are attractive not only for consumer applications, but also for the industrial domain. Over the last few years, we have been witnessing the IoT paradigm making its way into the industry marketplace with purposely designed solutions. In this paper, we clarify the concepts of IoT, Industrial IoT, and Industry 4.0. We highlight the opportunities brought in by this paradigm shift as well as the challenges for its realization. In particular, we focus on the challenges associated with the need of energy efficiency, real-time performance, coexistence, interoperability, and security and privacy. We also provide a systematic overview of the state-of-the-art research efforts and potential research directions to solve Industrial IoT challenges.

CONCLUSION

This paper presented an overview of the emerging IIoT solutions. What is proposed as a revolution for the consumer market can be another step of the ever evolving industrial communications world. Several technologies are involved and terms as IoT, IIoT and Industry 4.0 are often misused. In this paper, we have provided a systematic overview of IIoT, focusing on the definition of its architecture and describing the protocol ecosystem which is emerging from standardization efforts. We have also discussed the challenges for its realization. Besides the QoS requirements that characterize industrial communications, IIoT suffers from yet to be considered security challenges that stem from the high sensitivity of the managed information. Furthermore, typical IIoT applications have to deal with constrained resources (both power and computing) and must be operative for extended periods of time, ensuring availability and reliability. We have described the state-of-theart research and standardization efforts and future research directions to address IIoT challenges.
