Although Computing Power Network (CPN) as the new network computing paradigm which can fully improve the utilization rate of decentralized computing power resources, the dynamic and heterogeneous characteristics of multivariate workloads present significant challenges to maintaining the Quality of Service (QoS) under dynamic resource scheduling. Therefore, workload prediction should be considered to ensure elastic demand services. However, the existing workload prediction methods mainly focus on (1) a single-granularity perspective, and (2) struggle to adapt to dynamic and heterogeneous multivariate workload environments, such as traditional LSTM-based or CNN-based methods that fail to capture cross-granularity dependencies under varying workload patterns. To consider above problems, we propose Multi-Granularity Workload Ensemble and Feature Inference for Multivariate Computing Power Prediction (MG-WEP), which address the problem from a multi-granularity perspective. First, we develop a mutual information feature selection method using a variational inference network to identify key features, facilitating a comprehensive exploration of the relationships among workload variables from an attribute perspective. Then, the clustering method is used to cluster similar workloads, effectively capturing the relationships among them. Furthermore, a combined ensemble prediction method is applied on all clustered workloads to improve prediction accuracy by leveraging the distinctive characteristics of each cluster from object perspective. Finally, we have fully compared the proposed algorithm with eleven comparison methods and four evaluation metrics on three real-world workload trace datasets. The results show that the proposed method has superior prediction performance.

Large-scale distributed wireless networks provide infrastructure-free and cost-effective connectivity, supporting applications from disaster recovery to global digital inclusion. However, multi-hop communication introduces scalability challenges, as point-to-point (P2P) capacity decreases with the number of intermediate relays (hop count). The growth rate of the expected hop count with network expansion is primarily governed by the underlying interaction patterns among network users. Thus, this study focuses on the critical role of multi-hop communication and user interaction probability, which empirical evidence shows it decays as a power law with geographic distance. We present a comprehensive analysis of network scalability, from capacity estimation to empirical evaluation of real-world interaction patterns. The capacity estimation problem is decomposed using a novel analytical methodology, along with symmetric topology selection and geometric partitioning, to overcome the complexities inherent in previous models. The estimated P2P capacity bounds, derived from expected hop count, surpass previous benchmarks. Specifically, when the power-law exponent exceeds a critical threshold, the expected hop count remains stable and P2P capacity is sustained; otherwise, the hop count grows and capacity declines as the network scales. Accordingly, an analytical method is devised to relate real-world interaction patterns to the power-law exponent, quantified by the contact distribution. The analysis of multiple empirical datasets confirms that the exponent falls within a range that naturally supports scalability. Consequently, multi-hop communication does not fundamentally hinder the wide-scale deployment of distributed wireless networks. This capacity-based analysis provides a clear perspective on scalability under realistic interaction patterns and underscores the promising future of such networks, as well as their potential for widespread deployment.

In federated learning, improving communication efficiency is a critical challenge, especially under partial participation and biased compression. Many existing approaches rely on unbiased compression or strong assumptions, such as the bounded gradient assumption, which are often difficult to satisfy in practice. In this paper, we propose a novel federated learning algorithm named EF21-MP (EF21 with Momentum and Partial Participation), which combines biased compression with partial participation and stochastic gradient descent. Furthermore, it incorporates momentum and EF21 to reduce variance from stochastic gradient descent and biased compression. It achieves convergence for nonconvex optimization under standard smoothness and bounded variance conditions, without relying on any bounded gradient assumptions, and could support for batch-free training. The numerical results demonstrate that EF21-MP consistently outperforms the existing baselines.
在联邦学习中，提高通信效率是一个关键的挑战，特别是在部分参与和偏压缩的情况下。许多现有的方法依赖于无偏压缩或强假设，如有界梯度假设，这些假设在实践中往往难以满足。在本文中，我们提出了一种新的联合学习算法EF21- mp (EF21 with Momentum and Partial Participation)，它结合了偏压、偏参与和随机梯度下降。此外，该方法还结合了动量和EF21来减小随机梯度下降和偏压带来的方差。它在标准平滑和有界方差条件下实现了非凸优化的收敛性，不依赖于任何有界梯度假设，可以支持无批处理训练。数值结果表明，EF21-MP始终优于现有基线。

With the rapid development of the Electric Vehicle (EV) market, the growing demand for electricity charging has driven the evolution of private charging infrastructure toward shared deployment. Shared Charging Systems (SCSs) play a vital role in integrating both private and public Charging Piles (CPs), thereby improving overall resource utilization. However, such multi-party SCSs introduce challenges in security and fairness. EVs and CPs exchange parameters via wireless communication to optimize the charging process, which may exposes various threats such as tampering, eavesdropping, replay, and deletion attacks. Meanwhile, the distributed deployment of CPs complicates charging fee calculation management and may lead to issues such as malicious overcharging. To address these challenges, we propose a blockchain-enabled secure authentication and fair trading scheme, ensuring secure communication while guaranteeing transparency and fairness for SCSs. First, we design a pairing-free heterogeneous signcryption algorithm that supports distributed key generation. It realizes efficient mutual authentication based on this algorithm while preventing information leakage during the process. We provide a rigorous security proof under the Random Oracle Model (ROM) to establish its security. Second, we develop a blockchain-based smart contract mechanism to enable decentralized and transparent charging fee calculation, as well as automated payments. By eliminating third-party intermediaries, our solution reduces trading costs whle effectively addresses challenges such as charging fee calculation difficulties and malicious overcharging in distributed CP deployments. Experimental results show that the proposed scheme outperforms existing approaches in terms of both computational and communication overhead. Additionally, our smart contracts incur extremely low gas costs, enhancing the feasibility of the scheme.

In social networks, the accurate detection of guided topics is of great significance for maintaining the healthy order of the network. Aiming at the high-dimensionality of its feature space and the hiddenness of users' emotions, a guided topic detection method based on data enhancement and feature representation is proposed. Firstly, to address the problem of sparse effective data and high-dimensional heterogeneity in the early stage of guided topic, GAN network is introduced to realize homomorphic compensation of data and enhance data diversity. Meanwhile, the SC2vec method is designed to realize the low-rank densification of data. In addition, random wandering is introduced to mine the implicit association network among users and to realize the fusion of multi-dimensional information. Secondly, to address the problem of the hidden nature of users' emotional polarity, the internal attributes and external influences of users are mined. The fine-grained emotional influence factors based on linear multiple regression are constructed. At the same time, the evolutionary game theory is introduced to build an emotional interaction game model between users to reveal the dynamic evolution law of users' emotions. The experimental results show that the method not only successfully realizes the low-rank densification of data and the deep mining of implicit user emotions, but also achieves significant improvement in the accuracy of guided topic detection.

Community detection is capable of uncovering the inherent structure and functional organization within complex networks by analyzing multi-scale topological features. According to the brief survey, local detection methods demonstrate notable strengths, but challenges persist in selecting suitable seeds, identifying community cores, and precisely extending communities. Therefore, in this paper, a local community detection algorithm based on identifying high-quality core region is proposed. Specifically, at the seed selection stage, a core cohesiveness index is constructed to quantify the node importance, with two-step filtering strategy implemented to refine the selection of suitable seeds. After that, a hierarchical affinity evaluation mechanism is proposed on the basis of node-core affinity values to ensure the formation of high-quality core region (i.e., high-quality initial community). Community extension is then achieved by using the enhanced objective function combined with an incremental update strategy, it preserves structural cohesion and reduces computational costs. Finally, the membership assignments of the remaining nodes will be further processed through community optimization to refine community boundaries. Experimental results demonstrate that our proposed algorithm outperforms other community detection algorithms with relatively low time complexities across multi-scale real-world and synthetic networks.

Space-Air-Ground Integrated Networks (SAGIN) have been recognized as key enablers of 6G systems for ubiquitous service provisioning, unlocking Internet of Things (IoT) applications in geographically dispersed areas. In this paper, we study the problem of computation task offloading for remotely deployed IoT devices to either a limited-capability Uncrewed Aerial Vehicle (UAV)-mounted Multi-access Edge Computing (MEC) server or a cloud server via satellite relaying. The problem is formulated as a non-cooperative game, where each IoT device autonomously determines the percentage of task offloaded to each server to minimize the aggregate time and energy overhead due to transmissions and remote processing. Diverging from the prevailing literature, in this paper, we model the IoT devices' risk-seeking and loss-averse behavior in sharing the common pools of computing resources, i.e., cloud and MEC server. By incorporating risk-consciousness in their computation offloading decision-making, IoT devices strive to balance the total incurred overhead with the likelihood of task rejection due to overexploitation of limited shared edge resources. To this end, the IoT devices' utility function is modeled using Prospect Theory and Tragedy of the Commons. Two solutions based on normal and satisfaction-form games are derived, targeting to maximize or achieve a minimum value for the prospect-theoretic utility, providing insights from both device and system perspectives, respectively. Numerical results show the effectiveness of the overall risk-conscious computing framework in the achieved time and energy overhead, as well as task probability of failure.

Rate-splitting multiple access (RSMA) and successive interference cancellation (SIC) are essential approaches in the next-generation communication systems that boost spectrum efficiency by effectively managing and mitigating interference between multiple signals. However, a challenge arises in ensuring that users can distinguish the common message from the remaining non-decoded private messages without considering a separate SIC constraint per user. This imperfection cancellation leads to residual interference from the common stream that remains in the received signal. This work investigates the maximization of the weighted sum-rate (WSR) in single-layer RSMA multiple input single output (MISO) downlink network by proposing explicit SIC constraints. In particular, we suggest an approach that initially addresses the critical problem of allocating power and precoding vectors for streams using a deep reinforcement learning (DRL) method, and then determines the user-specific allocations within the common rate to meet the criteria of users’ minimum rate by solving a linear programming problem. Simulation results exhibit the supremacy of the proposed DRL framework over SDMA and other DRL approaches in terms of spectral efficiency leading to an improvement of approximately 30% of WSR in several scenarios.

With the deep evolution of satellite communication technologies and hierarchical hybrid networks (HHSNs), modern communication satellites have transformed from single-function relay nodes into core hubs enabling global interconnectivity. The dynamic topology, open-channel environment, and resource limitations inherent to HHSN expose satellite routing protocols to the challenges of the Reliability-Security-Efficiency (RSE) trilemma. In this paper, we provide a systematic review of advancements in HHSN routing research, analyzing core technical challenges through the lens of typical application scenarios while highlighting the divergent performance of various solutions under the RSE trilemma. To the best of our knowledge, we are the first to analyze the performance of HHSN routing protocols within the framework of the RSE theory. Existing reviews either treat routing merely as a component of broader surveys or lack analysis based on the RSE trilemma framework. Building on our review of HHSN routing protocols, we discuss the topology description and security aspects of HHSN and propose potential directions for future HHSN routing research.

Building on our review of HHSN routing protocols, we discuss the topology description and security aspects of HHSN and propose potential directions for future HHSN routing research.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"13 ","pages":"4883-4911"},"PeriodicalIF":7.9,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145879961","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}
The Internet of Medical Things (IoMT) consists of many resource-constrained medical devices that provide patients with medical services anytime and anywhere. In such an environment, the collection and sharing of medical records raise serious security concerns. Although various cryptographic schemes have been proposed, most fail to address two critical threats simultaneously: (i) sensitive data exposure caused by external cloud servers and/or open network environments; (ii) algorithm substitution attacks (ASAs) by internal adversaries. Furthermore, when data owners (e.g., delegators) are inconvenient to process their data, it is desirable to establish a more fine-grained way to delegate encryption rights. To tackle these issues, we propose a subversion-resistant autonomous path proxy re-encryption with an equality test function (SRAP-PRET). Specifically, our scheme allows the delegator to create a multi-hop delegation path in advance with the delegator's preferences, effectively preventing unauthorized access. By deploying a cryptographic reverse firewall zone, SRAP-PRET addresses the problem of information leakage caused by adversaries initiating ASAs. Additionally, SRAP-PRET also supports secure deduplication and efficient data decryption. Security analysis shows that SRAP-PRET provides resistance against ASAs and security against chosen plaintext attacks. Performance evaluations demonstrate that SRAP-PRET offers enhanced security properties without sacrificing efficiency.
