In this paper, we investigate a speech transmission system with timbre restoration and semantic recovery, which is referred to as a timbre and semantic recovery semantic communication system (TSR-SC). Specifically, to mitigate the inevitable degradation of audio signals during transmissions, a semantic extraction module is utilized to transcribe the audio into text sequences, which are then represented via semantic embeddings. To preserve acoustic characteristics such as intonation and speaking rate, during the transmission, the timbre of the original speech is extracted as prior knowledge to finetune the speech generation module at the receiver. This enables the generated speech to closely resemble the original one in tone and speed. Experimental results demonstrate that TSR-SC significantly outperforms traditional methods in terms of speech quality and timbre restoration.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"28 4","pages":"523-535"},"PeriodicalIF":3.0,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11606630","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149097726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing single-layer artificial neural network (ANN) model (i.e., ZMAD) performs well on familiar data; however, it has limitations over datasets with different distributions and advanced attack vectors. This paper introduces ZENA, a lightweight protocol-aware anomaly-based intrusion detection model for Z-Wave networks, which employs a multilayer ANN, built from scratch, to improve detection accuracy and robustness. Using a dataset with several attack classes and adversarial generated vectors, the proposed model achieves a precision rate of 95%, significantly outperforming ZMAD and state-of-the-art deep learning neural networks on same dataset (i.e., 89–93%).

Traditionally, these problems are optimized separately. In this paper, we present a multi-objective optimization model that addresses both issues concurrently, enhancing its relevance for real-world applications such as seabed monitoring, tactical surveillance, and traffic direction systems in 3D WSNs, where balancing coverage and energy efficiency is critical. While conventional intelligent optimization algorithms (e.g., PSO, GWO) often excel in benchmark function tests, they struggle with premature convergence and computational inefficiency in practical engineering problems like WSN deployment. Therefore, we propose a novel heuristic optimization algorithm with low computational complexity, termed the imitator-inspired optimization algorithm (IOA). To validate IOA's single-objective optimization performance, it is applied to coverage optimization in 2D WSNs and compared with five other popular algorithms. For energy-efficient coverage enhancement in 3D WSNs, we introduce a multi-objective imitator-inspired optimization algorithm (MOIOA), which simultaneously optimizes the conflicting objectives of coverage and energy consumption. MOIOA's performance is benchmarked against three well-known multi-objective algorithms. Simulation results demonstrate that the proposed algorithms exhibit both reliability and superiority in single-objective and multi-objective optimization, effectively solving the energy-efficient coverage enhancement problem in 3D WSNs.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"28 3","pages":"329-338"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11482798","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148442568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

STDMA has been used in industry for ship navigation, in automatic identification system (AIS), air traffic navigation in VHF data link Mode 4 (VDL Mode 4) and also proposed for the vehicular ad-hoc network (VANET) & unmanned aerial vehicle (UAV) communication systems. In this research, an enhancement to STDMA protocol has been proposed, termed as AG-STDMA, that is based on the use of geometric probability distribution instead of uniform probability distribution used in STDMA protocol, selection of slots for candidate set (CS) compilation based on timeout values in ascending order and unique slot placement methodology for free and externally allocated slots when number of free slots in the CS are less than the protocol threshold WCS<inf>min</inf>. The placement of slots according to timeout values in ascending order ensures that transmission slot selection using geometric distribution will result in transmission collision for low duration period as compared to the existing STDMA protocol, even if an externally allocated slot is selected, since the externally allocated slot will be in a free state much sooner as the slots with low timeout values are included in CS. This novel methodology provides improved results in comparison to existing STDMA protocol. Moreover, a mathematical model has been developed for obtaining optimum value for the geometric probability distribution parameter (α) that verifies simulation results. Percentage decrease ranging from approximately 27% to 58% and approximately 18% to 77% has been achieved for Transmission Collisions and Channel Access Delay respectively, justifying the use of AG-STDMA instead of STDMA protocol for future deployment in the communication systems.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"28 3","pages":"312-328"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11482797","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148442738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we investigate the physical layer security of SaRNs in multiple-relay and multiple-eavesdropper scenarios, and the effects of hardware impairments (HIs), eavesdropper mobility, and imperfect channel state information (CSI) are considered. Specifically, a SaRN transmission framework with the mixed decode-and-forward satellite/terahertz (THz) link is proposed, where the satellite link transmits information from a geosynchronous earth orbit (GEO) satellite to relays, while the THz links support communication between relays and indoor users. Two wiretapping cases are analyzed: Case I, where the eavesdroppers overhear the satellite-to-relay (S-R) transmissions; and Case II, where the eavesdroppers intercept both the S-R and relay-to-destination (R-D) transmissions. For two wiretapping cases, expressions of secrecy outage probability (SOP) and average secrecy capacity (ASC) under HIs, eavesdropper mobility, and imperfect CSI conditions are derived separately. The results show that the secrecy performance is related to the number of relays and eavesdroppers, HIs level, eavesdropper mobility, channel conditions, and the antenna configuration. Moreover, for the ideal cases of ideal hardware, static eavesdropping, and perfect CSI, we obtain exact expressions for SOP and ASC in terms of the Fox's H-function and their corresponding asymptotic results. The asymptotic analysis shows that the diversity gain of the system under both cases depends on the number of relays and parameters of the THz links.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"28 3","pages":"288-303"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11482795","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148442470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since multicasting is heavily constrained by the weakest channel gain of involved IoT devices, an advanced resource allocation strategy is required to enhance energy efficiency. This paper investigates a simultaneous optimization of power allocation and subchannel assignment to maximize energy efficiency in HMA, not resorting to alternating optimization (AO). Specifically, an optimization problem is formulated as a mixed-integer nonlinear programming (MINLP) problem, posing a significant challenge in finding a globally optimal solution. To address this, we propose two novel algorithms: the first is designed for small search spaces, using the Big-M method for linearization of a bilinear term followed by an iterative and threshold-based rounding, and the second is tailored for large search spaces, utilizing a hybrid proximal policy optimization (HPPO) technique to train hybrid action space.

However, conventional fast Fourier transform (FFT)-based OFDM suffers from critical limitations, including a high peak-to-average power ratio (PAPR), spectral inefficiency due to slow out-of-band emission (OOBE) decay, and sensitivity to synchronization errors. This paper introduces a novel multicarrier waveform, contourlet transform-OFDM (ConT-OFDM), which replaces the conventional FFT/IFFT pair with the inverse discrete contourlet transform (IDConT) and discrete contourlet transform (DConT) of the proposed method successfully adapts the DConT's multi-resolution and directional filter bank structure, which was originally designed for 2D image processing, to 1D communication signals to enhance time-frequency localization and spectral containment. A rigorous comparative analysis was conducted across key performance metrics, focusing on the highly demanding Rayleigh fading channel. The results, supported by theoretical analysis, demonstrate that DConT-OFDM offers: superior performance in terms of bit error rate (BER) and symbol error rate (SER) due to its inherent interference suppression capabilities, a significant reduction in PAPR, and enhanced power spectral density (PSD) characteristics. Crucially, by substituting FFT's sinc-based windowing with the sophisticated, compactly supported filters of the DConT, the system achieves these gains with a substantially lower linear computational complexity of O(N) compared to the O(N log N) complexity of FFT-OFDM, thus positioning DConT-OFDM as an efficient and robust filter-bank multicarrier (FBMC) alternative for future broadband wireless systems.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"28 3","pages":"304-311"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11482796","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148442753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a novel dynamic heterogeneous operating environment (DHOE) based security architecture of OBU is proposed, which is the first structure to use heterogeneous application containers to hold OBU application programs, with a dynamic model that is able to detect the security state and switch the online/offline application containers to enhance security. Through the heterogeneous processing units and dynamic switching scheme, DHOE is able to detect and mitigate security problems and provide a credible operating environment for OBU applications. The proposed DHOE architecture has been successfully integrated into a real-world OBU product and applied in the Yutong¯ test vehicle. The Markov chain based theoretical analysis proves the security performance of DHOE in a quantitative way; while the case study and performance evaluation results on the real-world OBU product show that the proposed DHOE architecture could greatly improve the OBU security level while only 16.3% extra CPU loads and 1.6% extra RAM memory costs are introduced.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"28 3","pages":"354-364"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11454667","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148442251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do so, there is the need to overcome the intrinsic challenges of this environment, represented by the strong attenuations and temporal variations caused by the optical properties of the underwater medium. Hence, the feasibility of an underwater communication system necessarily passes through the ability to model the underwater channel and design a system that is resilient to this environment. In particular, the main task is to characterize the turbulence and the channel impulse response, having both a major impact on the power fading and waveform distortions experienced by the transmitted signal during the packet communication. In this work, we propose a comprehensive model for the attenuation of the underwater medium focusing on the effect of turbulence and scattering within the marine environment and their impact on the temporal response of the whole system. Then, we summarize these results in the turbulence random process model and the channel impulse response. We also analyze the performances of the system using the most important figures of merit, such as the average bit error rate (BER), ergodic capacity, outage probability and capacity, and analyze the temporal distortion of the received waveforms, using the scatter plots and the eye diagrams.
