The industrial internet of things (IIoT) is a group of interconnected sensors, instruments, and other smart devices. The IIoT network is responsible for data collection, exchange, as well as analysis. Examples for IIoT applications are drilling gear and research stations for cloud storage and analysis, the oil and gas industry, and so on. The IIoT is a collection of smart devices exploited to monitor the environment, collect the data from the environment, and exchange the data among various devices. Each IIoT comprises the following components that are connected devices, data communication infrastructure, analytics, data storage, and people.
   The connected devices can sense the environment and communicate the data. The data communication infrastructures are public and private. The analytics obtains the business data from raw IoT information. The storage the exploited to store the data generated from IIoT devices. Finally, the peoples are the entities. The data analysis in IIoT applications assists the companies in addressing the fluctuations in product demand and pricing. Moreover, it helps in minimizing the impact of security and privacy issues.
   By applying the geolocation and product monitoring smart sensors and thermal detectors, the IIoT improves the transportation process of oil and gas. It increases the safety of products and employees. It helps in forecasting the demand for products more accurately.
