2. Industry 4.0 and the Industrial Internet of Things
In the last few years, the IoT has rapidly expanded as an overarching concept that is used both to use extended Internet technology as a global network that interconnects various artifacts and to incorporate such a vision into technology (including, e.g., RFIDs, sensors, protocols for physical and network layers, etc.)
[3][4]. The IoT and IIoT, besides the digitalization of industrial manufacturing, can be considered as having instigated the fourth industrial revolution (Industry 4.0)
[5].
Several industries use the IoT. The redesign of the industrial IoT model will speed up the advent of the next industrial revolution, also known as “Industry 4.0”
[6][7][8].
One of the foremost characteristics of Industry 4.0 is the IIoT. The IIoT is supposed to be an excellent aspect of Industry 4.0, which will include highly efficient technology arrangements in many of the current industrial fields like transportation and manufacturing
[8][9]. In addition, the IoT is a component of the Industry 4.0 concept, which emphasizes the idea of consistent digitalization and connectivity between all productive units, while still retaining the advantages of the traditional manufacturing process
[9][10]. This section briefly reviews some points within Industry 4.0 and the IIoT. Some functions of Industry 4.0, the IIoT, and IoT are presented in
Figure 1 [11].
Figure 1. The IoT, IIoT, and Industry 4.0.
2.1. Industry 4.0
The term “Industry 4.0” refers to the fourth industrial revolution, which is characterized by the digitalization of the system’s physical assets as well as the smart development of goods through the use of internet-based technology
[12][13]. In the manufacturing fields, machines and sensors can be connected via the Internet to work better. Implementing Industry 4.0 would make devices and also sensors interconnected to the Internet; this makes the work easier.
Table 1 indicates how the industry improved from Industry 1.0, from 1784 to the present, with Industry 4.0 incorporating IoT technologies
[14].

Industry 4.0, which is a vital German ambition, intends to modify intelligent plant production technologies, transforming and upgrading these with cyber-physical systems (CPSs), the IoT, and cloud computing
[15][16][17]. It is necessary to include the IoT as an enabling tool for connecting and cooperating humsn in real-time with cloud-enabled infrastructure and cyber-physical systems, in the ongoing development that is currently guided by Industry 4.0
[18].
With the integration of advanced manufacturing systems with intelligent manufacturing processes, Industry 4.0 enables a new era in technology that fundamentally alters the supply chains, value chains of production, and business models of industries
[17]. Cloud services have helped to revolutionize unique IT cloud infrastructures that allow the representation of devices, which allow the incorporation of technological applications and AI bots
[18][19][20].
Aside from sensors, smart factories have successfully adopted many RFID applications
[21][22][23]. This technology is critical for improving a variety of industrial automation tasks, including automatic identification of products, instruments, and other production tools, as well as inbound/outbound tool management
[21][24][25].
The following examples will demonstrate the value of diverse and widespread uses in the automobile industry:
The traffic management system plays an important part in ensuring the nation’s economic stability
[26][27]. With the increasing number of vehicles on the road, intelligent traffic signal timing depending on vehicle density can be managed using the IoT, locally deployed RSUs, and security cameras
[26][28][29].
It informs the driver about the road condition (e.g., asphalt, wet, snow), traffic situation, and other unexpected information on the route, as well as emergency parking options
[26][30].
- 2.Real-time vehicle navigation
An IoT-based real-time car navigation system has a huge impact on guaranteeing a safe and efficient transportation system
[26][31].
When a vehicle encounters emergency issues such as an accident, an IoT-enabled model employing the SKM53 GPS module and the Haversine formula alerts the nearest rescue team for immediate assistance and speedy aid to victims
[26][32]. The IoT applications can also be used to track school buses
[26][33].
2.2. Industrial Internet of Things
The adoption of IoT technologies by the industry, the definition implemented by the German government in 2011 for the strategic planning of their manufactures, is also called IIoT or Industry 4.0
[3][34], in which today the new revolution of this industry is in use. To manufacture tangible products for the marketplace as well as to maintain the physical properties related to production, the Industrial IoT (or IIoT) should be understood as part of the larger IoT
[35]. The IIoT, in smart manufacturing systems, will be able to produce a revolution in the process industry
[35]. The IIoT can be considered one of the specific types of IoT; it is focused on its applications and use cases in modern industries and smart manufacturing, rather than on the Internet in general
[5].
The IIoT, in a manufacturing firm, is undeniably empowering the industrial revolution (Industry 4.0)
[36]. The IIoT differs from the customer IoT in that it focuses on interfacing smart gadgets in the fundamental framework, assembly, and procedure enterprises to create business points of interest
[35][37]. The IIoT can be used for IoT technologies in the manufacturing sector.
An IIoT environment cannot be complete without WSNs and WSANs, and middleware that can monitor them
[11]. More recently, the IIoT has emerged as an inferior model focused mainly on safety-critical applications in industrial operational applications
[38][39]. IIoT technology and data analytics utilize (record, monitor, manage) real-time data to facilitate and illuminate money-saving choices
[39]. In
Figure 2, a proposed architecture for the manufacturing industry IIoT is demonstrated
[40].
Figure 2. The proposed potential Industrial IoT (IIoT) architecture for the manufacturing industry.
According to
[41], the IIoT connects many points of tools, data, and people throughout industrial environments, and it provides numerous major benefits once established.
A key advantage that IIoT technology provides to its users is the ability to automate certain processes. Automated systems can be trained to conduct manual tasks that would normally be done by human workers on an assembly line using the IIoT. Automation in the IIoT reduces the amount of manual work that must be done by qualified personnel.
- 2.Maintenance and Safety
Automated predictive maintenance and safety monitoring in manufacturing lines are common uses of the IoT. IIoT sensors provide firms with the capacity to examine numerous elements of performance and identify whether equipment needs to be updated or replaced or whether a worker is in contact with harmful working circumstances. For the protection of goods in transit, IIoT sensors may also monitor environmental elements like temperature and air quality.
- 3.Real-Time Efficiencies
It is common to utilize the IIoT as a preventative measure to avoid downtime due to equipment failures and other performance concerns because of its emphasis on gathering as many real-time data points and insights as possible. Having less downtime in the workplace leads to improved productivity and efficiency in the workplace.
- 4.Workforce-Equipment Connectivity
Human workers run equipment in a more traditional factory or industrial setting, while automated machines follow their programming. The IIoT is one of the few technological solutions that breaks down barriers between workers and their equipment. Users acquire more direct insights from their tools, and tools learn over time as a result of human engagement.
3. IoT Marketplace
This section reviews some of the trends and facts related to the IoT technologies in the marketplace, and how the population has been affected in this area. Firstly, global pollution must be taken into consideration as this subject is directly linked with technology areas, especially nowadays.
It is undeniable that the population has increased throughout the world and that it will continue to grow at an alarming rate. Humans, devices, and “things” are all connected in the technology world, and population growth has had an impact on the number of interconnectors available, including those in the IoT technology domain as well. By 2020, nearly every person on the planet had more than six devices connected to the Internet, according to a report from Cisco
[42], which explains how the world population has grown in comparison to the number of connected devices per person over the period from 2003 to 2020, and demonstrates how the number of connected devices will increase dramatically. It was predicted that the number of devices that could be interconnected with one another would reach nearly 50 billion by 2021, which represents more than three times the number of devices that were connected in 2010 when 12.5 billion devices were connected
[42]. The population has a significant and direct relationship with new technologies, including the IoT, and this has had an impact on the number of smart devices that can be interconnected with one another on the one hand, and on the ability of the IoT to influence the marketplace on the other.
IoT technologies have emerged as one of the most important aspects of the environment’s domain; through the use of IoT technologies, millions of devices can communicate with one another and exchange information. As reported by Cisco
[42], the total number of Internet-connected devices is expected to exceed 50 billion by 2020. According to a report by
[43], one trillion networked sensors will be embedded in the world around us by 2022, with up to 45 trillion in 20 years.
While it is true that the number of interconnectors has increased as a result of new technologies, it should be noted that IoT technologies are also included in this topic. Using the infrastructure provided by the IoT domains, a massive number of devices and things can be connected to exchange information among themselves.
Aside from that, according to
[44], the comprehensive IoT and the number of interconnected devices within IoT areas is expected to grow significantly from year to year, reaching 75.44 billion globally by 2025, representing a five-fold increase in ten years.
Figure 3 shows IoT-connected devices were and are predicted to be installed worldwide from 2015 to 2025 (in billions)
[44].
Figure 3. IoT connected devices installed worldwide from 2015 to 2025 (in billions).
The IoT has advanced in a variety of areas over the years, and it is expected to continue to grow in the future. IoT technologies have become one of the most significant revolts in the digital domains on the commercial marketplaces for a variety of goods. Recently, the IoT has had an impact on a variety of areas in human life; it is clear that the IoT is a gateway to the marketplaces that is currently trending, and that IoT technologies have had an impact on the majority of marketplace sectors. Numerous factors have had an influence and are being tracked, including the growing environment, management, production, transportation, and markets, among others.
Because Microcontroller for IoT technologies has been thought by many companies from many countries, the trends of IoT technologies are growing in the field of marketplaces. Various devices can be used within the facility of the IoT marketplaces, and as mentioned by
[45], some of the IoT casting devices in the market are the Apple Airplay, Google Chromecast, and Amazon Firesticks.
In the IIoT sector, there is an increasing number of IT businesses, and some of the best providers have made the most progress: ABB, Cisco, Huawei, Intel, etc.
[41]. This is where the vast majority of IIoT use-cases are now being implemented. To improve their operational visibility and real-time data understanding, businesses are turning to leading IIoT providers.
A joint initiative between Huawei and DHL will focus on cell-based IoT technology that can link high numbers of devices over great distances with little power usage. Data and insight into warehousing operations, freight transportation, and last-mile delivery will be provided by enhanced connectivity, which will result in a more integrated logistics in the value chain
[41][46].

Wireless radio frequency identification technology is one of the techniques that can be used to connect everyday objects to computer networks
[6][49]. It is anticipated that RFID will continue to be the driving force behind the IoT, according to
[50][51]. RFID has the potential to transform dump devices into objects that are comparatively intelligent
[6]. According to
[52], the retail segment of the RFID market will have grown from $2.7 billion in 2018 to $5.4 billion by 2021, representing a compound annual growth rate of 38.9 percent over the forecast period.
RFID has dominated the marketing strategy since its inception, owing to its low cost and small size, as well as its widespread use
[51]. Economic fluctuation is another significant challenge impeding the more active development of the RFID market, particularly in market areas such as smart healthcare, smart cities, and smart transportation
[52]. RFID can be used in manufacturing for a variety of purposes, including supply chain management, production planning, and more
[53]
The IIoT is mostly used in manufacturing environments where automation plays an important role in success, but the technology is rapidly expanding in both capabilities and application cases
[41].
For industrial operations, the IIoT market alone is developing at a fast rate despite being just one aspect of the overall IoT industry. According to
[54], with a market size of roughly $216.13 billion in 2020, the worldwide IIoT market will reach about $1.1 trillion by 2028
[41].
The IoT is widely recognized as a cutting-edge technology that has the potential to transform the industrial sector
[53]. By using advanced technology for knowledge and production, intelligent manufacturing can create manufacturing processes that are scalable, efficient, and easily reconfigurable to meet the demands of a globally competitive market
[17][55]. Technology such as the IoT can enable manufacturing, as demonstrated by the German Industry 4.0 initiative, which has been influenced by the global economic environment in general.
As with a developing marketplace, IoT technologies have expanded to become a global market for the acquisition of illustrious products such as Google glasses and GPS shoes. A wireless sensor network, on the other hand, makes it possible for purchasers to access an electronic market from any location at any time. This is made possible by the facility of the electronic market. The field of wireless communications has seen significant advancements recently, particularly in the area of remote sensor networks, which have developed quickly and have been successfully implemented in the buyer electronics market
[56], once again, this has become a global market, particularly in light of the ability of IoT technologies to be deployed in the marketplace.
According to IDC, the IoT solutions are at the heart of the third platform’s vision. In recent years, the IoT solution has been introduced into the marketplace through a variety of techniques; as a result, these solutions can be implemented both economically and creatively, thus introducing the concept of the third platform.
Figure 4 describes innovative industry solutions and the IoT driving value throughout the third platform
[57].
Figure 4. IoT: Driving value throughout the third platform.
IoT Development Market: Exports of Connected Devices
As indicated by
[58], the growth of the IoT marketplace has been driven by communication among devices. Consistent with
[59], the IoT development market has seen growth in different periods from 2015, and that it is expected to continue up to 2030, while two points have been discussed concerning commercial and industrial electronics and consumers as well.
According to
[59], in general, the description of the IoT marketplace has been highlighted as below:
The primary scheme of an IoT business opportunity is to allow the owners of sensors and actuators to charge IoT application designers for the use of sensor-generated data and access to actuator capabilities. This type of commerce goes beyond the immediate needs of device owners and application engineers, allowing for the development of a new class of data-driven service contributors, where data processing and analysis can be provided to vendors and purchasers of IoT data by dealers, rather than the immediate needs of device owners and application engineers.
According to
[59], an intelligent IoT integrator (I3) must incorporate the following components to be a practical and successful commercial center:
-
The dealers post their accessible sensor-flowing information and actuators admit items alongside some hint of their worth and states of utilization.
-
Application designers and data/actuators admit purchasers to peruse or be suggested pertinent sensor data streams/device proprietors just as data intermediaries to interface with. This can be an index or potentially an endorsement instrument.
-
Motivating mechanisms for vendors to afford valuable data and actuators, for example, adaptation per unit amount of data for the actuator to acquire.
-
Directing ongoing data from sensor data sources to all purchasers that are approved dependent on the established understandings (counting installments, procedure arrangements).
-
Steering continuous activation and control signals from approved clients (purchasers) to actuators. Assurance and prestige evaluating and determining components for clients to rate each other. Metering and charging instruments to uphold advertising agreements being steered through the commerce.
-
APIs and SDKs for methodical admittance to different functionalities of the platform data naming and organizing capacities, just as security instruments to channel data.
The IoT marketplace consequently presents: proficient sharing/exchanging of data, advantageous arrangement and exchanges of data and access cost and utilization strategy models, and dataflow control to actualize the business perception
[59].
The research of
[60] has explained some examples of IoT marketplaces, including:
-
For the Internet of Vehicles (IoVs) to function, monetary transactions must be made between vehicle-to-vehicle networks, vehicle-to-roadside networks, and vehicle-to-infrastructure and pedestrian networks.
-
Smart Agriculture—Real-time crop information is available to farmers and other agricultural supply chain participants using this technology.
-
Smart Health—Data monetization is possible thanks to the wearable IoT (WIoT) devices used by patients, medical imaging, test results, social media, and external patient data that are collected by healthcare systems and patients alike.
