Anomaly detection is critical to ensure the IoT (Internet of things) data infrastructures' Quality of Service. However, due to the complexity of incon-spicuous(indistinct) anomalies, high dynamicity, and lack of anomaly labels in the operational IoT systems and cloud infrastructures, multivariate time series anomaly detection becomes more difficult. Existing approaches are rarely effective in meeting these challenges. In this paper, We propose a novel convolutional adversarial model based on CNN adversarial training with POT (Peak Over threshold) dynamic threshold selection (CAT-POT) for multivariate time series anomaly detection in the IoT data. We build on the original autoencoder, replacing the fundamental linear changes with a convolutional neural network and adding a convolutional decoder to make an adversarial training architecture. the ability of the model to identify 'slight' anomalies is enhanced through adversarial training, combined with POT dynamically selected thresholds to detect anomalies. We conduct ex-periments on five subsets of various open datasets, and the overall performance of CAT-POT is better than that of the baseline method. the average F1 value of CAT-POT on all datasets is 0.889, which is 5.1% higher than the suboptimal model, with the best improvement reaching 21.5%. © 2022 ieee.

To improve communications network efficiency, situation identification is essential. the requirement for real-time scenario identification of vehicular communications is growing more pressing provided a certain vehicle movement makes vehicle interaction circumstances vibrant and that there are significant variations in signal propagation, vehicle speeds, and vehicular concentrations among possible situations. On the other hand, it has been demonstrated that cryptography methods are less effective at preventing insider attacks that originate inside the automotive communication network. A misbehaviour detection system has been found to be more effective in identifying and preventing insider attacks. this research study presents a misbehaviour detection system based on machine learning and is learned utilizing datasets produced by numerical simulations in a genuine vehicular distributed system. Vehicle communication systems may choose the proper spatial multiplexing and system integration by correctly detecting the current conditions in order to maintain an efficient and reliable operating condition. A back-propagation neural network (BPNN) is trained, and a scenario identification model is developed, using datasets that comprise channel properties acquired from channel measurements in various scenarios. Additionally, the proposed identification model's best performance-enabling model configuration technique is analysed and offered. the identification accuracy is then verified using validation information from the relevant circumstances. © 2023 ieee.

For this article, a hybrid domain multiple access (HDMA)-assisted visible light communication (VLC) system based on transmitting and reflecting reconfigurable intelligent surface (TR-RIS) is studied. HDMA is a new multiple access technology enjoying multi-domain signal information, which can effectively improve the system performance by carrying more users' information on the light emitting diodes (LEDs). Contrapose to the problem of multi-LED interference in the system, this paper introduces a transmitting RIS (T-RIS) angle diversity receiver (RADR) model, using the electronically controlled refractive index characteristics of the T-RIS and the angle diversity of the spatial optical signal, which can effectively alleviate interference problem between multiple LEDs. Furthermore, a system optimization model is proposed in this paper. Considering various constraints of the system, an optimization objective is established to maximize the communication capacity by optimizing the power distribution ratio and reflecting RIS (R-RIS) unit. the simulation results show that the proposed scheme can effectively improve the VLC system capacity compared to the existing ones. © 2023 ieee.

Digital technologies, such as wireless body area networks (WBANs) for mobile health (mHealth) applications, are expected to enhance the quality of the public health care system. Although mHealth can improve patients' quality of health by offering outpatient real-time health monitoring systems instead of being stuck in the hospital all the time to monitor chronic diseases. the major challenge in adopting mHealth is data security and privacy. the health data routed on the internet from the patient monitoring device to the health center for remote monitoring is vulnerable to confidentiality attacks. To handle this issue, we present an authentication scheme based on non-interactive zero-knowledge proof (NIZKP), which issues certificates and authenticates monitoring devices each time performing transactions without revealing sensitive information. Our authentication scheme provides a high level of security with a low computational cost, which is lightweight for WBANs. © 2022 ieee.

Nowadays, Alzheimer's disease is one of the most severe threats to people of all ages and socioeconomic backgrounds. their everyday activities may measure this disorder, and how they speak about it shows how concerned they are about it. the way we live today is different from how it was in the past because of our working environment and the lack of opportunities to interact with people. WHO estimates that about 10 billion individuals perish each year due to Alzheimer's disease since not been appropriately diagnosed and treated. An advanced Machine Learning-based recognition system design performs in this research work. the proposed model has been designed based on the human being EEG dataset(testing) and the Kaggle Alzheimer dataset (training). the developed intelligent system will be updated with data collection and pre-processing through the Random Forest machine model to locate our health condition and recognize daily routine changes. Only by developing a machine-based approach will we be able to discover Alzheimer's patients who previously had no idea that they had the illness and are now unable to reverse the progression of their condition. the designed application has attained a sensitivity of 93.01%, an accuracy of 91.32%, a recall of 97.28%, and a detection rate of 98.91%. the implemented application is beneficial to investigators and surgeons for easy treatment. the proposed RFO Machine learning design competes with present technology and outperforms methodology. © 2023 ieee.

Given the cursive structure of the writing and the similarity in shape of the letters, Telugu handwritten character identification is an interesting topic. the lack of Telugu-related handwritten datasets has slowed the development of handwritten word recognizers and forced researchers to compare various approaches. Modern deep neural networks find it difficult because they often need hundreds or thousands of photos per class. It has been demonstrated that learning important aspects of machine learning systems can be computationally expensive and challenging when there is a limited amount of data available. this research analysis work proposes a use case on the pre-existing model called EfficientNet and on top of that a custom pooling layer is added to check the trend as the dataset size increases of Telugu characters. the dataset has been divided into three categories, namely, Vowels only dataset, Consonant only dataset, and All character dataset. Proposed model was trained with a considerable amount of dataset containing half a thousand of handwritten Telugu characters and has produced some fascinating results which were worth observing. the accuracies had followed a certain trend. the model was tested on the dataset collected, which were filtered out to record any performance improvement and improvement was observed, where average accuracy went from 55% to 92%. © 2023 ieee.

the Internet of things (IoT)-based remote health monitoring is one of the most promising technological interventions that is emerging to address the unique challenges of affordability, accessibility, and availability in global health, which denote equitable access to healthcare, particularly in remote-rural-developing regions. IoT devices can monitor multiple vital signs, which are then used for AI-assisted decision-making systems, which in turn assist physicians in forecasting remotely. However, there are many difficulties, like bandwidth issues, data loss, and overburdened doctors due to the massive amount of data. Shifting data from cloud to edge improves performance, cost efficiency, privacy, reduces communication between distant servers and the edge, resulting in less processing delay. We developed a clinical response requirement based cloud-to-edge offloading technique. As a use case, we developed an edge AI application for acute hypotensive episode prediction and compared its performance both in the cloud as well as on the edge. © 2023 ieee.

Human beings have the ability to identify a particular event occurring in a surrounding based on sound cues even when no visual scenes are presented. Sound events are the auditory cues that are present in a surrounding. Sound event detection (SED) is the process of determining the beginning and end of sound events as well as a textual label for the event. the term sound source localization (SSL) refers to the process of identifying the spatial location of a sound occurrence in addition to the SED. the integrated task of SED and SSL is known as Sound Event Localization and Detection (SELD). In this proposed work, three different deep learning architectures are explored to perform SELD. the three deep learning architectures are SELDNet, D-SELDNet (Depthwise Convolution), and T-SELDNet (Transpose Convolution). Two sets of features are used to perform SED and Direction-of-Arrival (DOA) estimation tasks in this work. D-SELDNet uses a Depthwise convolution layer which helps reduce the model's complexity in terms of computation time. T-SELDNet uses Transpose Convolution, which helps in learning better discriminative features by retaining the input size and not losing necessary information from the input. the proposed method is evaluated on the First-order Ambisonic (FOA) array format of the TAU-NIGENS Spatial Sound Events 2020 dataset. An improvement has been observed as compared to the existing SELD systems with the proposed T-SELDNet. © 2023 ieee.

Video anomaly detection (VAD) aims to use computer technology to automatically detect and recognize abnormal patterns in videos. Based on multi-instance learning, a weakly supervised anomaly detection method treats training videos as bags and assigns video labels by selecting key video segments from the bags to achieve fine-grained classification of video frames. Videos contain rich temporal information, and previous works model the global temporal information of videos to detect anomalies. However, monitoring videos usually have long duration and contain a lot of redundant information. therefore, this paper proposes a local attention module that integrates video segments of different lengths through four different masking mechanisms to guide the network to model short-term temporal relationships in videos, abandoning the global modeling approach. Additionally, a joint distance metric ranking loss is proposed to guide the network to generate more discriminative feature representations for better anomaly detection performance. the proposed method is extensively tested on two publicly available anomaly detection datasets and its effectiveness is validated. © 2023 ieee.
