Second, the possibility of unreliable and malicious participants preventing model convergence and degrading performance is not considered. To address the above issues, a secure and efficient FL scheme RAFL for LEO constellations is proposed. RAFL employs aerial networking and hierarchical FL to reduce interactions between satellites and ground station, thereby enhances training efficiency and model performance. A self-adaptive reputation evaluation system is designed that incorporates malicious behavior detection, historical behavior analysis, and performance and contribution assessments of LEO satellites.

Applications like autonomous vehicles, smart farming, smart healthcare systems and more are all possible uses for them. Smart farming is a form of agricultural management that makes use of contemporary information and communication technologies (ICTs) in order to improve both the amount and quality of the products that are produced. Next-generation wireless networks facilitate smart farming. The primary goals of smart farming are to supply the agricultural industry with the infrastructure that is required to track, monitor, automate, and analyze processes utilizing cutting-edge techniques such as machine learning, big data, cloud computing, and the Internet of Things (IoT). These are some of the technologies that are being utilized in smart farming. Smart farming employs techniques to create varied forecasts. From a descriptive dashboard, such as a mobile app or Web app, the farmers can keep an eye on their crops and make selections based on their findings. However, such a system may be vulnerable to various cyber threats and attacks as the devices and servers exchange their data through an insecure medium (i.e., the Internet). In this study, we present an authenticated key agreement technique for secure big data analytics in next-generation wireless networks-enabled smart farming (in short, AKM-BDSF) to protect the transferred and stored data of smart farming.

Therefore, users can only securely access legitimate service providers in a single registration by presenting both passwords and biometrics.

However, outliers clustered in activation channels tend to dominate the quantization range and induce significant accuracy degradation. To address the outlier challenge, this paper proposes an outlier resilient PTQ method through outlier decomposition, namely ORQ-ViT. Its core idea is to decompose outliers clustered in outlier channels into isolated outliers, so that they can be easily excluded, thus alleviating their adverse impact. Specifically, we decompose activations along the patch token dimension. Since there are very few outlier channels, decomposed rows after outlier decomposition usually cover several isolated outliers, which can be easily identified and filtered. We further design an adaptive quantization range determination strategy during quantization parameters initialization to prevent outliers from serving as boundary values of the quantization range. ORQ-ViT can improve quantization levels utilization to generate activations with higher quantization resolution, thereby achieving higher accuracy. Additionally, ORQ-ViT supports pure integer matrix multiplications to ensure the inference efficiency of quantized ViTs on edge hardware. Extensive experiments demonstrate that our method achieves state-of-the-art (SOTA) accuracy across various ViT variants under multiple low bit-width scenarios. For image classification, the top-1 accuracy of ORQ-ViT outperforms that of the SOTA methods by an average of 2.26% at W4A4. Even for object detection and instance segmentation, ORQ-ViT also delivers highly competitive results. We also evaluate the inference efficiency of pure integer matrix multiplications and the results show that our method can achieve up to 2.1× speedup.</div></div>","PeriodicalId":50027,"journal":{"name":"Journal of Systems Architecture","volume":"168 ","pages":"Article 103530"},"PeriodicalIF":4.1,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144908217","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}
