Existing Contract Theory-based methods are designed under the assumption that there is only one FL server in the system (i.e., the monopoly market assumption), which in unrealistic in practice. To address this limitation, we propose <underline>Fairness-<underline>Aware <underline>Multi-<underline>Server FL task delegation approach (<monospace>FAMuS</monospace>), a novel framework based on Contract Theory and Lyapunov optimization to jointly address these intricate issues facing wireless multi-server FL networks (WMSFLN). Within a given WMSFLN, a task requester products multiple FL tasks and delegate them to FL servers which coordinate the training processes. To ensure fair treatment of FL servers, <monospace>FAMuS</monospace> establishes virtual queues to track their previous access to FL tasks, updating them in relation to the resulting FL model performance. The objective is to minimize the time-averaged cost in a WMSFLN, while ensuring all queues remain stable. This is particularly challenging given the incomplete information regarding FL clients' participation cost and the unpredictable nature of the WMSFLN state, which depends on the locations of the mobile clients. Extensive experiments comparing <monospace>FAMuS</monospace> against five state-of-the-art approaches based on two real-world datasets demonstrate that it achieves 6.91% higher test accuracy, 27.34% lower cost, and 0.63% higher fairness on average than the best-performing baseline.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 2","pages":"684-697"},"PeriodicalIF":6.7,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465848","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, the vulnerability of Information and Communication Technology (ICT) infrastructures to cyberattacks, e.g., Denial of Service (DoS) attacks, poses a significant challenge. A possible solution is to use Digital Twin (DT) modeling of the physical system, which provides robust digital mapping and Big Data processing capabilities that facilitate data recovery. To this end, this paper proposes a DT-enabled energy trading framework for cyber-physical energy systems that offers data analytic and recovery capabilities to defend from DoS attacks. With this framework, a new distributed approximate-newton trading algorithm with a switched triggering control strategy is proposed. Therein, the DT model is employed to achieve data recovery and adjust the system evolution of trading trajectory during attack periods. This enables the proposed method to find optimal trading solutions even in the presence of DoS attacks. Theoretical analysis results demonstrate the correctness of the proposed method. Furthermore, numerical simulations are conducted to assess the effectiveness of the proposed method.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 2","pages":"669-683"},"PeriodicalIF":6.7,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464352","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}

Addressing the communication scenarios characterized by diverse task types, this paper introduces cloud-assisted mobile-edge computing (C-MEC) networks, underscored by a novel optimization scheme. The scheme incorporates a utility function that is correlated with offloading delays during the transmission and computation phases, effectively balancing resource allocations and enhancing the operational efficiency of vehicular networks. However, the mobility of vehicles introduces channel uncertainty, adversely affecting the offloading stability of C-MEC networks. To develop a practical channel model, a first-order Markov process is employed, taking into account vehicular mobility. Additionally, probability constraints regarding co-channel interference are imposed on signal links to ensure the offloading quality. The Bernstein approximation method is utilized to transform the original interference constraints into a tractable form, and the Successive Convex Approximation (SCA) technique is meticulously applied to address the non-convex robust optimization problem. Furthermore, this paper proposes a robust iterative algorithm to ascertain optimal power control and task scheduling strategies. Numerical simulations are conducted to assess the effective of the proposed algorithm against benchmark methods, with a particular focus on robustness in task offloading and utility in resource allocation.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 2","pages":"698-709"},"PeriodicalIF":6.7,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465697","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, the energy required for control becomes prohibitively large when the fraction of driver nodes is small. Previous methods to reduce control energy have mainly focused on increasing the number or altering the placement of driver nodes. In this paper, a novel approach is proposed to reduce control energy by rewiring networks while keeping the number of driver nodes unchanged. We model network rewiring to an optimization problem and develop a memetic algorithm to solve it accurately and efficiently. Specifically, we introduce a connectivity-preserving crossover operator to avoid searching in invalid solution space and design a local search operator to accelerate the convergence of the algorithm according to the network heterogeneity. Experimental results on both synthetic networks and real networks demonstrate the effectiveness of the proposed approach. Notably, our findings reveal that networks with low control energy tend to exhibit a âcore-chainâ structure, where control nodes and high-weight edges form a densely connected core, while other nodes and edges form independent chains connected to the core's boundaries. We further analyze the statistical description and formation mechanism of this structure.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 1","pages":"423-432"},"PeriodicalIF":6.7,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880410","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}

In this work, we present Qualified Proof of Stake (QPoS) scheme which alleviates centralization by rewarding truthful behavior of both voters and leaders, and penalizing their untruthful behavior. Leaders are elected according to the current stake which gives preference to more trustworthy nodes. Nodes with low stake at the end of a round which consists of multiple PBFT voting cycles are excluded from voting in subsequent rounds, while nodes with sufficient stake may leave the network temporarily without losing their stake. We consider multiple node classes with different voting behavior and model them using embedded Markov Chain which corresponds to Semi Markov Process (SMP) in order to determine system performance. Our results show the interaction of class populations, voting behavior, and mobility with round size, and show notable stake-based prioritization among the nodes for selection of PBFT leaders.

However, due to factors such as sampling strategies and failures in data transmission or storage, only incomplete monitoring data can be obtained. Traditional techniques for completing network monitoring data matrices have limitations in leveraging network-related features and lack the adaptability required for offline and online execution. In this paper, we introduce a novel approach that significantly improves the integration of network features and operational flexibility in data completion tasks. By converting the data matrix into a bipartite graph and integrating network features into the graph's node attributes, we redefine the problem of missing data completion. This transformation reframes the issue as estimating unobserved edges in the bipartite graph. We propose the Bi-directional Bipartite Graph Completion (BGC) model, a flexible framework that seamlessly adapts to both offline and online data completion tasks. This model encapsulates static, dynamic, bi-directional temporal features and network topology, thereby improving the accuracy of unobserved edge estimation. Experiments conducted on two public data traces demonstrate the superiority of our method over six baseline models. Our method not only achieves higher accuracy in offline scenarios but also displays remarkable speed in online situations.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 2","pages":"623-635"},"PeriodicalIF":6.7,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464351","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, challenges such as vulnerability to adversarial examples and non-independent and identically distributed (non-IID) data across devices hinder the deployment of adversarially robust and accurate models at the edge. While adversarial training (AT) is widely recognized as an effective defense strategy against adversarial attacks in centralized training, we shed light on the adverse effects of directly applying AT in FL, which can severely compromise accuracy under non-IID scenarios. To address this limitation, this paper proposes <underline>FatCC, which incorporates local logit <underline>Calibration and global feature <underline>Contrast into the vanilla federated adversarial training (<underline>Fat) process from both logit and feature perspectives. This approach effectively enhances the robust accuracy (RA) and clean accuracy (CA) of the federated system. First, we introduce logit calibration, where the logits are calibrated during local adversarial updates, thereby improving adversarial robustness. Second, FatCC incorporates feature contrast, which involves a global alignment term that aligns each local representation with corresponding unbiased global features, thus enhancing robustness and accuracy. Extensive experiments across multiple datasets demonstrate that FatCC achieves comparable or superior performance gains in both CA and RA compared to other baselines.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 2","pages":"636-652"},"PeriodicalIF":6.7,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464347","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}

These methods directly predict operational states of power systems according to given conditions, such as loads, states of buses, topology, etc. However, we find that the neighborhood aggregation of the graph convolution architecture violates operational constraints of power systems. In this paper, a global-receptive graph iteration architecture that overcomes this shortcoming is designed to replace the graph convolution architecture. Specifically, Newton's method, one of the most classical methods for PF, is embedded into the graph iteration network (GIN) to form an implicit residual learning architecture. To retain the interpretability, the GIN follows a non-activation paradigm, in which the ability of non-linear representation stems from the iterative architecture rather than the activation function. Finally, without the demand to reclaim global information, the GIN allows shallower network structure by eliminating fully connected layers. Extensive numerical experiments are conducted on IEEE 30-bus, 57-bus, 118-bus, and 300-bus power systems.
