Motivated by the above, this paper employs an AAV as a mobile edge computing (MEC) server to provide task offloading services, based on which the non-orthogonal multiple access (NOMA) technology is used in AAV-enabled Internet of Vehicles (IoV). To reduce the MEC offloading delay, we propose a NOMA-enhanced MEC framework for AAV-enabled IoV. More explicitly, we formulate a total offloading delay minimization problem by optimizing the transmit power and the AAV position. To tackle the non-convex problem, we decouple it into two sub-problems: power allocation and AAV position optimization. Specifically, the power allocation is optimized via the successive convex optimization algorithm, and the AAV position is adjusted using the improved particle swarm optimization-genetic algorithm (PSO-GA). Then, we propose an iterative optimization algorithm to alternately iterate these two processes to find the optimal solution. Next, we analyze the achievable offloading probability of the NOMA-MEC scheme compared with the OMA-MEC scheme and derive its asymptotic expressions under high signal-to-noise ratio (SNR) conditions. Finally, simulation results indicate that the proposed scheme outperforms existing methods in reducing total offloading delay while validating the accuracy of performance analysis.","PeriodicalId":34270,"journal":{"name":"IEEE Open Journal of Vehicular Technology","volume":"6 ","pages":"2317-2331"},"PeriodicalIF":4.8,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11119075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field of wireless communications, deep learning, particularly Convolutional Neural Networks (CNNs), has been extensively utilized for tasks such as channel estimation and signal detection. However, CNNs' limited receptive field growth poses a challenge in capturing long range dependencies. To achieve efficient deep learning based OFDM-IM detection, this paper proposes two novel OFDM-IM signal detection networks that integrate wavelet transforms with CNNs (WTConv). The first proposed network, referred to as Dual Stage Wavelet Convolutions (DS-WTConv), adopts a dual stage architecture. It comprises an Index Feature Extraction Sub-Network (IdxNet) and a Signal Feature Reconstruction Sub-Network (DetNet). The second network, named Single Network Wavelet Convolutions (SN-WTConv), features a more compact single stage design that combines wavelet convolution and CNN layers. Extensive simulation results demonstrate that both the DS-WTConv and SN-WTConv networks exhibit superior bit error rate (BER) performance and lower computational complexity compared to existing conventional and deep learning-based approaches. Compared to the existing deep learning based detection schemes, the proposed WTConv-based networks reduce the BER by up to 35.3%, and the running time by up to 30.1%. Compared to the optimal Maximum likelihood (ML) method, the proposed DS-WTConv and SN-WTConv achieve approximately 19.2 times and 11.3 times faster runtime, respectively.","PeriodicalId":34270,"journal":{"name":"IEEE Open Journal of Vehicular Technology","volume":"6 ","pages":"2210-2223"},"PeriodicalIF":4.8,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11107403","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sophisticated polar decoding enhances the corresponding performance while degrading the coding rate and complexity. For better decoding performance and efficiency, this paper presents a polar coding scheme with selected index modulation (PC-SIM). At the transmitter, PC-SIM integrates the concept of index modulation (IM) into polar encoding, using the indices of inactive unfrozen positions (IUPs) to carry implicit information. To boost coding rate without sacrificing decoding performance, PC-SIM selects more reliable unfrozen positions for IM and adds inactive information bits (IIBs) to offset rate losses. Additionally, Walsh-Hadamard Transform (WHT) is incorporated to lower the high peak-to-average power ratio (PAPR) in multi-carrier systems and reduce interference. At the receiver, PC-SIM performs polar decoding followed by repetition decoding to obtain index bits and information bits. Simulation results indicate that in Orthogonal Frequency Division Multiplexing (OFDM) systems, compared to conventional polar codes and existing IM-aided polar coding schemes, the proposed PC-SIM scheme significantly improves error performance, coding rate, and PAPR reduction.

However, traditional centralized learning and federated learning (FL) face challenges in model convergence and performance degradation due to non-IID data distribution, privacy protection requirements, and communication bandwidth constraints among massive heterogeneous devices in V2X scenarios. To address these issues, this paper proposes a heterogeneous federated learning framework based on feature prototype alignment and generative knowledge transfer, enabling efficient and secure cross-device collaborative learning. The framework employs dynamic edge-enhanced contrastive learning on the server side to generate trainable global feature prototypes. These prototypes are subsequently decoded into composite images through a pre-trained generative adversarial network, achieving lightweight privacy-preserving knowledge transfer. Experimental results on CIFAR-10, CIFAR-100, and BelgiumTSC datasets demonstrate that our method achieves significant accuracy improvements compared with baseline approaches such as FedDistill and FedTGP.

This paper investigates a cooperative sensing problem within a multi-UAV framework, where multiple UAVs collaboratively perform energy detection for a set of ground targets (GTs). To evaluate the system's sensing accuracy, we use energy detection probability as the performance metric, with the objective of maximizing the network's overall detection probability through optimized UAV placement. Given the non-convex nature of the problem, we develop an efficient, low-complexity algorithm based on Gibbs Sampling (GS) to iteratively optimize UAV positions.

However, the increasing interconnectivity and reliance on digital components expose these vehicles to significant cybersecurity risks. To address these challenges, Zero Trust Architecture (ZTA) has emerged as a promising security framework. Operating on the principle of ‘never trust, always verify,’ ZTA offers a comprehensive approach to ensuring continuous trust verification in HEV systems. Despite its potential, the application of ZTA within cyber-physical vehicular systems remains underexplored, and its practical benefits and limitations are not yet fully understood by the engineering community. To bridge this gap, this article presents a detailed survey of ZTA tailored specifically to the needs of vehicular CPSs, highlighting existing technologies, security challenges, and the application of zero-trust principles in HEVs. Additionally, this work proposes a deep learning-based replay attack detection scheme for the battery management system (BMS) of HEVs. The approach leverages a deep learning model to estimate the battery's State of Charge (SoC), analyzing the Error of Estimation using the Inter-Quartile Range (IQR) technique. The detection system analyzes the Error of Estimation using the IQR technique, demonstrating a 74.25% containment ratio and detecting deviations up to 2.39 units during attack scenarios. The system maintains a balanced detection sensitivity with 25.75% detection density. While the proposed method demonstrates high effectiveness in detecting stealth replay attacks through simulation results, it faces certain limitations including computational overhead for real-time processing, dependence on high-quality training data, and potential vulnerability to adversarial attacks on the underlying deep learning model. These challenges highlight the need for careful consideration in practical implementations while opening avenues for future research.","PeriodicalId":34270,"journal":{"name":"IEEE Open Journal of Vehicular Technology","volume":"6 ","pages":"2171-2194"},"PeriodicalIF":4.8,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11091432","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Markov chain-based lane-switching mechanism enables realistic multi-lane traffic simulations with smooth centerline trajectories spanning straight and curved road segments. To further enhance robustness, an adaptive Minimum Variance Distortionless Response (MVDR) beamforming scheme compensates for beam misalignment and mitigates interference, thereby significantly improving the Signal-to-Interference-Plus-Noise Ratio (SINR).

However, recent studies that integrate reconfigurable intelligent surfaces (RIS) with UAVs tend to focus on limited aspects, such as single-UAV deployments or partial optimization of system parameters, thereby neglecting a comprehensive system-level design. To overcome these limitations, we propose a multi-user MISO communication network that leverages RIS-assisted UAVs to maximize both sum-rate and energy efficiency as two distinct objectives. Our approach stands out by considering multiple UAVs and incorporating four critical constraints: UAV flying areas, power limitations, transmit beamforming, and RIS requirements. We formulate separate optimization problems for sum-rate and energy efficiency, and address them using deep reinforcement learning (DRL) algorithms, namely proximal policy optimization (PPO) and deep deterministic policy gradient (DDPG). By jointly optimizing UAV coordinates, the transmit beamforming matrix, and RIS phase shifts, our method achieves significant performance improvements under dynamic environmental conditions. Extensive simulations show that our comprehensive strategy delivers higher sum-rates and enhanced energy efficiency, underscoring its practical potential for next-generation RIS-assisted UAV communication systems.","PeriodicalId":34270,"journal":{"name":"IEEE Open Journal of Vehicular Technology","volume":"6 ","pages":"2033-2047"},"PeriodicalIF":4.8,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11081475","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
