We consider estimation problems, such as cooperative localization and federated learning, where the data collected at any agent depends on a subset of all variables of interest. We provide a unified formulation of centralized, distributed and marginal probabilistic estimation as a Bayesian density estimation problem using data from non-linear likelihoods at agent. We develop distributed estimation algorithms based on stochastic mirror descent with appropriate regularization to enforce distributed or marginal density constraints. We prove almost-sure convergence to the optimal set of probabilities at each agent in both the distributed and marginal settings. Finally, we present Gaussian density versions of these algorithms and compare them to belief propagation variants in a node localization problem with relative position measurements.

These networks facilitate the propagation of information. Traffic between any two nodes demanded at any time is routed along the fastest time-respecting path. In this work, we investigate the vulnerability of information transport on temporal networks to link removal. The objective is to understand the removal of which types of links deteriorate the efficiency/speed of information transport the most. Identifying such critical links will enable better intervention to facilitate/prohibit the spread of (mis)information. To identify critical links, we propose link-removal strategies based on transport efficiency between two end nodes of each link, properties of links in the aggregated network, and in routing paths respectively. Each strategy ranks links according to their corresponding properties and removes links with the highest measures. Strategies are evaluated via the relative change in transport efficiency after link removal in real-world networks. We find that the path-based strategy performs the best: links appear more often and occur early in the fastest time-respecting paths tend to be critical. Via comprehensive analysis, we explain this strategy's out-performance and its dependency on network properties.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 4","pages":"2932-2941"},"PeriodicalIF":6.7,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492248","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}

Restricted by the limitations of on-chip memory resources and the speed of packet processing, most existing solutions use compact data structures, namely sketches, to facilitate line-speed measurement. Nevertheless, these sketches, due to their shared record units (bits/counters) among flows, inevitably introduce noise into the measurement result of each flow. While conventional average denoising strategies can mitigate noise from raw estimates, they fall short of providing sufficient accuracy for medium-sized flows, primarily due to the uneven distribution of noise. To complement prior work, we propose two algorithms, ADN and mADN, which can perform denoising by considering the sizes of shared flows. ADN employs an optimization algorithm to model interconnections among flows, thereby reconstructing noise propagation and accurately restoring their sizes. Meanwhile, mADN retains the benefits of ADN yet excels in being more memory-efficient and precise. We apply our estimators to five essential tasks: per-flow size estimation, heavy hitter detection, heavy change detection, distribution estimation, and entropy estimation. Experimental results based on real Internet traffic traces show that our measurement solutions surpass existing state-of-the-art approaches, reducing the mean absolute error by approximately an order of magnitude under the same on-chip memory constraints.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 4","pages":"2907-2920"},"PeriodicalIF":6.7,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492214","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, user association, distributed resource allocation, and the high-speed data rate demands of different users still face numerous challenges. To address these issues, we propose a UAV-assisted RAN resource slicing framework in heterogeneous networks. Firstly, we employ a stable matching game algorithm to solve the access problem between UAVs (unmanned aerial vehicles) and TBSs (terrestrial base stations). Secondly, we formulate a joint user association and slicing resource allocation problem. However, the optimization problem is non-convex, and the problem is decoupled into two sub-problems: user association and slicing resource allocation. Moreover, a Lagrangian dual algorithm is employed to solve the user association problem, while Multi-Agent Deep Deterministic Policy Gradient based on Matching Game and Lagrangian Dual (MADDPG-M&L) slicing resource allocation algorithm is proposed to determine the allocation ratio of resources for each slice. Simulation results show that the Lagrangian dual-based user association algorithm improves the system performance by 12.8%, 36.2% and 61.9% respectively compared to the other three user association methods. Furthermore, compared to MATD3-M&L, MASAC-M&L, and Hard-slicing, the proposed MADDPG-M&L algorithm improves the throughput by 36.3%, 105%, and 177%, respectively. In terms of latency, the improvements are 46%, 68%, and 86.7%, respectively. For SINR, the increases are 5.2%, 2.9%, and 6.4%, respectively. The objective function improves by 54.7%, 218%, and 336%, respectively, with the data transmission rate showing the most significant improvement.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 4","pages":"2878-2894"},"PeriodicalIF":6.7,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492277","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}

To address the issue posed by the nonidentical system dynamics of multiple leaders, which makes the traditional distributed estimator form for the convex hull inapplicable, a distributed finite-time estimator is constructed for each follower to extract the system matrices and states of leaders. Then, in the output-triggering setting, a finite-time extended state observer driven by intermittent output measurement is developed to reconstruct the uncertainties and unmeasurable states of followers. Meanwhile, the non-continuous output measurement will lead to the differentiation of virtual control laws undefined. To solve this issue, a filtering compensation scheme-based finite-time controller via the backstepping technique is developed for nonlinear followers, ensuring practical finite-time stability (PFTS) of the closed-loop system. It is shown that the proposed algorithm steers each follower into the preset convex combination spanned by the positions of multiple leaders. The capability of the exploited control protocol is verified through simulations and experiments.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 4","pages":"2823-2834"},"PeriodicalIF":6.7,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492224","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}

Specifically, we consider the class of networked susceptible-infected-susceptible (SIS) epidemics where a large population of agents strategically choose whether to adopt partially effective protection. We define the utilities of the agents which depend on the degree of the agent, its individual infection status and action, as well as the the overall prevalence of the epidemic and strategy profile of the entire population. We further present the coupled dynamics of epidemic evolution as well as strategy update which is assumed to follow the replicator dynamics. By relying on timescale separation arguments, we first derive the game-theoretic protection adoption strategies of the agents for a given epidemic state, and then present the reduced epidemic dynamics. The existence and uniqueness of endemic equilibrium is rigorously characterized and forms the main result of this paper. We then present extensive numerical results to highlight the impacts of heterogeneous node degrees, infection rates, cost of protection adoption, and effectiveness of protection on the epidemic prevalence at the equilibrium.

In the considered open MASs, agents can join or leave the network at any time, which leads to a changeable system size. To address this challenge, we propose a fully distributed control framework that enables agents with heterogeneous dynamics to converge to NE at an exponential rate, using only limited information exchange and localized computation. Additionally, an adaptive strategy is introduced, where the control gains of each agent are adjusted based on local adjacent information. This adjustment allows the system to adapt in real-time to environmental changes. We establish sufficient conditions for the existence of NE in both fixed and varying agent numbers, even in the presence of DoS attacks. Through rigorous theoretical analysis, the proposed adaptive algorithm is proven to guarantee the convergence of the hybrid heterogeneous MAS to the NE despite sustained or intermittent DoS attacks.

In city-wide traffic data recovery tasks, traditional centralized deep-learning-model training strategies become inapplicable because of the expensive storage costs for large-scale traffic datasets. In this scenario, edge computing emerges as a natural choice, allowing decentralized data storage and distributed training on edge nodes. However, there is still a challenge: distributed training on edge nodes suffers from high communication costs for parameter transmission. In this paper, we propose a communication-efficient Graph-Tensor Fast Iterative Shrinkage-Thresholding Algorithm-based neural Network (GT-FISTA-Net) for distributed traffic data recovery. Firstly, we model the recovery task as a graph-tensor completion problem to better capture the low-rankness of traffic data. A recovery guarantee is also provided to characterize the performance bounds of the proposed scheme in terms of recovery error. Secondly, we propose a distributed graph-tensor completion algorithm and unfold it into a deep neural network called GT-FISTA-Net. GT-FISTA-Net requires small communication costs for distributed model training on edge nodes and thus it is applicable for city-wide traffic data recovery. Extensive experiments on real-world datasets show that the proposed GT-FISTA-Net can also provide excellent recovery accuracy compared with state-of-the-art distributed recovery methods.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 4","pages":"2835-2847"},"PeriodicalIF":6.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492313","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}

To solve the difficulty that smart contracts on the blockchain cannot interact with the real world, some blockchain oracle implementation schemes have been proposed. However, the existing data feed schemes still cannot meet the demand of off-chain intensive data feed. This paper introduces a directed acyclic graph (DAG)-distributed ledger into the blockchain oracle data feed scheme, to propose a DAG-distributed ledger-based decentralized oracle network (DDON) framework. The lightweight DAG consensus mechanism ensures data integrity and significantly reduces the entry of valueless information into the DDON, ultimately generating deterministic data. The proposed DAG structure enables parallel processing of transactions and accelerates the efficiency of data feeds. This also enables the feeding of historical data. In addition, an off-chain data feed mechanism is designed for off-chain intensive streaming of data feeds through the proposed oracle network, to separate data feeds from data fetches and improve the efficiency of feeding multiple requests. The evaluation results and discussions demonstrate that the proposed framework reduces the response time for every smart contract request and is more efficient and flexible than other mainstream oracle data feed services.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"12 4","pages":"2810-2822"},"PeriodicalIF":6.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492432","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}
