Zihan Jia, Chen Chen, Alia Asheralieva, Lin Guan, Ziren Xiao	HAN: Adaptive DRL-based Congestion Control via Model Uncertainty	2026	Early Access	Modeling Algorithms Uncertainty	Congestion control (CC) algorithms are commonly categorized as rule-based, learning-based, and hybrid approaches. Rule-based methods such as Cubic and BBR provide predictable behavior and low overhead, but they often adapt poorly to dynamic or previously unseen network conditions. Deep reinforcement learning (DRL)-based CC algorithms can improve adaptability and average performance, yet they still suffer from limited generalization, unsafe exploration, instability, and long-tail latency in unfamiliar environments. Hybrid designs attempt to combine the strengths of both families by guiding DRL agents with expert policies. However, training-time expert guidance can restrict exploration, impose a performance ceiling, and, in some designs, unintentionally reward fallback-triggering actions. We propose HAN (Hybrid with Adaptive Uncertainty-based Navigation), a hybrid CC framework that switches between a learned DRL policy and a traditional CC algorithm according to model uncertainty at inference time. Rather than constraining the learning process with expert rules, HAN estimates the confidence of DRL decisions and selectively defers to a traditional CC algorithm when uncertainty is high. This uncertainty-aware mechanism preserves the adaptability of DRL while improving stability and robustness across diverse network scenarios. We compare HAN with state-of-the-art CC algorithms under varying bandwidth, buffer size, random loss, and heterogeneous network environments. Empirical results show that HAN achieves up to 83% higher throughput and reduces average latency by 36% compared with existing CC methods. These findings highlight the potential of uncertainty-aware decision-making for future CC algorithm design.	10.1109/TNSM.2026.3711195
Florian Wiedner, Alexander Daichendt, Jonas Andre, Georg Carle	Utilizing Hardware-Supported Containers for Low-Latency Networking	2026	Early Access	Containers Fluid flow Kernel	Applications requiring low-latency packet processing are challenging for today’s network and service management when resources are limited and must be shared. Containers are suitable, but achieving connectivity between containers exclusively in software is unsuitable for low-latency requirements. The impact of network latencies in containerized environments has received comparatively less attention, particularly in comparison to research on virtual machines. This paper analyzes throughput and network latencies in container-based networks on a single host featuring single-root input/output virtualization, Linux Containers, and commercial off-the-shelf hardware. We conduct measurements using a state-of-the-art measurement methodology to identify tail-latency behavior, achieving a resolution of 1.25 μs. We evaluate a single flow in a line topology with up to 64 containers and a complex topology with 38 flows and 12 container nodes. The experiments demonstrate that pinning interrupt request handlers to non-uniform memory access nodes increases throughput and decreases latencies. Furthermore, we identify data translation lookaside buffer misses, rescheduling interrupts, and soft interrupt floods as critical challenges causing spikes in latencies while isolation remains impossible. Our findings identify bottlenecks for real-time container applications. A comparison with VM measurements shows that containers can achieve latencies up to 60 μs lower. We support in this paper, network and service management in deciding on the underlying virtualization technology for packet-processing applications by providing recommendations accordingly.	10.1109/TNSM.2026.3711934
Shi-Xin Huang, Te-Chuan Chiu, Jing-Chih Lin, Cheng-Hsuan Kuo	EdgeCookie: A Mitigation Solution Against Threatening TCP DDoS Attack in Edge Cloud	2026	Early Access	Servers Switches TCP	With the explosive growth of GenAI service requirements, the demand for digital infrastructure and cloud resources continues to increase. At the same time, distributed denial-of-service (DDoS) attacks – particularly TCP-based vectors such as SYN flood and emerging TCP distributed reflective denial-of-service (DRDoS) – have surged, posing a significant threat to service availability. Current mitigation strategies often fall short in effectively countering both attack types. Although the proliferation of edge computing offers opportunities to deploy mitigation closer to attack sources, it also introduces synchronization challenges across distributed edge servers. In this paper, we propose EdgeCookie, an edge-centric TCP flood attack mitigation architecture. EdgeCookie can mitigate TCP SYN floods, ACK floods, and emerging TCP reflection amplification attacks. Unlike existing switch-based defenses, EdgeCookie requires no specific hardware, making it suitable for running in resource-limited edge clouds. In the core mechanism, we introduce a novel HybridCookie that effectively solves synchronization challenges across distributed edge servers. Experimental results demonstrate that EdgeCookie can mitigate both TCP SYN flood and emerging TCP reflection amplification attacks without facing false positive issues, while maintaining high throughput and adding negligible latency to legitimate traffic.	10.1109/TNSM.2026.3706627
Masoumeh Safkhani, Mohammad Reza Servati, Fatemeh Rezaei	HEIoT: A Novel Three-Factor Authentication Protocol for Enhanced Security in IoT and Next-Generation Networks	2026	Early Access	Authentication Internet of Things Protocols	The Internet has a significant impact on contemporary society, enabling a wide range of applications, including advanced cellular networks such as 4G, 5G, and 6G. Since these communications occur over shared or open channels, ensuring secure data exchange is of critical importance, as any weakness in the communication infrastructure may compromise system reliability. Device authentication in the Internet of Things (IoT) and user authentication in smart environments, such as smart homes, remain fundamental security challenges. As the first line of defense, authentication mechanisms must be robust, since vulnerabilities at this stage can expose the entire system to serious threats. To address these challenges, numerous authentication schemes based on cryptographic primitives, including Elliptic Curve Cryptography (ECC), have been proposed. In this paper, we present a comprehensive security analysis of an ECC-based three-factor authentication protocol proposed by Yuan et al. Our analysis shows that the protocol is vulnerable to desynchronization, user impersonation, traceability, and insider attacks, all of which succeed with probability 1 by exploiting at most two protocol phases. To mitigate these weaknesses, we propose an improved authentication scheme, called HEIoT. The proposed scheme is formally analyzed under the Real-or-Random (RoR) model to establish session-key security and is further verified using the Scyther tool. Moreover, a Python-based implementation is provided to demonstrate the practicality of the proposed protocol. Comparative results indicate that HEIoT achieves stronger security while maintaining acceptable communication, computational, and storage overhead.	10.1109/TNSM.2026.3702041
Jing Zhang, Chao Luo, Rui Shao	MTG-GAN: A Masked Temporal Graph Generative Adversarial Network for Cross-Domain System Log Anomaly Detection	2026	Early Access	Anomaly detection Adaptation models Generative adversarial networks	Anomaly detection of system logs is crucial for the service management of large-scale information systems. Nowadays, log anomaly detection faces two main challenges: 1) capturing evolving temporal dependencies between log events to adaptively tackle with emerging anomaly patterns, 2) and maintaining high detection capabilities across varies data distributions. Existing methods rely heavily on domain-specific data features, making it challenging to handle the heterogeneity and temporal dynamics of log data. This limitation restricts the deployment of anomaly detection systems in practical environments. In this article, a novel framework, Masked Temporal Graph Generative Adversarial Network (MTG-GAN), is proposed for both conventional and cross-domain log anomaly detection. The model enhances the detection capability for emerging abnormal patterns in system log data by introducing an adaptive masking mechanism that combines generative adversarial networks with graph contrastive learning. Additionally, MTG-GAN reduces dependency on specific data distribution and improves model generalization by using diffused graph adjacency information deriving from temporal relevance of event sequence, which can be conducive to improve cross-domain detection performance. Experimental results demonstrate that MTG-GAN outperforms existing methods on multiple real-world datasets in both conventional and cross-domain log anomaly detection.	10.1109/TNSM.2026.3654642
Shuang Zheng, Xing Zhang, Michael Sheng, Haixu Wang, Wenbo Wang	Beam Hopping Low Earth Orbit Satellite Resource Allocation for Differentiated Services and Robustness Analysis under Model Attacks	2026	Early Access	Beams Satellites Resource management	Beam hopping (BH)-enabled Low Earth Orbit (LEO) satellites play a pivotal role in next-generation communication networks, providing global coverage, improving spectrum efficiency, and supporting flexible adaptation to heterogeneous service demands. To fully exploit these capabilities, artificial intelligence (AI) techniques are increasingly employed for dynamic resource allocation and power management. However, limited onboard resources and potential adversarial perturbations pose challenges to both efficiency and robustness. To address these issues, we leverage digital twin technology to accurately capture the spatio-temporal dynamics of user–satellite visibility, providing precise state information for decision-making. Building on this, we formulate a joint optimization framework for BH scheduling and power allocation as a Markov Decision Process and propose the BRIDGE—BH with Reinforcement learning incorporating Integrated Dirichlet and Gumbel-TopK Exploration—which integrates a quality of service (QoS)-driven subchannel scheduling mechanism to ensure efficient and differentiated resource allocation. The model’s robustness is systematically evaluated under three classical adversarial attacks. Simulation results demonstrate that our approach achieves superior energy efficiency, service throughput, and fairness, while the robustness analysis shows stable performance under the considered bounded adversarial perturbations.	10.1109/TNSM.2026.3710750
Zhizhou He, Mohammad Shojafar, Rahim Tafazolli	Service-oriented Attention HAPPO for xApps Coordination in Digital Twin Enabled AI-RAN	2026	Early Access	Modeling Open RAN Training	Coordinating multiple heterogeneous xApps in Open Radio Access Networks (O-RAN) is challenging because real-time inter-xApp synchronization introduces communication overhead, latency, and scalability bottlenecks under live deployments. This paper proposes an attention-based Heterogeneous-Agent Proximal Policy Optimization (HAPPO) framework that coordinates four heterogeneous xApps—power control, resource-block allocation, access control, and beam selection—through a Digital Twin (DT)-enabled training pipeline. The framework combines (i) hybrid actor heads supporting mixed continuous/discrete actions, (ii) task-aware self-attention for implicit coordination without predefined communication graphs, and (iii) DT-based asynchronous experience collection with delay modelling, online correction, and safe rollback. We further validate that the learned attention aligns with the physical coupling between xApps (Pearson ρ = 0.78±0.04), establishing an interpretable link between the policy and underlying network dependencies. On a VIAVI O-RAN RIC emulator across 10 random seeds, the proposed scheme attains a 91.2% aggregate QoS score and 1.05 ms inference latency, improves per-slice SLA satisfaction by up to 6.4% over strong MARL baselines (FACMAC, MAPPO, CommNet), and reaches the 80%-of-final performance level 1.49× faster than the attention-free counter-part. Improvements are statistically significant (p < 0.05, paired two-sided Welch t-tests with Holm–Bonferroni correction across baselines; under fluctuating UE demands and diverse service-level requirements).	10.1109/TNSM.2026.3710685
Madhura Adeppady, Yenchia Yu, Ali Rahmanian, Ahmed Ali-Eldin Hassan, Carla Fabiana Chiasserini	Efficient Management of Composite Heterogeneous Applications at the Network Edge	2026	Early Access	Central Processing Unit Servers Resource management	Edge computing is a promising paradigm for deploying latency-sensitive applications (Apps) as it brings resources closer to end users. Edge Apps often adopt a microservice (MS) architecture, breaking monolithic Apps into lightweight, containerized MSs that can be dynamically and independently deployed. However, managing such Apps involves three key challenges: (i) optimizing the placement of MSs to reduce both response time and resource overhead, (ii) handling MS migration or relocation as users move while minimizing App service disruption (App downtime), and (iii) enabling MS sharing across Apps while ensuring performance guarantees. We formulate this as an optimization problem, named Multi-microservice Application Placement (MAP), prove its NP-hardness, and introduce STEP (State and Topology-aware Edge-MS Placement), a polynomial-time heuristic. STEP distinguishes itself from prior work by: (i) jointly considering stateful and stateless MS characteristics in deployment decisions, (ii) exploiting MS shareability to reduce resource usage, (iii) balancing response latency, App downtime, and resource utilization, and (iv) leveraging multiple versions of the same MS to adapt quality of service to available edge resources. Our results in a small-scale scenario show that STEP achieves near-optimal performance with only 7% higher CPU cost than the optimal solution. Large-scale real-time experiments on a Kubernetes cluster demonstrate that STEP consistently outperforms competing methods, achieving up to 50% lower deployment costs while delivering 50% gain in app quality and saving 15% in radio resources with over 90% request success rates.	10.1109/TNSM.2026.3709656
Yongqiang Dong, Jiangnan Sun, Jiawen Li, Yongbo Liu	Learning to Configure Like Engineers: Manual Guided Network Configuration Sketch Generation	2026	Early Access	Modeling Syntactics Large language models	Network configuration automation is a key component of intelligent network operations aiming to transform user intents into executable device configurations. Most existing approaches take a paradigm of parameter filling within predefined sketches, where the sketches have to be crafted manually by engineers and user intents are expressed in a specific format. Other studies follow a routine of synthesizing configurations directly from natural-language intents, taking advantage of large language models (LLMs) and retrieval augmented generation techniques. The results are yet far from satisfactory in practice due to the complexity of the network configuration requirements. A recently proposed example-driven configuration synthesis method (CEGS), attempts to learn from configuration examples provided by vendors. However, its effectiveness is bounded by example coverage, and the method struggles to generalize to new scenarios. To address this, we present LCLE, an end-to-end sketch generation framework that learns how to configure networks from device configuration guides and command references, much as human engineers do. Specifically, LCLE automatically generates configuration sketches from natural-language intents by LLMs with a structured device configuration model (DCM) extracted from vendor manuals. The DCM organizes configuration workflows, command syntax, and view hierarchies into a unified knowledge base that supports LCLE’s retrieval-augmented generation through a three-stage pipeline of intent parsing, sketch generation, and sketch optimization. Extensive experiments on Huawei and Cisco devices show that LCLE significantly improves the semantic completeness and syntactic correctness of the generated configuration sketches. In addition, the framework can be easily extended to new devices and protocols through DCM updates, promising a scalable solution for automated network configuration.	10.1109/TNSM.2026.3710600
Chenchen Xu, Fulong Chen, Darong Huang, Hongchao Li, Xin Hong, Taochun Wang	RDTSM: Robust Defense Based on Trusted Shadow Model Against Poisoning Attacks for Federated Learning	2026	Early Access	Modeling Shadow mapping Federated learning	Federated learning enables collaborative model training without sharing raw data, but remains vulnerable to poisoning attacks from malicious clients. These adversarial participants craft harmful updates to degrade global model performance or induce targeted misclassification. Without trusted reference gradients, the central model cannot be properly aggregated only based on updates provided by untrustworthy clients. In this paper, we propose RDTSM, a robust defense method based on a trusted shadow model. By leveraging a clean shadow dataset, the central server generates reference updates and evaluates each client’s update via a reputation scoring mechanism. A clustering algorithm is then applied to identify and exclude suspicious updates before model aggregation. Extensive experiments on MNIST, Fashion-MNIST, and CIFAR-10 demonstrate that RDTSM consistently outperforms state-of-the- art defenses across a wide range of poisoning attacks. Notably, RDTSM maintains high accuracy even when the proportion of malicious clients is large, and remains robust under varying degrees of data heterogeneity and shadow dataset sizes. This robustness stems from the fact that shadow-guided reputation scores of benign and malicious clients remain well separated under homogeneous attack patterns, even when malicious clients constitute the majority. These results show RDTSM’s effectiveness and practicality for secure federated learning in adversarial environments.	10.1109/TNSM.2026.3710818
Xiwen Liao, Supeng Leng, Ke Zhang, Yao Sun, Muhammad Ali Imran	Spatiotemporal Resource Orchestration for LLM Inference in Vehicular-Edge Networks	2026	Early Access	Modeling Large language models Vehicles	Large Language Models (LLMs) have been increasingly applied to intelligent vehicular systems for tasks such as scene understanding, intent reasoning, and natural language interaction. However, their inference demands exceed onboard processing capabilities, making low-latency on-vehicle inference impractical. Although edge computing can partially offload computation, the prolonged nature of LLM inference often causes execution to exceed the residence time of vehicles within edge coverage areas, leading to frequent service interruption. To address these challenges, we propose a collaborative spatiotemporal resource orchestration architecture for LLM inference in vehicular-edge networks (CoInfer). CoInfer exploits the intrinsic decomposability of LLM inference by modeling each request as a Directed Acyclic Graph (DAG) of interdependent subtasks, which are then scheduled, migrated, and aggregated along the road network to preserve end-to-end inference continuity. To improve latency and resource efficiency, CoInfer integrates multi-agent reinforcement learning for coarse-grained task orchestration with a reactive scheduler for fine-grained resource adaptation, forming a closed-loop service optimization under dynamic resource conditions. The simulation results demonstrate that CoInfer achieves a task success ratio of up to 96.0% and reduces the end-to-end inference latency by 35.7% compared to representative baselines.	10.1109/TNSM.2026.3710972
David Segura, Emil J. Khatib, Raquel Barco	Evaluation of Mobile Network Slicing in a Logistics Distribution Center	2026	Early Access	5G mobile communication Massive machine type communications Timing	Logistics is a key economic sector where any optimization that reduces costs or improves service has a great impact on society at large. Network Slicing (NS) is a technique that allows the creation of different independent networks with different dedicated resources on a shared physical infrastructure. This is particularly useful in scenarios where different applications with different requirements coexist. In this paper, an open-source simulator based on NS-3 with several implemented extensions has been developed, with a realistic representation of a distribution center scenario, including the logistics activities that take place there. Under this developed simulator, the role of two 5G NS strategies in Smart Logistics is studied: the use of a static balanced division and the use of a dynamic allocation of resources between slices. These strategies have been evaluated in terms of Quality of Service (QoS) for different traffic profiles via simulations. Results show that a dynamic slice allocation makes a more efficient usage of the network resources, improving the QoS for the different traffic profiles, even when there is a traffic peak. This improvement ranges from 6.48% to 95.65%, depending on the specific traffic profile and the evaluated metric.	10.1109/TNSM.2026.3712270
Rania Farjallah, Bassant Selim, Brigitte Jaumard, Samr Ali, Georges Kaddoum, Jean-Michel Sellier	Maximum Entropy-Based Traffic Generation	2026	Early Access	Modeling Optimization Entropy	The development of machine learning models and algorithms for many communication network optimization problems has generated a huge need for realistic traffic data generators, as real-world traffic datasets remain very few, especially compared to their size. We therefore propose a novel traffic generation framework based on the Maximum Entropy Principle (MEP). It explicitly incorporates empirical statistical constraints, ensuring generated traffic closely mirrors the complex patterns found in real-world data. Using vehicle traffic datasets of the City of Calgary, we explore multiple distributional assumptions, namely Gaussian, exponential, and mixture models. Our results demonstrate that the Gaussian and the Gaussian mixture models consistently achieve superior performance, capturing diverse temporal fluctuations and intricate statistical behaviors inherent in urban vehicle traffic. This study not only highlights the effectiveness and flexibility of MEP-based models but also establishes them as robust, interpretable, and data-efficient alternatives to existing generative methods in traffic synthesis.	10.1109/TNSM.2026.3712637
Dev Gurung, Shiva Raj Pokhrel	LLM-QFL: Distilling Large Language Model for Quantum Federated Learning	2026	Early Access	Modeling Federated learning Large language models	As Quantum Federated Learning (QFL) scales toward distributed quantum networks, managing heterogeneous resources and communication bottlenecks becomes a critical challenge. This research proposes LLM-QFL, an adaptive network service management framework that leverages Large Language Models (LLMs) to optimize the operational efficiency of QFL systems. We introduce a federated distillation method in which locally fine-tuned LLMs serve as autonomous network agents. These agents adaptively manage service parameters by: i) dynamically adjusting local computation intensity (optimizer steps) based on loss gradients, ii) performing variance-aware client selection to minimize network-wide heterogeneity, and iii) implementing intelligent early stopping criteria to conserve bandwidth. By serving as an orchestration layer, LLM-QFL provides a synergy between LLMs and quantum networking. Our contributions include: i) Adaptive Performance and Efficiency: Reducing idle computation and significantly cutting communication overhead; ii) Theoretical Rigor: Convergence guarantees of O(1/T) for the adaptive management protocol; and iii) Scalable Deployment: Implementing PEFT (LoRA/QLoRA) for resource-constrained quantum service nodes.	10.1109/TNSM.2026.3712394
Deemah H. Tashman, Soumaya Cherkaoui	Trustworthy AI-Driven Dynamic Hybrid RIS: Joint Optimization and Reward Poisoning-Resilient Control in Cognitive MISO Networks	2026	Early Access	Reconfigurable intelligent surfaces Reliability Optimization	Cognitive radio networks (CRNs) are a key mechanism for alleviating spectrum scarcity by enabling secondary users (SUs) to opportunistically access licensed frequency bands without harmful interference to primary users (PUs). To address unreliable direct SU links and energy constraints common in next-generation wireless networks, this work introduces an adaptive, energy-aware hybrid reconfigurable intelligent surface (RIS) for underlay multiple-input single-output (MISO) CRNs. Distinct from prior approaches relying on static RIS architectures, our proposed RIS dynamically alternates between passive and active operation modes in real time according to harvested energy availability. We also model our scenario under practical hardware impairments and cascaded fading channels. We formulate and solve a joint transmit beamforming and RIS phase optimization problem via the soft actor-critic (SAC) deep reinforcement learning (DRL) method, leveraging its robustness in continuous and highly dynamic environments. Notably, we conduct the first systematic study of reward poisoning attacks on DRL agents in RIS-enhanced CRNs, and propose a lightweight, real-time defense based on reward clipping and statistical anomaly filtering. Numerical results demonstrate that the SAC-based approach consistently outperforms established DRL base-lines, and that the dynamic hybrid RIS strikes a superior trade-off between throughput and energy consumption compared to fully passive and fully active alternatives. We further show the effectiveness of our defense in maintaining SU performance even under adversarial conditions. Our results advance the practical and secure deployment of RIS-assisted CRNs, and highlight crucial design insights for energy-constrained wireless systems.	10.1109/TNSM.2026.3660728
Lion Steger, Liming Kuang, Johannes Zirngibl, Georg Carle, Oliver Gasser	Still on Target? An Evaluation of IPv6 Target Generation Algorithms	2026	Early Access		Internet measurements are a crucial foundation of IPv6-related research. Due to the infeasibility of full address space scans for IPv6 however, those measurements rely on collections of reliably responsive, unbiased addresses, as provided e.g., by the IPv6 Hitlist service. Although used for various use cases, the hitlist provides an unfiltered list of responsive addresses, the hosts behind which can come from a range of different networks and devices, such as web servers, customer-premises equipment (CPE) devices, and Internet infrastructure. In this paper, we demonstrate the importance of tailoring hitlists in accordance with the research goal in question. By using PeeringDB we classify hitlist addresses into six different network categories, uncovering that 42% of hitlist addresses are in ISP networks. Moreover, we show the different behavior of those addresses depending on their respective category, e.g., ISP addresses exhibiting a relatively low lifetime. Furthermore, we analyze different Target Generation Algorithms (TGAs), which are used to increase the coverage of IPv6 measurements by generating new responsive targets for scans. We use seed sets, e.g., based on the categorized Hitlist. We evaluate the performance of TGAs under various conditions and find generated addresses to show vastly differing responsiveness levels for different TGAs. Furthermore, we evaluate of algorithm run times and differences between multiple TGA runs.	10.1109/TNSM.2026.3705935
David Kule Mukuhi, Leo Mendiboure, Rami Langar, Rodrigue Fargeon, Sylvain Cherrier, Marion Berbineau, Pierre-Yves Petton	Application-aware Slicing for FRMCS: A Deep Reinforcement Learning Approach	2026	Early Access		The Future Railway Mobile Communication System (FRMCS) will replace GSM-R to support safety-critical and high-throughput applications over a limited 5–10 MHz spectrum. Railway services range from ultra-reliable train control, such as European Train Control System and Automatic Train Operation, to bandwidth-intensive video surveillance and best-effort passenger Wi-Fi, each with distinct requirements. Existing network slicing solutions designed for public 5G networks focus on aggregate slice-level guarantees, neglecting heterogeneous application requirements and the strong channel fluctuations induced by high-speed train mobility. To overcome this limitation, we propose in this paper an Application-Driven Slice Scheduling (ADSS) approach tailored for railway communications. ADSS leverages Deep Reinforcement Learning combined with channel-aware resource allocation to dynamically assign Resource Blocks, ensuring application-level Service Level Agreement (SLA) fulfillment. Evaluations on real Signal-to-Noise Ratio traces from trains traveling at speeds up to 350 km/h, demonstrate that ADSS achieves superior application-level SLA satisfaction, reduces violation gaps, and improves spectral efficiency compared to heuristic and state-of-the-art schedulers.	10.1109/TNSM.2026.3710830
Liang Chen, Xiaoding Wang, Limei Lin, Yanze Huang, Siwei Zheng	Defense in Depth: Architectural Homology for Adversarially Robust Semantic Communication	2026	Early Access		Semantic communication framework based on deep encoder–decoder architectures are increasingly vulnerable to adversarial attacks, wherein imperceptible input perturbations can induce significant misclassifications, posing critical risks to next-generation communication networks. To address this challenge, we introduce TopAliSC-KG, a holistic robust learning framework designed to fortify semantic communication against adversarial threats through a multi-layered defense strategy. Our approach integrates two complementary mechanisms: a homology graph-aligned adversarial training module that embeds topological constraints into the model optimization process to promote structural invariance, and a knowledge-guided semantic consistency module that utilizes auxiliary models to inject stable, high-level semantic information into the training loop. Together, these components establish a defense-in-depth architecture that enhances resilience across data, feature, and model levels. Extensive evaluations across diverse channel conditions, signal-to-noise ratios, and adversarial attack scenarios show that TopAliSC-KG consistently improves adversarial accuracy by 0.32%–3.39%, with the knowledge guidance mechanism contributing a further 0.11%–0.21% gain. This work provides a validated, multi-framework defense strategy suitable for securing semantic communication in mission-critical applications, advancing both the security and reliability of intelligent communication systems.	10.1109/TNSM.2026.3705940
Behrooz Farkiani, Fan Liu, Ke Yang, John DeHart, Jyoti Parwatikar, Patrick Crowley	Hermes: A General-Purpose Proxy-Enabled Networking Architecture	2026	Early Access	Tunneling HTTP Joining processes	We introduce Hermes, a general-purpose networking architecture that aims to improve service delivery over the Internet. Hermes delegates networking responsibilities from applications and services to proxies and is designed as a portable, adaptable solution to four fundamental challenges of efficient service delivery over the Internet: end-to-end traffic management, backward compatibility, data-plane security and privacy models, and adaptable communication layers. The design centers on an overlay of reconfigurable proxies and HTTP tunneling and proxying techniques, utilizing assisting components to extend proxy functionality when needed. Through prototyping and emulation, we demonstrate that Hermes improves key performance metrics across multiple use cases: it provides backward compatibility through protocol translation and tunneling, improves reliability by delegating retry logic to proxies, enables unified policy-based Layer 3 routing across network segments, and serves as an efficient substrate for future architectures like NDN, facilitating their operation over the Internet. Beyond evaluating Hermes across various use cases, we measured the overhead of Hermes’ HTTP tunneling and proxying mechanisms and found it to be modest, typically under 2 ms per proxy pair traversal in an isolated collocated setup. Although the HTTP proxying and tunneling techniques used by Hermes increase single-connection processing overhead, we also show that, with up to 1,000 concurrent requests, proxies can amortize connection setup time and reduce end-to-end latency by utilizing connection pooling and multiplexing.	10.1109/TNSM.2026.3705327
Soonbeom Kwon, Yusu Noh, Youngwoo Jang, Illyoung Choi, Byungchul Tak, In-geol Chun, Young-Kyoon Suh	Scalable and Robust Resource Provisioning via Adaptive Task Scheduling for Edge Devices	2026	Early Access	Schedules Scheduling Cloning	Edge devices, such as wearables, drones, and CCTV systems, are vital for real-time data collection in urban intelligence. However, their limited computational and storage capacities pose significant challenges. While offloading to public clouds offers scalability, it often incurs high latency and operational costs. Conversely, centralizing workloads on edge servers may result in the underutilization of high-performance edge devices. To address these limitations, we introduce ERPF, a Kubernetes-based Edge Resource Provisioning Framework that augments the capabilities of heterogeneous edge environments. ERPF orchestrates dynamic volume provisioning, GPU-aware resource allocation, execution context migration, and adaptive task distribution to improve system flexibility and efficiency. Building on this, we propose a novel adaptive task scheduling technique, termed eATS, composed of three key mechanisms: (i) Partition Smoothing Scheme for stable task granularity control, (ii) Resilient Edge Reintegration for failure detection and task reassignment, and (iii) Competitive Task Cloning for speculative execution with fastest-result commitment. The proposed eATS scheme reduces task execution time by up to 27.6%, lowers partition size variability by 8.7×, and improves scheduling robustness across heterogeneous edge devices over the baseline.	10.1109/TNSM.2026.3694238
