ABSTRACT Hypertension continues to be a primary cause of global death, necessitating early and accurate forecasting for effective treatments. The existing methods have drawbacks such as class imbalance, poor modeling of sequential and spatial connections, high computation costs, and lack of interpretability, even though Deep Learning (DL) models offer possible solutions. To tackle these difficulties, we present VahigoNet, a novel blending DL model that incorporates vanilla recurrent neural networks (VRNN) for capturing temporal correlations, Google network for extracting hierarchical spatial features, and highway networks (HighwayNet) for adaptive feature refinements. To achieve strong generalization, we utilize the synthetic minority oversampling technique (SMOTE) for data balance. VahigoNet substantially outperforms baseline models, showing enhancements of 9.39% in accuracy, 10.27% in precision, 8.63% in recall, 9.39% in F1‐score, and 3.10% in area under the curve‐receiver operating characteristic. A 10‐fold cross validation method is utilized to assess the model's generalizability, markedly reducing overfitting and improving robustness. A paired t ‐test is performed to evaluate statistical significance, demonstrating that the enhancements are substantial and clinically relevant. Additionally, explainable artificial intelligence (AI) methodologies, including local Interpretable model‐agnostic explanations (LIME) and SHapley Additive exPlanations, are incorporated to provide both local and global perspectives on feature contributions. These explainability strategies enhance transparency, making VahigoNet a more interpretable and clinically reliable model for hypertension prediction. The results demonstrate that VahigoNet is an exceptionally efficient and transparent method, achieving a balance between predictive capability and practical relevance in medical diagnostics.

ABSTRACT Consumer Internet of Things (CIoT) has revolutionised agriculture by integrating intelligent computing, artificial intelligence and big data technologies in crop monitoring. This paper explores the application of intelligent computing and deep learning methodologies in crop monitoring within the CIoT framework. In CIoT‐based crop monitoring, a vision sensor collects real‐time data from crop leaf images.

Intelligent computing systems provide accurate disease classification, real‐time alerts, and actionable recommendations for optimised crop management practises. This advanced system empowers farmers to make data‐driven decisions, such as irrigation optimization, targeted pesticide application and nutrient supplementation, to maximise crop productivity and minimise losses. A benchmark dataset of leaf images is used, and a deep learning based model is presented for classifying healthy and diseased leaves. Experimental results demonstrate an accuracy rate of 0.98, with detailed validation, including dataset size and model parameters. Key benefits of intelligent computing in CIoT‐based crop monitoring include enhanced resource efficiency, reduced environmental impact, and improved sustainability. The paper also addresses the challenges of implementing AI and big data technologies, such as data privacy, security, interoperability and resource management in agricultural settings.

Digital twins is a virtual representation of a device and process that captures the physical properties of the environment and operational algorithms/techniques in the context of medical devices and technology. It may allow and facilitate healthcare organizations to determine ways to improve medical processes, enhance the patient experience, lower operating expenses, and extend the value of care. Considering the current pandemic situation of COVID-19, various medical devices, e.g., X-rays and CT scan machines and processes, are constantly being used to collect and analyze medical images. In this situation, while collecting and processing an extensive volume of data in the form of images, machines and processes sometimes suffer from system failures that can create critical issues for hospitals and patients. Thus, in this regard, we introduced a digital twin based smart healthcare system integrated with medical devices so that it can be utilized to collect information about the current health condition, configuration, and maintenance history of the device/machine/system. Furthermore, the medical images, i.e., X-rays, are further analyzed by a deep learning model to detect the infection of COVID-19. The designed system is based on Cascade RCNN architecture. In this architecture, detector stages are deeper and are more sequentially selective against close and small false positives. It is a multi stage extension of the Recurrent Convolution Neural Network (RCNN) model and sequentially trained using the output of one stage for the training of the other one. At each stage, the bounding boxes are adjusted in order to locate a suitable value of nearest false positives during training of the different stages. In this way, an arrangement of detectors is adjusted to increase Intersection over Union (IoU) that overcome the problem of overfitting. We trained the model for X-ray images as the model was previously trained on another data set. The developed system achieves good accuracy during the detection phase of the COVID-19. Experimental outcomes reveal the efficiency of the detection architecture, which gains a mean Average Precision (mAP) rate of 0.94.

Advancement in the Internet of Medical Things (IoMT), along with machine learning, deep learning, and artificial intelligence techniques, initiated a world of possibilities in healthcare. It has an extensive range of applications: when connected to the Internet, ordinary medical devices and sensors can collect valuable data, deep learning, and artificial intelligence techniques utilize this data and give an insight of symptoms, trends and enable remote care. Recently, Covid-19 pandemic outbreak caused the death of a large number of people. This virus has infected millions of people, and still, the rate of infected people is increasing day by day. Researchers are endeavoring to utilize medical images and deep learning-based models for the detection of Covid-19. Various techniques have been presented that utilize X-Ray images of the chest for the detection of Covid-19. However, the importance of regional-based convolutional neural networks (CNNs) is currently confined. Thus, this research aimed to introduce an IoT-based deep learning framework for early assessment of Covid-19. This framework can reduce the working pressure of medical experts/radiologists and contribute to the pandemic control. A deep learning-based model, i.e., faster regions with CNNs (Faster-RCNN) with ResNet-101, is applied on X-Ray images of the chest for Covid-19 detection. It uses region proposal network (RPN) to perform detection. By employing the model, we achieve a detection accuracy of 98%. Therefore, we believe that the system might be capable in order to assist medical expert/radiologist, to verify early assessment toward Covid-19.

The Internet of Things (IoT) widely supports the smart healthcare field; combined with computer vision, machine, and deep learning techniques; it provides fast and accurate services for automated patient discomfort monitoring/detection systems. Traditional patient monitoring systems are commonly composed of wearable sensors and vision-based methods. In this article, an IoT-based noninvasive automated patient's discomfort monitoring/detection system is presented and implemented, using a deep-learning-based algorithm. The system is based on an IP camera device; the patient's body's movement and posture are detected without using any wearable devices. The Mask-RCNN method is employed for the extraction of different key points on the patient body. These detected key points are then transformed into six major body organs using association rules of data mining. Furthermore, for analyzing the patient's discomfort, detected key point coordinates information is measured. Finally, the distance and the temporal threshold are applied to classify movements as either associated with normal or discomfort conditions. These key points information is also used to determine the postures of the patient lying on the bed. The patient's body position and posture are continuously monitored, based on which comfort and discomfort level are discriminated. For experimental evaluation, different video sequences are recorded covering two patient's beds. The experimental results show the proposed system's worth by achieving a true-positive rate of 94% and a false-positive rate of 7%.

The Internet of Things (IoT), with smart sensors, collects and generates big data streams for a wide range of applications. One of the important applications in this regard is video analytics which includes object detection. It has been considered as an important research area particularly after the development of deep neural networks. We demonstrate the applications, effectiveness, and efficiency of the convolutional neural network algorithms, i.e., Faster-RCNN and Mask-RCNN, to facilitate video analytics in the IoT domain, for overhead view multiple object detection and segmentation. We used the Faster-RCNN and Mask-RCNN models trained on the frontal view data set. To evaluate the performance of both algorithms, we used a newly recorded overhead view data set containing images of different objects having variation in field of view, background, illumination condition, poses, scales, sizes, angles, height, aspect ratio, and camera resolutions. Although the overhead view appearance of an object is significantly different as compared to a frontal view, even then the experimental results show the potential of the deep learning models by achieving the promising results. For Faster-RCNN, we achieved a true-positive rate (TPR) of 94% with a false-positive rate (FPR) of 0.4% for the overhead view images of persons, while for other objects the maximum obtained TPR is 92%. The Mask-RCNN model produced TPR of 93% with FPR of 0.5% for person images and maximum TPR of 92% for other objects. Furthermore, the detailed discussion is made on output results which highlights the challenges and possible future directions.

A top view camera having wide range lens installed overhead of the objects contributes greatly toward resolving the tracking problem and also maintains comprehensive visual access of the environment. Video analytics becoming more important to Internet of Things applications including automatic people monitoring and surveillance systems. We followed an approach based on machine learning features-based person tracking algorithm in industrial environment. The algorithm implements simple motion detection framework through motion blobs. The algorithm, rHOG uses the history of already imaged/blobed population with the anticipated blob position of the person observed. We have compared our results, acquired through five varying test sequences, with established algorithms used for object tracking. The results highlight that our algorithm beats others tracking algorithms by greater margins. The accuracy depicted in our results shows 99% of accuracy compared to the last known best algorithm, the mean shift algorithm, yielding 48% accuracy in result. Furthermore, unlike other blob-based tracking algorithms, our algorithm has additional property to discriminate any blob as a person or no person. Our proposed tracking algorithm has the additional advantage of detecting stationary person for a long time, handling occlusion, abrupt change in the environment, and keeps performing the tracking by compensating for the gaps in data pertaining to all the frames.

In this paper, we propose a relay selection strategy for randomly distributed multiple relays. A single relay is selected for transmitting signal from a fixed source to a fixed destination which requires minimum total transmit power. The lack of perfect channel state information (CSI) at the relay-destination link has been taken into consideration while selecting the relay. We consider the relay movement with low mobility features and evaluate the performance based on the total transmission power requirement. In addition, relay selection region is obtained to improve the overall performance of the system. Simulation results show that a similar performance in terms of total transmit power can be achieved at lower complexity if we select the relay from a specific relay selection region as compared to considering all the relays in the network.
