Evolution of IoT to IIoT: Applications & Challenges

Abstract

The emerging Internet of Things (IoT) provides a wide range of platform to different technologies by connecting different devices and are automated by using sensors. It builds a platform and is responsible for functioning of various smart devices over a range. After installing IoT in devices they are able to communicate with each other without involving human and computer interaction, it is also being widely used in all the fields as no human intervention is required in any IoT based applications. In this paper we present a survey of how IoT is transformed into IIoT (Industrial Internet of Things), what is Industry 4.0, what are key differences between IoT and IIoT, various application of IoT in different sectors, powerful features and advance characteristics of IoT. Since the demand of IoT systems is increasing in various fields day by day and ease of life after using smart devices but then also it possesses certain limitations too. The later part of paper focuses on security threats and issues addressed by IoT based systems along with ways to overcome the limitations possessed in the system.
