ETRFI dynamically allocates supplemental resources based on incremental throughput improvement and purification efficiency. In its second routing phase, entangled links are optimized to balance loss minimization and flow maximization. Furthermore, a time-slot control mechanism ensures synchronization and prevents decoherence during communication.

Firstly, we assess the queuing delay bound of frames, allowing bottleneck node to preemptively discard frames that are anticipated to expire. Secondly, we model the priority of different frames based on encoding referencing relationship and users' viewpoints, which helps to prioritize frames of each flow. Subsequently, we formulate an optimization problem to minimize the long-term quality loss caused by frame dropping, while adhering to per-flow quality assurance and total resource constraints. Considering the distinct timescales of network fluctuation and frame dropping, we propose a two-timescale hierarchical resource allocation scheme. On the long timescale, a resource allocation algorithm is designed based on queuing theory to calculate the resource demand of each flow. On the short timescale, to accommodate network fluctuations, a low-complexity heuristic algorithm is devised to adjust allocation results based on frame priority.

This is particularly beneficial for video, which dominates network traffic and demands high bandwidth and power, making semantic approaches ideal for conserving resources while maintaining quality. In this paper, we propose a Predictability-aware and Entropy-adaptive Neural Motion Estimation (PENME) method to address challenges related to high latency, high bitrate, and power consumption in video transmission. PENME makes per-frame decisions to select a residual motion extraction model, convolutional neural network, vision transformer, or optical flow, using a five-step policy based on motion strength, global motion consistency, peak sharpness, heterogeneity, and residual error. The residual motions are then transmitted to the receiver, where the frames are reconstructed via motion-compensated updates. Next, a selective diffusion-based refinement, the Latent Consistency Model (LCM-4), is applied on frames that trigger refinement due to low predictability or large residuals, while predictable frames skip refinement. PENME also allocates radio resource blocks with awareness of residual motion and channel state, reducing power consumption and bandwidth usage while maintaining high semantic similarity. Our simulation results on the Vimeo90 K dataset demonstrate that the proposed PENME method handles various types of video, outperforming traditional communication, hybrid, and adaptive bitrate semantic communication techniques, achieving 40% lower latency, 90% less transmitted data, and 35% higher throughput. For semantic communication metrics, PENME improves peak signal-to-noise ratio (PSNR) by about 40%, increases multi-scale structural similarity (MS-SSIM) by roughly 19%, and reduces learned perceptual image patch similarity (LPIPS) by nearly 35%, compared with the baseline methods.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"13 ","pages":"5385-5402"},"PeriodicalIF":7.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148511101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these methods suffer from limited data, which reduces both the detection accuracy and the model's generalization. Generative AI offers a novel solution to this issue, which can efficiently generate high-quality respiratory data, alleviate the problem of data scarcity and improve model performance. This study proposes an innovative approach that combines a diffusion model with a convolutional-transformer (CNN-Transformer) network model to achieve reliable recognition of respiratory patterns under data-scarce conditions. We first design a set of data preprocessing methods, which converts CSI amplitude and phase into 1D time series representing respiratory patterns. Then, we apply the diffusion model for data augmentation to generate diverse and high-quality RF data. Subsequently, the preprocessed data are mapped into 2D images using the gramian angular field (GAF) method and then fed into a CNN-Transformer network model to classify three types of respiratory patterns. Experimental results demonstrate that the proposed approach can effectively enhance the performance of respiratory pattern recognition. When combined with the CNN-Transformer model, the accuracy, precision, recall, and specificity are 98.3%, 98.3%, 98.0%, and 98.8%, respectively, which are improved by 3%-4% compared with the CNN, ResNet-18, and long short-term memory (LSTM) baseline models.

These networks must ensure reliable identity authentication while addressing privacy, efficiency, and security challenges. Traditional authentication mechanisms—such as PKI-based certificates and remote identification—either overexpose identity data or lack support for flexible attribute disclosure. Moreover, existing anonymous credential (AC) schemes, though offering privacy, often incur high computational and communication costs and exist vulnerable to replay attacks. To address these limitations, we propose <bold>DVA-ACLF</b> (<italic>Designated Verifier Asymmetric Anonymous Credential Scheme for Low-Altitude Flight</i>), a lightweight credential system tailored for AAVs.

Experimental results show that DVA-ACLF reduces credential size by 49% (2720 bits vs. 5369 bits in Idemix) and mitigates the linear growth of credential size with respect to attribute count observed in CL and BBS+ schemes.

As a result, RS transmission is no longer limited to the low Earth orbit (LEO) segment, and the optimization scope should be extended to the full VLEO–LEO process. However, full-process scheduling for multi-QoS RS services faces two major challenges. First, it is highly sensitive to environmental dynamics, since changes in network state may directly cause a group of services to shift from QoS-satisfied to QoS-violated. Second, multiple processes, including inter-layer topology formation, link latency mapping, and scheduling parameter adaptation, form a coupled decision chain that jointly determines the final scheduling result. This imposes strong demands on a system-level adaptive scheduling framework. To address these challenges, this paper proposes a Multi-dimensional Graph representation learning-driven Scheduling and Routing (MGSR) framework. MGSR adopts a hierarchical and collaborative Graph Representation Learning (GRL) architecture to enable system-level adaptive scheduling across multiple dimensions. It includes adaptive uplink node selection, spatiotemporal link latency mapping, and QoS-aware iterative scheduling into a unified decision process. By leveraging graph neural networks to capture topology evolution and traffic dynamics, MGSR can rapidly adjust routing and scheduling strategies under varying service ratios, traffic intensities, and constellation topologies. The simulations show that MGSR consistently outperforms state-of-the-art routing algorithms, achieving significant improvements in QoS satisfaction ratio.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"13 ","pages":"9413-9429"},"PeriodicalIF":7.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148513618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first establish an electromagnetic system model incorporating structural and antenna modes of the tags as well as clutter scatterers in the environment. By dynamically adjusting the load impedances of the tags, these structural and antenna mode components can be effectively separated. The structural and antenna mode components processed by the compressed sensing (CS) algorithms and the inverse scattering methods can respectively achieve high-precision localization of clutter scatterers and tags, as well as accurate identification of tags. In addition, channel state information (CSI) derived from antenna mode analysis during the localization and identification processes is utilized to seamlessly integrate SM and QSM techniques into the backscatter communication framework.
