However, in practice, payment channels often suffer from balance depletion on one side, preventing further transactions from being executed through that channel. Rebalancing methods can alleviate this issue by actively shifting available balances across different payment channels to replenish depleted ones at minimal cost. However, existing rebalancing methods often determine the target balance of each channel subjectively, without ensuring that the rebalancing operation effectively increases the total value of executable transactions or maximizes balance-shifting efficiency within the PCN. To address these limitations, this paper establishes rebalancing evaluation models to quantify the impact of individual rebalancing operations on the total executable transaction value within the PCN. Based on these models, we design a hybrid rebalancing method that adaptively adjusts the rebalancing operation type, target balance, and participant selection according to the available balance and transaction workload of each payment channel, thereby maximizing the overall benefit of rebalancing operations on the total executed transaction value of the PCN. Experimental results demonstrate that our method improves the transaction success rate by up to 34.7% and reduces the average transaction latency by up to 4.4% compared with existing methods.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"13 ","pages":"6995-7013"},"PeriodicalIF":7.9,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362314","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 realize the economic and flexible operation of data centers, this paper proposes a spatio-temporal coordinated operation strategy of data centers considering virtual storage system (VSS) via two-stage distributionally robust optimization. First, based on the dynamic thermal network of buildings and differentiated demands of cloud users in data centers, a comprehensive operation model with VSS is proposed. Then, considering uncertainties of general load demands from data centers and outdoor temperatures, a fuzzy set is deduced, using an imprecise Dirichlet model derived from historical data. This ensures confidence level satisfaction for uncertain sets of general load and outdoor temperatures. In addition, the spatio-temporal coordinated operation strategy of data centers considering virtual storage system via two-stage distributionally robust optimization that flexibly adjusts conservativeness through uncertainty regulation parameters. Finally, a Dynamic Accuracy Column and Constraint Generation (DA-C&CG) algorithm is developed for solving the proposed strategy.

To address these challenges, we propose a novel UAV-mounted reconfigurable intelligent surface (RIS) assisted approach, where the RIS is deployed on the jammer UAV to create an additional surveillance channel towards the legitimate UAV. Furthermore, the jammer UAV can also intelligently adjust its power allocation and flight trajectory to covertly disturb the suspicious transmission with the detection thresholds and the energy budgets. In such a setup, we consider a sum eavesdropping rate maximization problem of the legitimate UAV during all time slots. This formulated problem is solved by jointly optimizing the three-dimensional (3D) trajectory of the legitimate UAV, the reflecting phase shifts of the RIS, as well as the 3D trajectory and jamming power of the jammer UAV under the mobility, covertness, and power limitation constraints. We decompose the non-convex design problem into three subproblems and propose an iterative algorithm to find its approximated optimal solution by using the block coordinate descent method.

This indirect nature forces the victim area to rely on upstream networks for collaborative defense against LFA. For upstream networks, rerouting serves as a rapid and effective defense strategy. However, each rerouting incurs costs for the upstream network, making it reluctant to assist the victim without compensation. Therefore, we propose EcoShield, in which rerouting is regarded as a tradable service and the victim can purchase from relevant networks when needed. To implement EcoShield, we face two challenges: building a collaboration platform to ensure fair service trading and minimizing the victim’s defense expense. To this end, we propose a blockchain-based collaborative architecture for rerouting service trading. Furthermore, we propose a cost-efficient collaborative rerouting scheme toward suspicious source domains, which effectively reduces the number of reroutings required, thereby reducing the victim’s expense. Finally, extensive experiments demonstrate that, while ensuring effective defense performance (with a botnet identification <italic>precision above 0.95 and <italic>recall above 0.6), EcoShield reduces the defense expense by at least 45% compared with prior works.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"13 ","pages":"7014-7030"},"PeriodicalIF":7.9,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362307","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, existing solutions, such as the IEEE 802.15.6 standard and other adaptive TDMA protocols, fail to adequately address the inherent challenges of node heterogeneity and network dynamics, which lead to inefficient resource allocation, unreliable emergency handling, and inflexible Quality-of-Service (QoS) provisioning. In this article, we propose a Heterogeneity-Aware Proactive MAC (HAP-MAC) protocol that introduces a novel three-tier holistic framework for resource allocation. Unlike conventional methods reliant on static priorities or slow centralized adaptations, HAP-MAC enables intelligent and autonomous node-state adaptation based on real-time buffer status, delay constraints, and channel quality. It employs a predictive channel access mechanism for microsecond-scale arbitration and a sophisticated multi-dimensional priority framework that comprehensively evaluates traffic characteristics, data volume, buffer conditions, and time sensitivity, thus ensuring precise QoS differentiation for diverse application requirements. Extensive experimental results demonstrate that HAP-MAC delivers significant performance advantages over state-of-the-art protocols in terms of total throughput, packet delivery rate, average delay, and channel utilization. HAP-MAC exhibits a unique ability to simultaneously address node heterogeneity and network dynamics, making it an ideal solution for mission-critical healthcare monitoring applications.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"13 ","pages":"6843-6854"},"PeriodicalIF":7.9,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147299497","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 contrast, the dynamic GSE is better suited for changing real world, but enhancing its search efficiency remains a formidable challenge. In this paper, we propose the ParallelGSE, a flexible graph partitioning and parallel search framework that supports both dynamic and static encrypted social graphs, striking a balance between query privacy and practical implementation. ParallelGSE partitions the original graph into multiple subgraphs, distributes them across several semi-honest servers, and performs searches in parallel without relying on a trusted server. Formal security reduction demonstrates ParallelGSE is resistant to isomorphic query recovery attacks. Simulated experiments on seven real-world graph datasets validate rationality of graph partition and improvements of storage, computation and communication costs. Especially, compared to the state-of-the-art (SOTA) static PathGES (ACM CCS 2024) and dynamic GraphShield (IEEE TKDE 2022), the search efficiency of static ParallelGSE can be 3 orders of magnitude faster than that of PathGSE, while dynamic ParallelGSE achieves over <inline-formula><tex-math>$20times$</tex-math></inline-formula> greater search efficiency than GraphShield.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"13 ","pages":"7031-7050"},"PeriodicalIF":7.9,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362232","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 services cut off the direct link between input and output addresses to conceal publicly available transaction traces on the blockchain, thereby evading regulatory investigations. In recent years, significant efforts have been made to deanonymize Bitcoin mixing services (BMS). While these efforts have yielded some achievements in service detection, they still face several challenges, such as vague theoretical definitions, coarse-grained identification capabilities, and insufficient labeling information. To address these challenges, this paper formalizes the notion of BMS with a syntax, security model, and goals, providing a universal definition for evaluating service anonymity and detection feasibility. We also propose a fine-grained detection framework for BMS, called BMS-FDET, which leverages heterogeneous Bitcoin transactional networks and multiple attention mechanisms to identify mixing transactions across different services. To improve the model’s detection capabilities and compare performance, a sufficient ground-truth dataset with over 596,200 entries covering more than 15 mixing services is built from extensive data sources.

To enhance the security of the UAV transmitter, this paper investigates the jammer-assisted UAV covert communication systems with imperfect channel state information (CSI), where a subset of friendly jammers is selected to send artificial noise (AN) to confuse the warden. It is important to jointly optimize the jammer selection and jamming power, as AN sent by friendly jammers will interfere with the warden and receiver, simultaneously. However, existing channel-aware schemes work with a perfect CSI of the transmitter-to-receiver and jammer-to-receiver links, which is impractical in low-altitude networks. Therefore, this paper concerns the imperfect CSI of the transmitter-to-receiver link, and the channel distribution information (CDI) of both the transmitter-to-warden and jammer-related links. First, given the imperfect CSI, the warden's average detection error probability (WADEP) is analyzed. Then, given that WADEP is higher than the covertness constraint, the covert throughput is analytically derived and maximized by jointly optimizing the jammer selection, jamming power, and transmission rate (J-JamSPRImCSI). Since the optimization problem is NP-hard, a two-step Jensen's inequality based algorithm is proposed to provide a heuristic solution (2-Step-JIHA). Numerical results show that the proposed 2-Step-JIHA can provide a near optimal covert throughput with a lower complexity. Moreover, when the CSI is imperfect, compared to the existing channel-aware scheme, the proposed J-JamSPR-ImCSI with 2-Step-JIHA can improve the covert throughput by 54.26<inline-formula><tex-math>$%$</tex-math></inline-formula>, when the covertness constraint is 0.9.","PeriodicalId":54229,"journal":{"name":"IEEE Transactions on Network Science and Engineering","volume":"13 ","pages":"6958-6976"},"PeriodicalIF":7.9,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362393","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 system operates in discrete time slots, where contents can be retrieved in the following order: local cache, socially-connected D2D peers, and remote content servers. D2D sharing is restricted to users with social ties, quantified by a multi-attribute model combining interest similarity and social trust. We intend to maximize total backhaul bandwidth savings by jointly optimizing content placement, D2D user pairing, and base station (BS) bandwidth allocation, under constraints on storage capacity, unique pairing, total BS bandwidth, and service delay, etc. Given the NP-hardness of this joint optimization problem, we propose an Improved Constrained Fireworks Algorithm (ICFWA) that efficiently explores the solution space with low complexity and strong global search capability.
