Wireless Federated Learning (FL) is a distributed Artificial Intelligence (AI) framework, enabling decision-making at the network edge where data are generated. However, wireless transmissions of model updates from edge nodes to the coordinating server are vulnerable to jamming, alongside the inherent risk of poisoning the learning process. In this paper, we tackle the problem of coordinated jamming and poisoning attacks in wireless FL networks, where malicious edge nodes disrupt transmissions of legitimate local model updates to the cloud server while injecting poisoned model updates to manipulate the global model. To this end, we introduce two complementary mechanisms operating alternately. First, a robust global model aggregation algorithm is developed to address poisoning attacks by weighting edge nodes’ local model updates using a novel contribution index. The calculation of the index is inspired by the Shapley value, but it offers polynomial complexity compared to existing methods. Subsequently, a distributed power control solution for jamming attack mitigation in the uplink of the FL network is introduced based on Bayesian games with incomplete information. Both legitimate and malicious nodes aim to successfully transmit their model parameters, minimizing transmission power and time to the server, while having probabilistic knowledge about the malicious behavior of the other nodes in the game. The proposed unified approach and each individual mechanism are assessed via modeling and simulation, verifying their effectiveness in mitigating both attacks while achieving a good tradeoff between global model accuracy and consumed time and energy compared to state-of-the-art approaches. © 2020 IEEE.

In response to the problem of traditional methods ignoring audio modality tampering, this study aims to explore an effective deep forgery video detection technique that improves detection precision and reliability by fusing lip images and audio signals. The main method used is lip-audio matching detection technology based on the Siamese neural network, combined with MFCC (Mel Frequency Cepstrum Coefficient) feature extraction of band-pass filters, an improved dual-branch Siamese network structure, and a two-stream network structure design. Firstly, the video stream is preprocessed to extract lip images, and the audio stream is preprocessed to extract MFCC features. Then, these features are processed separately through the two branches of the Siamese network. Finally, the model is trained and optimized through fully connected layers and loss functions. The experimental results show that the testing accuracy of the model in this study on the LRW (Lip Reading in the Wild) dataset reaches 92.3%;the recall rate is 94.3%;the F1 score is 93.3%, significantly better than the results of CNN (Convolutional Neural networks) and LSTM (Long Short-Term Memory) models. In the validation of multi-resolution image streams, the highest accuracy of dual-resolution image streams reaches 94%. Band-pass filters can effectively improve the signal-to-noise ratio of deep forgery video detection when processing different types of audio signals. The real-time processing performance of the model is also excellent, and it achieves an average score of up to 5 in user research. These data demonstrate that the method proposed in this study can effectively fuse visual and audio information in deep forgery video detection, accurately identify inconsistencies between video and audio, and thus verify the effectiveness of lip-audio modality fusion technology in improving detection performance.

IoT involves sensors for monitoring and wireless networks for efficient communication. However, resource-constrained IoT devices and limitations in existing wireless technologies hinder its full potential. Integrating UAVs into IoT networks can address some challenges by expanding its coverage, providing security, and bringing computing closer to IoT devices. Nevertheless, effective data collection in UAV-assisted IoT networks is hampered by factors, including dynamic UAV behaviour, environmental variables, connectivity instability, and security considerations. In this survey, we first explore various communication technologies for UAV-IoT networks, performance metrics, and simulation tools, followed by a categorization of the UAV-IoT system based on the service model of UAV, mode of operation of UAV and UE during data collection, and network topology. As this article primarily emphasizes reliable and efficient data collection in UAV-assisted IoT networks, we briefly discuss existing research on data accuracy and consistency, network connectivity, and data security and privacy to provide insights into reliable data collection. Additionally, we discuss efficient data collection strategies in UAV-based IoT networks, covering trajectory planning and constraint management, sensor network clustering, data aggregation, and UAV swarm formations. Further, advanced AI techniques are discussed, which enable efficient and reliable data transfer in UAV-IoT systems. Finally, we discuss future challenges and their possible solutions using different approaches such as Decentralized Reinforcement and Federated Learning, Generative AI, and hybrid optical-RF communication links with integration of blockchain for reliable, efficient, and secure data collection in UAV-assisted IoT networks. © 2025 IEEE.

Urban traffic congestion poses a major challenge, particularly for emergency services like ambulances, where delays can have life-threatening consequences. This paper proposes a novel, cost-efficient Automated Traffic Light Control System aimed at prioritizing ambulances at busy intersections, thereby reducing delays and ensuring faster response times. The system utilizes Raspberry Pi Zero 2W, Laser Diodes (KY-008), and Light Dependent Resistors (LDRs) to detect ambulances and dynamically control traffic lights. Unlike traditional systems relying on GPS or RFID technologies, this laser-based approach offers greater precision and affordability through the use of modulated laser signals. Experimental results reveal that this system reduces ambulance response times by 35%. The tests were conducted under simulated urban conditions, highlighting the system's capability to outperform conventional solutions. The simplicity of integration and real-time responsiveness underscore its potential for widespread urban adoption.

With the rapid evolution of Web3.0, cryptocurrency has become a cornerstone of decentralized finance. While these digital assets enable efficient and borderless financial transactions, their pseudonymous nature has also attracted malicious activities such as money laundering, fraud, and other financial crimes. Effective detection of malicious accounts is crucial to maintaining the security and integrity of the Web 3.0 ecosystem. Existing malicious account detection methods rely on large amounts of labeled data and suffer from low generalization. label-efficient and generalizable malicious account detection remains a challenging task. In this paper, we propose ShadowEyes, a framework for detecting malicious accounts by leveraging interaction feature learning with only a small labeled dataset. Specifically, We first propose a generalized account representation named TxGraph, which captures the universal interaction features of Ethereum and Bitcoin. Then we carefully design an account representation augmentation method tailored to simulate the evolution of malicious accounts to generate positive pairs. We conduct extensive experiments using public datasets to evaluate the performance of ShadowEyes. The results demonstrate that it outperforms state-of-the-art (SOTA) methods in four typical scenarios. Specifically, in the scenario of acrossplatform malicious account detection, ShadowEyes maintains an F1 score of around 90%, which is 10% higher than the SOTA method. In the zero-shot learning scenario, it can achieve an F1 score of 79.56% for detecting gambling accounts, surpassing the SOTA method by 10.44%. © 2005-2012 IEEE.

The control of heliostats in existing Concentrated Solar Power (CSP) fields is performed based on wired communications, resulting in high installation, maintenance, and operation cost. This paper introduces a wireless communication system for CSP fields based on the Integrated Access and Backhaul (IAB) technology, a distributed resource management mechanism, and an artificial intelligent or AI-based clustering mechanism for the heliostats. The proposed system ensures efficient communication between the heliostats and their cluster-heads as well as among the cluster-heads themselves in order to communicate with the Central Station (CS) residing in the CSP field. The clustering is optimized using the Optimistic Q-learning with Upper Confidence Bound (OQ-UCB) algorithm, accounting for the CSP fields' topology and channel gain characteristics. Furthermore, a game-theoretic approach is employed to optimize the transmission power and bandwidth allocation, aiming to enhance the energy efficiency while meeting the stringent latency demands of the heliostat autocalibration. Experiments and numerical results from a CSP field with 7,683 heliostats validate the system's efficacy in maintaining robust wireless communication and energy efficiency and highlight the proposed model's capability to support the wireless communication needs of CSP fields. © 2017 IEEE.

Symbiotic Resource Pricing in the Computing Continuum Era

IEEE Transactions on Mobile Computing 2025年

Though extensive research efforts have been devoted to the problem of computing resource pricing, they mainly focus on single computing paradigms. In this paper, we provide a holistic approach to this problem, by treating the whole computing continuum, consisting of cloud, edge, and fog computing providers, simultaneously offering their resources to the users. Within such a complex setting, we establish the concept of symbiotic computing resource pricing and sharing, where the computing providers and the users coexist within a mutually beneficial ecosystem, sharing services and resources as a means of ensuring their business survival and service satisfaction. Under this prism, we introduce two key pricing families, namely the non-cooperative one which involves competition and is treated through game theoretic approaches, and the cooperative resource pricing (full or partial), which addresses complex scenarios through optimization and coalition. A thorough performance assessment is provided, through modeling and simulation, in order to highlight and quantify the key characteristics and tradeoffs of the various resource pricing approaches introduced. © 2002-2012 IEEE.

This study introduces a deep learning-based method for classifying brain tumors using a pre-trained VGG19 convolutional neural network (CNN). By leveraging transfer learning, we adapted the VGG19 model with custom fully connected layers and trained it on MRI images to differentiate between tumor and non-tumor cases. The model’s architecture includes dropout layers to minimize overfitting and enhance generalization while maintaining the robust feature extraction capabilities of the VGG19 base. We developed a Flask web application interface to make the model accessible via web-based user input, allowing users to upload MRI images and receive immediate predictions on tumor presence. Preliminary results show that proposed model can accurately classify brain tumor images with high accuracy, highlighting the potential of deep learning in automating brain tumor diagnostics. This tool could significantly aid clinicians in making rapid and accurate diagnoses, ultimately improving patient outcomes.

SAFLA: Semantic-Aware Full Lifecycle Assurance for Intent-Driven networks

引用

IEEE Transactions on Cognitive Communications and Networking 2025年

Intent-Driven networks (IDNs) are designed to improve network management efficiency by transforming high-level intents into actionable configurations. Due to evolving user requirements and network dynamics, a semantic gap has emerged between declarative intents and underlying configurations, posing significant challenges to the assurance and reliability of IDNs. Despite promising preliminaries, existing intent assurance approaches, which mainly focus on monitoring intents’ Key Performance Indicators (KPIs), fail to bridge the semantic gap. This gap can result in configurations that technically meet KPIs from a top-down perspective but fail to accurately reflect the original network intent from a bottom-up view, leading to serious security risks and undermining overall objectives. To address this issue, we introduce SAFLA, a semantic-aware framework designed to ensure the intent’s full lifecycle. By seamlessly integrating top-down and bottom-up approaches, SAFLA not only enhances intent assurance by monitoring intent performance but also bridges the semantic gap between high-level intents and low-level configurations. This integration facilitates a self-healing mechanism for IDNs, reducing the need for manual intervention even under evolving requirements and network reconfigurations. Experimental results on software-defined Networking demonstrate the SAFLA’s feasibility and efficiency in intent assurance. © 2015 IEEE.

To overcome the limited endurance of traditional unmanned aerial vehicles (UAVs), we propose a network of robotic aerial base stations (RABSs) that can energy-efficiently anchor into tall urban landforms, such as lampposts. This approach enables the creation of a hyper-flexible wireless multi-hop network, designed to support green, densified, and dynamic network requirements, thereby ensuring reliable long-term coverage for the whole observed region. The proposed network infrastructure can concurrently address the backhaul link capacity bottleneck and support access link traffic demand in the millimeter-wave (mmWave) frequency band. Specifically, the RABSs grasping locations, resource blocks (RBs) assignment, and route flow control are simultaneously optimized to maximize the served traffic demands. The group of RABSs capitalizes on the fact that traffic distribution varies considerably across both time and space within a given geographical area. Hence, they are able to relocate to suitable locations, i.e., ‘follow’ the traffic demand as it unfolds to increase the overall network efficiency. To tackle the curse of dimensionality of the proposed mixed-integer problem, we propose a greedy algorithm to obtain a competitive solution with low computational complexity. A wide set of numerical investigations reveals that RABSs could improve the served traffic demand. For instance, compared to networks with randomly deployed fixed small cells, the proposed mode serves at most 65% more traffic demand.
