However, training machine learning and deep learning (ML/DL) models in fog environments remains challenging due to limited computational resources. Despite the availability of numerous distributed ML frameworks, there is a lack of a comprehensive evaluation tailored to fog devices. This study conducts a comparative analysis of distributed ML frameworks for neural network training on resource-constrained fog nodes, using Raspberry Pi (RPi) devices. We started with Actor programming model-based frameworks and the study extended to general purpose distributed frameworks suitable for fog computing devices. We evaluate four actor-model-based frameworks (Akkordeon, DistBelief with Akka, Aktorain, and CANTO) along with general-purpose distributed frameworks (KubeRay, TensorFlow MultiWorkerMirroredStrategy (MWMS), Dask Distributed and Spark with Elephas). The frameworks are compared across key metrics including training time, accuracy, and resource utilization on diverse datasets. Our results highlight performance trade-offs: KubeRay offers a balance between efficiency and performance, Dask and MWMS achieve higher accuracy with increased latency, while Spark with Elephas excels in speed but struggles with accuracy. Although CANTO is optimized for fog-based training, it faces challenges with complex datasets. Overall, KubeRay emerges as the most practical choice for fog-based ML training because of its additional support for scalability and fault tolerance. This work bridges a critical research gap by providing experimental insights into the feasibility and performance of distributed ML frameworks in fog computing environments.</div></div>","PeriodicalId":29968,"journal":{"name":"Internet of Things","volume":"34 ","pages":"Article 101774"},"PeriodicalIF":7.6,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As vulnerabilities are closely tied to specific firmware versions, fine-grained version identification is critical for effective device management and security risk assessment. However, high firmware heterogeneity and subjective biases in feature selection pose significant challenges to online firmware version identification (OFVI) of IoT devices. To address these challenges, we first construct a dataset comprising 444,195 embedded web pages extracted from 1,000 successfully simulated firmware images. Through analyzing update patterns of embedded web interfaces during firmware version evolution, we propose <em>FirmID</em>, a novel OFVI framework for IoT devices that utilizes directory and content changes in embedded web interfaces. To handle the heterogeneity of firmware across different vendors, we introduce the Hierarchical Multimodal Attention Network (HMANet), a machine learning model specifically designed to capture differences across structural, textual, and functional modalities. To overcome the challenge of distinguishing hard samples caused by the frequent reuse of web pages in firmware iteration versions, we design a Hard Negative Mining Contrastive Loss that enhances intra-class compactness and inter-class separability. Moreover, to improve identification efficiency under uncertain network conditions, FirmID incorporates a complementary heuristic search algorithm, Firmware Identification with Monte Carlo Tree Search (FIMCTS). Experimental results demonstrate that FirmID surpasses state-of-the-art methods by 30.2% in accuracy and reduces file requests by 23.3% in recognition efficiency.</div></div>","PeriodicalId":29968,"journal":{"name":"Internet of Things","volume":"34 ","pages":"Article 101767"},"PeriodicalIF":7.6,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efficient orchestration of communication, computation, caching, and energy resources is imperative to maximize the benefits of UAV-assisted MEC networks. Additionally, ensuring high situational awareness is essential for supporting priority-based latency-sensitive applications.
