Hyperdimensional Cognitive Computing for Lightweight Cyberattack Detection in Industrial Internet of Things

Today's systems, especially in the age of federated learning, rely on sending all the data to the cloud, and then use complex algorithms, such as Deep Neural Networks, which require billions of parameters and many hours to train a model. In contrast, the human brain can do much of this learning effortlessly. Hyperdimensional (HD) Computing aims to mimic the behavior of the human brain by utilizing high dimensional representations. This leads to various desirable properties that other Machine Learning (ML) algorithms lack such as: robustness to noise in the system and simple, highly parallel operations. In this paper, we propose HyDREA, a HD computing system that is Robust, Efficient, and Accurate. To evaluate the feasibility of HyDREA in a federated learning environment with wireless communication noise, we utilize NS-3, a popular network simulator that models a real world environment with wireless communication noise. We found that HyDREA is 48× more robust to noise than other comparable ML algorithms. We additionally propose a Processing-in-Memory (PIM) architecture that adaptively changes the bitwidth of the model based on the signal to noise ratio (SNR) of the incoming sample to maintain the robustness of the HD model while achieving high accuracy and energy efficiency. Our results indicate that our proposed system loses less than 1% classification accuracy, even in scenarios with an SNR of 6.64. Our PIM architecture is also able to achieve 255× better energy efficiency and speed up execution time by 28× compared to the baseline PIM architecture.

Moreover, resilience is used to introduce the system dependability of the IIoT network. The simulation results show that the proposed production-centric IIoT system with a digital twin network can achieve improved dependability for the IIoT system compared with the traditional scheme.

The industry has undergone a digital transformation facilitated by the Industrial Internet of Things (IIoT) technology, ushering in the era of Industry 4.0. However, the widespread use of IIoT devices, such as sensors, robots, and other IIoT technologies, has made IIoT systems and associated services vulnerable to a range of network-based attacks, which can impede their performance and disrupt operations. Moreover, the automation process is essential for IoT-based industries to meet future demands. The concept of a zero-touch network has recently evolved to coordinate and manage network resources automatically. Machine learning (ML) plays a critical role in its architecture due to its ability to facilitate a close-loop automation process. With ML, analytical tasks and real-time predictions can be achieved effectively to build smart applications for the early detection of cyberattacks in IIoT systems. The ML components, such as preprocessing, training, and testing, can be subdivided into microservices to improve service while allowing interaction with edge and cloud services. In this article, we propose an ensemble learning-based intrusion detection system (IDS) for a zero-touch network automation process by leveraging ML and microservice technology to improve the trustworthiness of IIoT systems. More specifically, we use the feature selection technique to select significant features and pass them to different models, then blend their predictions based on a stacked ensemble learning approach. Experiments are conducted to evaluate the performance of the proposed framework compared to existing studies.

This study contributes to the improvement of intrusion detection and classification of cyberattacks in IIoT environments.

The rapid growth of the Internet and information technologies and also the diminution of the price of hardware components like wireless sensors leads to the fast growth in Wireless Sensor Network (WSN). The WSN is a bunch/group of sensors that are located across the area, in order to monitor and determine environmental conditions such as temperature, humidity, vibrations, wind, water levels, pollution levels. WSNs are susceptible to major attacks like Denial of Service (DOS), Wormhole attack, Sinkhole attack, etc. The main threat to the WSN is because of the broadcast nature of the nodes in the network. Therefore, the security of WSNs is the essential part that must be done. Hence, to overcome these problems or threats, we are trying to detect it using AI technology. With the expanding fields of Machine Learning and Deep Learning, we can apply various algorithms in order to classify different types of attacks. Once we detect the attack properly, we can prevent it accordingly. We are using WSN-DS. It has 4 classes of attacks which are Grayhole, Blackhole, TDMA(Scheduling), and Flooding which comes under the category of DOS attacks. In this chapter, we have analysed and compared the accuracies of 5 main machine learning classification algorithms. Also, we have analysed the 1 deep learning algorithm. The ANN (Artificial Neural Network) and 5 machine learning algorithms have been trained on the dataset. Furthermore, we have used K-fold cross-validation to get even more accurate predictions. After analysis of these algorithms, we came to the point that, the Machine Learning algorithms like Random Forest, Support Vector Machines and Deep Learning algorithm, namely, Artificial Neural Network can help us for detecting intrusions in the system or network. This will help researchers in designing their own machine learning model on top of our suggested model.

Industrial Internet of Things (IIoT) systems play a pivotal role in enabling real-time monitoring and analysis of equipment to prevent breakdowns and optimize performance. Predictive maintenance stands as a critical component of IIoT systems, allowing industries to anticipate equipment failures, minimize downtime, and enhance overall equipment effectiveness. This paper investigates the potential of Long Range (LoRa) technology in predictive maintenance applications within IIoT systems. Specifically, the study delves into the utilization of LoRa technology to bolster predictive maintenance capabilities, with a focus on a live prediction analysis demonstration conducted on an industrial robotic arm. The research presents a detailed test bed setup for conducting predictive maintenance, which involves capturing data from the robot, transmitting it to a LoRaWAN gateway, enabling prediction of normal or abnormal behavior in the robotic arm.

Knowledge inference using knowledge graphs is one of the recent research trends for fault diagnosis. As complex Industrial Internet of Things (IIoT) systems evolve to incorporate distributed subsystems, each subsystem may have local measurements interpreted by a local Knowledge Base (KB). In this work, we propose a distributed fault diagnosis framework with distributed path-based reasoning. In contrast to centralized reasoning that requires merging of the distributed KBs, the proposed framework employs a centralized coordinator to transfer the model among decentralized agents and allows an agent to handover training paths for others to continue training by filling in missing links using their local KBs. Our work is the very first distributed knowledge inference framework to reason among distributed fault diagnosis systems to tackle the KB isolation, scalability and flexibility issues of centralized fault diagnosis systems. To validate our framework with IIoT datasets, we build a fault knowledge graph from the Tennessee Eastman (TE) process simulations. Evaluations show that our framework outperforms the non-cooperative distributed reasoning method in terms of prediction accuracy. With the TE process dataset, the mean reciprocal rank is improved from 0.1612 to 0.19 with transferred models, and further to 0.206 with hand-over queries between agents.

Vibration-based prediction of residual fatigue life for composite laminates through frequency measurements

Deep Neural Networks (DNNs) have been extensively applied in the Industrial Internet of Things (IIoT) to support intelligent manufacturing and industrial automation. However, the limited computing and energy resources of IIoT devices hinder the efficiency of on-device DNN inference due to increased energy consumption and latency. To mitigate these limitations, collaborative inference and adaptive sampling techniques have emerged as effective approaches to dynamically allocate computational workloads between IIoT devices and edge servers, thereby reducing on-device burdens and improving overall system performance. In this paper, we propose an edge-assisted IIoT system that enables collaborative inference through a novel Diffusion Model-based Deep Reinforcement Learning (Diffusion-DRL) algorithm. The algorithm jointly optimizes sampling and task offloading strategy to minimize terminal energy consumption while ensuring inference accuracy and meeting latency requirements under complex constraints. By combining the generative power of the diffusion models with the decision-making capabilities of deep reinforcement learning, Diffusion-DRL effectively handles multi-dimensional discrete action spaces. Experimental results demonstrate that the proposed approach significantly reduces latency and energy consumption, while enhancing inference accuracy, offering an effective solution for intelligent collaborative inference in IIoT systems.

Several machine learning (ML) algorithms have been increasingly utilized for cardiovascular disease prediction. We aim to assess and summarize the overall predictive ability of ML algorithms in cardiovascular diseases. A comprehensive search strategy was designed and executed within the MEDLINE, Embase, and Scopus databases from database inception through March 15, 2019. The primary outcome was a composite of the predictive ability of ML algorithms of coronary artery disease, heart failure, stroke, and cardiac arrhythmias. Of 344 total studies identified, 103 cohorts, with a total of 3,377,318 individuals, met our inclusion criteria. For the prediction of coronary artery disease, boosting algorithms had a pooled area under the curve (AUC) of 0.88 (95% CI 0.84–0.91), and custom-built algorithms had a pooled AUC of 0.93 (95% CI 0.85–0.97). For the prediction of stroke, support vector machine (SVM) algorithms had a pooled AUC of 0.92 (95% CI 0.81–0.97), boosting algorithms had a pooled AUC of 0.91 (95% CI 0.81–0.96), and convolutional neural network (CNN) algorithms had a pooled AUC of 0.90 (95% CI 0.83–0.95). Although inadequate studies for each algorithm for meta-analytic methodology for both heart failure and cardiac arrhythmias because the confidence intervals overlap between different methods, showing no difference, SVM may outperform other algorithms in these areas. The predictive ability of ML algorithms in cardiovascular diseases is promising, particularly SVM and boosting algorithms. However, there is heterogeneity among ML algorithms in terms of multiple parameters. This information may assist clinicians in how to interpret data and implement optimal algorithms for their dataset.

The architecture of the Industrial Internet of Things (IIoT) system assumes the presence of a router as the main subsystem, which will allow connecting the subsystems into a single network and connecting them to the equipment of the Internet service provider. Failure of the router can lead to downtime of industrial equipment and the whole workshop at the industrial enterprise, and to the failure of the IIoT system as a whole. Control processing units of industrial routers (RCPU) are complex microprocessor systems (MS). Violation of their operability can be caused by both hardware (HW) and software (SW) failures. Therefore, to increase the reliability of RCPU it is reasonable to use such methods of reliability assurance as HW redundancy (duplication of processors with comparison of results), as well as the use of modern means of control and diagnostics. However, the number of HW and SW failures in RCPUs, is still quite high. In this connection, the solution of issues related to the development of methods for ensuring high reliability of RCPU is of great urgency. This paper proposes a method of ensuring the reliability of RCPU using SW diversity on the basis of priority series. The method let to choose the variant of redundancy of HW and the number of versions of SW as diversity in RCPU.
