An Evolution of Innovations Protocols and Recent Technology in Industrial IoT
Industrial Internet of Things (IIoT) forms an interconnection between machines and functions with an internet connectivity. These IIoT devices enhance manufacturing or industrial process as they are interconnected with each other to perform industrial applications using intelligent industrial operations with advanced data analytics techniques. By using IIoT, the industries can be able to use real time supply chain methods for tracking status of materials, equipments, and products as they move out to consumers. This may interrelate the consumers, suppliers, and manufactures to get updated information about the product status in applications such as ERP, PLM, and other software systems. As we move from manpower to digital technology, IoT revolutionized the digital industry in the fields of agriculture, city infrastructure, medical care, and healthcare. However, IIoT has brought a next big boom in the business market with smart industrial technologies. At present, the industries leverage the benefits of IIoT in water industry for smart water management by enabling smart water meters, detectors, and irrigation methods. In case of oil and gas industries, IIoT devices help to reduce instant leakages and in case of any unavoidable situation alert systems are also used to maintain security for the employees. As an exponential growth, IIoTs witnessed in auto industry with some boarding impacts such as product tracing, transportation management, enhanced routes, and motorist behavior. The IIoT systems are used in integrated smart transportation system for following up the real time activities of the driver as well as the vehicle and notifying drivers regarding potential dangers on the roads. Even though healthcare is a vast ecosystem, the IoT has been adopted rapidly in healthcare monitoring, pharmaceutical industry, smart beds, biosensors, and other remote monitoring systems. In this, new digital transformation of industries to IIoT which uses secure operating protocols for an Open Platform Communication infrastructure. It uses IoT protocols for enhanced remote asset monitoring with increased operational efficiency and asset performance. IIoT uses a bunch of protocols chosen depending on the application or the so called Use Case. The most commonly used protocols are MQTT, CoAP, and HTTP. To cope with the disruptive technologies, business has embraced IIoT for significant improvements in terms of safety, efficiency, sensors, network, and data transmission. Thus, this chapter describes the protocols, new innovations, and present technologies used in industry.
