Integration of Internet of Things (IoT) and blockchain combined with the power of Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL) are transforming the sphere of smart industries, propagating a new era of boosted productivity, information assurance, and data-influenced deliberation. Our research looks into how these cutting-edge technologies flow together to enable smart industry breakthroughs. This offers conductive connectiveness and communication capabilities between devices and can create large pools of data, that are essential for making more informed decisions and finally, operating more sustainably. This data is then scaled and processed by the AI ML and DL algorithm to get the predictive insights; process optimization and to improve on automation. The security and immutability of data are critical in an IoT network, and this is something that blockchain technology excels at and ensures data exchanged within these networks is safe and unalterable. Thanks to recent developments in AI, ML, and DL, they can now better meet the challenges of industrial applications well beyond predictive maintenance and supply chain optimization and extend into real-time monitoring and autonomous operations. The perspective taken in this research is instead one of a practical, real-world implementations, illustrating some of the advantages as well as challenges when integrating these technologies.

6.1 Introduction

The fourth industrial revolution is a trend that combine technological advancements in areas such as artificial intelligence (AI), big-data application and the Internet of Things (IoT), increased computational power and approaching almost ubiquitous connectivity (Bothra et al., 2023; Dhar Dwivedi et al., 2024). The integration of the IoT with blockchain technology and the synergy of AI, Machine Learning (ML), and Deep Learning (DL) are some of the game-changing elements that are playing a leading role in this new-age revolution (Parker, & Bach, 2020; Samad, et al., 2022; Saritha et al., 2021). The convergence of these technologies presents significant opportunities for intelligent, autonomous systems that can increase operational efficiency, safety, and data processing across different use cases in industrial segments. IoT connects devices fully and helps them collect data and communicate, all in real time (Katare et al., 2018; Ghosh et al., 2018; Radanliev et al., 2021). But this same interconnectedness poses serious data security, privacy and integrity issues. This is where blockchain technology comes to rescue as it creates a decentralized and immutable ledger of data transactions (Ekramifard et al., 2020; Zhang et al., 2021; Kumar et al., 2023; Paramesha et al., 2024a). When combined IoT and blockchain they together shape as a strong framework which is reliable, secure, and encourage effective data management (Atlam et al., 2020; Samad, et al., 2022; Dhar Dwivedi et al., 2024; Rane et al., 2024a). The utilization of AI/ML/DL is similar extension of this integrated framework. This data collected from IoT devices in a huge quantity can, in turn, be analysed, decipher and read by AI and ML algorithms, thereby providing insights and predictions about information, patterns and processes and help form decisions and ameliorate them. DL, a type of ML, uses neural networks to improve data, therefore, improving decision-making processes in today's complex world (Taye, 2023; Paramesha et al., 2024b). This creates the intelligent systems required in the new industrial landscape as IoT, blockchain, and AI technologies synergise with one another resulting in systems that can act with self-optimisation and autonomous decision-making capabilities. In this research, integration IoT and blockchain with AI, ML and DL works that make better understanding and identification of a combined potential of the intelligent industrial system.

Key contributions of this research work include:

• A systematic literature review providing an analysis of prior work that has combined IoT, blockchain, AI, ML and DL, surveying main trends and research gaps.
• Keyword analysis, and keywords co-occurrence in the literature, have been employed to uncover the focal areas of research and technology interplay.
• A cluster analysis divides the literature into different categories and provides information regarding the main research themes and how they are trending over the years.

6.2 Methodology

In this work we conducted a comprehensive literature review for IoT and blockchain integration for AI, ML and DL for dynamic industries. A detailed literature review was performed by searching through scholarly databases including IEEE Xplore, ScienceDirect, and Google Scholar. The search keywords were "IoT," "blockchain," "AI," "machine learning," "deep learning," and "intelligent industry." Following this, a key term type of content analysis was used to find the terms and phrases which repeated most often in the literature review selected. This included mining the text for keywords that appeared in the articles and calculating the frequency of the keywords to identify the main themes and patterns in research over time. Next, co-occurrence analysis was used to obtain scatters revealing how frequently these keywords appear together in each article. This analysis provided insights into the interrelations among different concepts and technologies that were presented in the literature. The cluster analysis divided the articles into different groups according to their co-occurrences. Clusters were visualized by VOSviewer and used for identifying the main research topics and trend hotspots in the intersection between IoT, blockchain, AI, ML, and DL under the intelligent industry background. This methodological framework offers a systematic way of interpreting what it is currently known and what are the likely future directions for this multi-disciplinary research area.

Internet of Things (IoT) Cluster:

Another important cluster, apart from the AI cluster is the cluster around IoT. This cluster is made out of Blockchain, ML, automation, cloud computing, edge computing, and industrial IoT. Blockchain, ML or any other similar technology IoT cluster demonstrates a perfect blend of IoT with this other cutting-edge technology. To use data gathering and transmitting, using the internet of things itself is vital, especially when combined with blockchain technology. By using these two together - data is secured and data stored across the country. This cluster explores the meeting point of AI and ML used to improve industrial processes, and the ways in which this process creates smarter, safer industrial environments.

Blockchain cluster:

IoT and blockchain are two sides of the same coin where blockchain is a must for IoT cluster as it can make data transfer between devices more secure and transparent. There are many concepts in Blockchain like smart contacts, cryptography, authentication, decentralization and Ethereum etc. The chain of custodies of the blockchain is vital for IoT networks to keep the data integrity. Smart sectors such as industries can utilize the blockchain to operate with security and reliability.

Machine learning and deep learning cluster:

AI and the Internet of Things revolve around the interconnected object detection of machine learning and deep learning. Major topics includes learning algorithms, reinforcement learning, deep reinforcement learning, long short-term memory, and optimizations. However, the data created by IoT devices are very large and machine learning and deep learning techniques are widely used to analyse and understand that data. Implementation of intelligent industry solutions requires the use of these technologies for the generation of predictive models and supporting the improvement of industrial processes.

Security and privacy cluster:

It is related to security and privacy, which are essential for both AI and blockchain - hence these two form a good combination. In the case of intelligent industry frameworks, data protection is the highest priority. This includes network security, intrusion detection, data privacy, access control, privacy-preserving techniques, and federated learning, among others. As we can see through the repeated use of these terms and related terms, a considerable emphasis is placed on advances in security measures to safeguard data privacy and prevent potential misuse of sensitive data through IoT and AI applications. This is a common notion known as federated learning where we can jointly train a model while keeping data privacy intact.

Sustainability and energy efficiency cluster:

These days many people have begun to understand the gravity of sustainability and energy efficiency. All these themes are interrelated, energy use, smart cities, energy efficient, and sustainability. The notions are interrelated, highlighting the increasing focus on sustainable and energy-efficient intelligent industry solutions. To achieve sustainable development and prevent environmental damage, renewable energy strategies and smart city initiatives are harnessing the power of AI and IoT.

Healthcare and medical services cluster:

Finally, a smaller cluster tends to home in on healthcare/medicine technology. The cluster is concentrated on the most important issues: health, diagnosis, medical services, internet of medical things, secure privacy. These cluster illustrate some of the ways AI, IoT and blockchain are impacting healthcare - improving the quality of medical services, enhancing diagnostic accuracy and protecting privacy with respect to health information. The figure points out the developing tendencies and priorities in the intelligent industries/socket, researching and developing around themes like industry 4.0, cybersecurity, sustainability or digital transformation. These are trends that touch on the basic industry goals - from automating processes to securing more digitally enabled environments, going green, and creating more digital ready enterprises.

Techniques for integrating IoT and Blockchain with AI, ML, and DL

IoT and AI Integration

IoT is all about data, and especially large-scale data with the verticals that involves with the connectivity of the devices, where having ML and DL or AI is enabling into that feature. IoT sensors provide constant data points that AI algorithms can process immediately for meaningful insights. In smart cities, AI analyses external data from IoT sensors to improve traffic, energy use, and public safety, among other things. ML algorithms can determine when infrastructure needs any maintenance based on the data streamed from various sensors by identifying patterns and anomalies. Edge computing is a familiar with technique where IoT is integrated with AI (Biswas, & Wang, 2023; Nguyen et al., 2024). Instead of sending all information for processing to a central cloud data center, edge computing processes data at the edge of the network where it is created. This reduces latency, bandwidth saving, high privacy. Edge-based AI models can analyse data in real time and even make decisions based on that processed data (Nguyen et al., 2024; Paramesha et al., 2024c). Such as in autonomous vehicles where edge AI could be used to analyse sensor data (input) to make real-time driving decisions (output). Table 6.1 shows the techniques for integrating IoT and Blockchain with AI, ML, and DL.

Blockchain and IoT Integration

Using blockchain along with IoT solves security and trust problems of IoT systems (Ekramifard et al., 2020; Zhang et al., 2021; Kumar et al., 2023; Paramesha et al., 2024d). By using Blockchain as the distributed and immutable ledger, any tampering of the data recorded by IoT devices it would not be possible. This is especially useful in supply chain management, as transparency and traceability are key. Products can be verified by blockchain which records every transaction from point of place of origin to the consumer (Ekramifard et al., 2020; Kumar et al., 2023). Smart Contracts are one way to concatenate the blockchain with the IoT (Shinde et al., 2023; Kumari, & Muthulakshmi, 2023; Rane et al., 2024b). Smart Contracts is a self-executing contract where terms are written into the code. They would enforce agreements so long as predefined conditions were met. So, in a supply chain scenario, an IoT sensor communicating with a smart contract can then allow the blockchain to confirm whether the shipment has arrived and trigger the release of cash (using a smart contract) to pay for the shipment, as an example. Beyond this, blockchain can further secure IoT using a more secured communication paradigm. The blockchain ensures that every IoT device has a unique and authenticated identity, and all communications between devices are also authenticated, encrypted and traceable (Ekramifard et al., 2020; Kumari, & Muthulakshmi, 2023). It can also help blockchain for secure and transparent data sharing among various stakeholders in the IoT ecosystem.

AI, ML, and DL in Blockchain networks

The use of AI, ML, and DL can greatly benefit the efficiency, security, and functionality of blockchain networks. AI algorithms can predict network congestion and speeds up transaction processing. This can help increase the security of the blockchain transactions as it can help in real-time detection of fraudulent activities/arbitrary activities overlaid on actual user activities using ML. DL provides the ability to analyse complicated data patterns and it can be used for improving the prediction models of blockchain applications (Tyagi, 2024; Mishra, & Chaurasiya, 2024). This approach entails employing AI to control and develop blockchain consensus protocols. On a more advanced note, consensus algorithms are crucial to safely validate transactions on a blockchain. Using AI to predict and tune the network parameters will optimise these processes to save energy and scale better. In addition to this, combining DL models with blockchain will strengthen data privacy and security. Federated learning (FL) is a DL method that enables training models in decentralized devices without sharing any raw data (Al Asqah, & Moulahi, 2023; Issa et al., 2023; Paramesha et al., 2024e).

Combining IoT, Blockchain, and AI

IoT, blockchain, and AI create a super synergy, which can disrupt multiple industries (Parker, & Bach, 2020; Saritha et al., 2021; Samad, et al., 2022; Bothra et al., 2023; Dhar Dwivedi et al., 2024;). An example could be the use of IoT devices to sense and monitor data of patients live, AI can be used to analyse data to provide personalized treatment plans, and blockchain can be used to store data in a secure way that make sure that patient data is secure and it includes patient data integrity. Agricultural work is divided in to two parts, first part is use as IoT sensors for the soil where AI can optimize the process of irrigation and fertilization and on the other end blockchain can be used for the authenticity of the agricultural products. Decentralized AI-powered IoT networks are a technical method to integrate these technologies. Blockchain is used to manage and secure IoT devices on these networks, and AI algorithms analyse the data created by these devices. For example, a smart grid where IoT sensors make the measurement of energy consumption, AI optimizes the energy distribution to a neighbourhood and blockchain secures the transactions between energy producers and consumers. Using AI is also one of the ways to help predict failure in industrial IoT systems for predictive maintenance. IoT sensors can track the health of a factory's machinery, AI predicts when a machine will need maintenance, and blockchain documents maintenance activities for transparency and traceability. This practical method minimizes downtime, extends the life of equipment, and increases operational efficiency.

Fig. 6.2 Industries and Sectors Requiring Supply Chain Management

List of industries and domains requiring supply chain management, a relatively broad application spectrum is included in Fig. 6.2. This includes retail industries, health industries, agricultural industries, automotive, fashion, energy, chemicals, and electronics industries, among many others. In each such industry, proper supply chain management is needed to ensure the flow of products and services from the production point to the consumer's hands effectively and efficiently. For instance, high speed and accuracy are required in the sectors of perishable goods and health, while construction and energy sectors need complex logic and supply strategies. The shades in the picture help reflect their relative importance or particular requirements in supply chain management within a specific industry. This diversity underlines that supply chain management practices have to be specifically oriented toward the peculiar needs of an industry, offering a critical perspective on adaptability and scope for supply chain strategies.

 

Architecture and system design

Integrating IoT, Blockchain and AI have some architectural considerations that are critical to be addressed in order to provide coordinated solutions with a desired rate of efficiency (Samad, et al., 2022; Bothra et al., 2023). Because IoT networks can involve millions of devices streaming data continuously and so are subject to sudden increases in traffic data, scalability is a very important property to have (Khan et al., 2023; Dhar Dwivedi et al., 2024). Its architecture should be such that it can be horizontally scaled means a greater number of nodes can be included to balance the data load, reduction in performance due to overheads in the system etc. This scalability is frequently facilitated by cloud-based services, which grant the flexibility to provision and de-provision resources as needed. Interoperability is one of the first concerns the need to be addressed with the richness of IoT devices and platforms (Khan et al., 2023; Tyagi, 2024). It must also use standard protocols and Application Programming Interface (API), so that these devices can communicate regardless of the manufacturer.

Crucial to pay special attention to security this concerns especially sensitive data. Using the blockchain introduces a compulsory ledger which makes modification impossible, but the privacy mechanisms featured must include encryption, authentication and access control in general architecture. Why to secure the edge devices is a big question for lots of industries using these devices as they are more vulnerable and more exposed to cyber-attacks. Large amount of data generated from IoT devices; hence efficient data management is very crucial. It has to be linked to the smart logic owner across the Internet from edge and can only pass the pre-processed data (clean filtered reading) with only useful info to the central server reducing the load of data transmitted to central servers.

Edge computing is an essential design principle that allows computation and data storage to be located at the IoT devices themselves. It also allows lower latency, faster processing of real-time data and less bandwidth needed to send data back to central servers. It relieves the cloud or blockchain network from hashing the data and using encryption bootstrapping process executed by the hashing algorithm in Blockchain moreover, it is responsible for the end-to-end software life cycle management. Edge nodes are used for pre-processing where data forwarding requires data analysis, filtering, and aggregation where the partially processed data which is small to be sent to the cloud or blockchain. A layered architecture allows for modularity, ease of integration. In this scenario, we have three layers: the edge, the fog, and the cloud. This represents a typical architecture. In edge layer, IoT devices and gateways gather and pre-process data. The fog layer contains intermediate nodes which are used for processing, storing locally and taking decisions to offload the cloud from these tasks. The cloud layer is made of centralized servers that run large scale data processing, ML training and also do the long-term storage.

The distributed nature of IoT networks is a perfect fit for a decentralized blockchain. Decentralized storage and processing help to mitigate backups and improve the robustness of a system. Smart contracts on blockchain can be coded to execute certain processes when some defined conditions are met advancing AI-infused decision making into the IoT ecosystem. Now we can deploy AI in system design which will help in predictive analysis and automation. Deployable from the edge to the cloud for predictive maintenance, anomaly detection and automated decision-making Federated learning, which allows a shared model to be trained across multiple decentralized nodes without raw data movement, is chosen due to its properties such as preserving user privacy and reducing communication overhead.

In order to automate the interactions between human and the blockchain, smart contracts are a necessity (Rane, et al., 2023a; Shinde et al., 2023; Kumari, & Muthulakshmi, 2023). Allow to apply restrictions, manage IoT device access rights and take AI actions, when specific conditions are met. Secure and cost-efficient smart contracts is a challenging task that needs a lot of coding practices, testing and careful implementation of logic to prevent bugs and loopholes in code based on the sides of vulnerabilities. At the edge, we need to deploy a lightweight model which can execute on small hardware stakes. Techniques such as model quantization, or pruning can reduce model size and computational requirement. Edge AI frameworks, like TensorFlow Lite and OpenVINO, are used to deploy models and optimize them for edge devices.

While immutability ensures data integrity over the blockchain, maintaining privacy again is required to be layered with new security provisions (Bothra et al., 2023; Dhar Dwivedi et al., 2024). To enable such an analysis, we can apply techniques like differential privacy and homomorphic encryption to keep data safe. Compliance with regulations is important, making sure that the way data is dealt meets the legal requirements. Frequent monitoring and maintenance are therefore required to maintain the system running well. When it comes to the things that can be monitored using these automated tools, they range from device health and network performance, to data flow, sending alerts, and suggesting actions to maintain the infrastructure on a proactive basis. It is the reason we need to receive regular updates and patches to offer better security and improvement functionality.

In general, such systems apply to underline hybridity in IoT applications, the goals of integrated control systems, and diverse application spots starting from healthcare up to smart cities. It finally outlines the impact on various sectors, which suggests that IoT technologies have a broad reach. The targeted domains are healthcare, smart cities, industry 4.0, smart agriculture, environment, smart homes, and innovative energy/grid management. Table 6.2 thus illustrates the multi conceptual nature of the IoT ecosystem, in which different technologies and paradigms find common ground to drive further development and application of IoT in various sectors.

Challenges in integrating IoT, Blockchain, and AI

Scalability is a significant issue for incorporating IoT, Blockchain, and AI together (Khan et al., 2023; Dhar Dwivedi et al., 2024). IoT networks can consist of millions of devices, which may produce large volumes of data. Blockchain itself, as a decentralized ledger system, offers a secure approach to include/write these data transactions, but has serious limitations at its current state. Existing Blockchain networks, like Bitcoin and Ethereum, are not built to process the vast scale of transactions required for Lifeliqe ecosystem. We are therefore investigating potential solutions such as sharding, off-chain transactions and exploring new consensus algorithms, but these are still experimental and will have to undergo rigorous testing to be considered ready for large-scale IoT deployments. Table 6.3 shows the challenges in integrating IoT, Blockchain, and AI.

There is another major concern for data privacy and security (Bothra et al., 2023; Dhar Dwivedi et al., 2024). Data generated through IoT devices are at high risk of getting breached because of their vulnerability towards hacking and cyber-attacks. Blockchain can support higher security levels by offering non-tamperable and verifiable log of all operations. However, this transparency can, however, be a double-edged sword, as the same exposure can also have privacy issues, especially if the information is sensitive. It is important to be able to implement privacy-preserving methods like zero-knowledge proofs and homomorphic encryption within the blockchain framework but it makes it more difficult to integrate. One of the biggest challenges is the interoperability of several systems and devices (Khan et al., 2023; Tyagi, 2024). IoT ecosystems consist of devices made by many different manufacturers, each using their own communication protocols and data formats. There is a need for standardization to make Blockchain and AI have meaningful interactions with this wide range of devices. At the moment, there is no globally accepted standard for IoT communication, leading to a complex breakthrough when developing a solution for seamless integration. Although organizations like the IEEE and the industrial internet consortium are trying to develop common standards, few have been broadly adopted.

Latency is also a major problem, especially when it comes to real-time applications (Mathur et al., 2023; Yadav et al., 2023). IoT devices are going to need to be always on and always responsive as they could be required to react to input or changes in the network at any time. Consensus mechanisms and data validation processes by definition add enormous latency to a blockchain. AI algorithms can also be particularly time-consuming, especially if they are performing complex calculations. This dilemma of fast IoT operations versus the secure, reliable processing needed for blockchain and AI is a dangerous playfield; ground that innovative solutions like hybrid systems touching upon the best parts of multiple worlds will need to tread. Regulatory and legal challenges cannot be ignored while the regulatory environments associated with blockchain, AI, and IoT are maturing, there is ample room for ambiguity and risk with regards to ownership, liability, and compliance. Global businesses have to understand that, regions have different regulations altogether making it a complicated. Organizations must adhere to these regulations in order to avoid any penalties, while also having the ability to innovate without causing too much disruption to the workflow.

6.4 Conclusions

Combining IoT and blockchain with AI, ML, and DL promises a revolutionary progression in intelligent industry. This convergence has opened up a new era in which the use of these technologies together provides unprecedented advantages in operational efficiency, security, and decision-making processes for different industries. But when IoT devices, blockchain and prospects of a trust space are combined, IoT data can be validated for authenticity, data access, and time. At the same time, AI, ML and DL algorithms rely on this vast data source to carry out complex predictive analytics, anomaly detection and automation in areas like predictive maintenance, quality assurance, and supply chain optimization. The recent changes demonstrate some of the interesting real-world gains of this connection. The decentralized ledger technology of blockchain is used in minimizing the risks in data breaches and tampering, this is also essential in industries demanding higher data security and higher trust. In comparison, AI and ML models are growing more sophisticated, creating more opportunities to train on live data and deliver more significant predictive and operational smarts. DL expands the range of applications by allowing for more advanced pattern recognition and decision-making processes. The adoption of it by sectors means a boundless automation, productivity and innovation capability. There is likely to be an increased focus on specific infrastructure refinements, scale issues and improvements in the interoperability between disparate systems in future research and development. Continual advancements in these technologies are expected to revamp these standards, creating smarter, more robust, and self-sufficient industrial realms.
