Industrial Internet of Things (IIoTs) comprises large-scale sensors deployed to monitor and control the system. Deploying IoT devices presents challenges due to frequent disconnections and sudden power drainage in intermediate devices responsible for routing data. Consequently, the deployed network becomes sporadic, hindering connectivity with the industrial controller system, especially critical during emergencies. Furthermore, IoT node failures lead to a short network lifetime, which is intolerable in real-time industrial applications. This paper introduces a multi-hop clustering framework designed for reliable communication in industrial environments. The framework dynamically forms clusters, employing cluster heads and backup nodes to stabilize communication in the absence of a cluster head. Each cluster selects a backup node during the initial cluster head selection and later through data piggybacking. The proposed framework provides efficient communication across the IIoT network with the help of a backup and multi-hop clustering mechanism. The proposed framework is compared with two existing protocols i.e. cluster-based coordination routing (CRC) and energy-efficient quality of service routing (EEQSRP) protocols. The results show a considerable decrease in sensor energy consumption and packet delay. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

The use of robotic arms in industrial and academic settings has grown exponentially, however, the process of simulating and operating these systems continues to be a significant challenge, particularly for users without prior experience. The learning curve is steep due to the technical complexity associated with programming, calibrating and controlling precise movements, which can be daunting. Robotic devices are usually controlled using proprietary software or ad-hoc low-level programs, hindering their shared use and integration with other applications. This work presents a software application for robotic arm trajectory simulation, with a remote service for allowing access control and arbitration in the use of robots as a shared service. This software allows the design of trajectories in robot and Cartesian coordinate spaces in a simple and convenient way for the user. The service allows the execution of said trajectories whenever the robot is available. Robotic arms ED-RobotAnno and ROS-RobotAnno are presented as use cases for this service. Concepts such as closed-loop motor control or direct robot kinematics are abstracted from the user, allowing the creation of unsupervised learning iterations of closed-loop trajectories or the creation of datasets for supervised training. Moreover, the servitization is based on a heterogeneous ecosystem composed of microservices that use different platforms/languages to provide a novel Web experience to users, while still being flexible to allow easy addition of new robotic arms. © ICST Institute for computer Sciences, Social Informatics and Telecommunications engineering 2025.

Speech separation aims to equip machines with the human ability of selective listening, i.e. to focus attention on specific information in spoken communication. Studies have shown that the language spoken in a cocktail party scenario matters. While the development of speech separation models can leverage extensive databases, for the majority of languages only very limited data is available. This work presents the very first study on speech separation for low-resource languages. We choose blind source separation as the task to be studied and analyze three strategies to overcome the data scarcity of two low-resource languages from the GlobalPhoneMS2 database. We show that data from other languages can be used to develop models that work for low-resource languages. Finetuning additionally boosts the performance, and training on multiple languages increases both performance and robustness. We show that dynamic mixing in the development helps to find a trade-off between performance and development time. © 2025 IEEE.

Internet of Things (IoT) devices have become increasingly ubiquitous with applications not only in urban areas but remote areas as well. These devices support industries such as agriculture, forestry, and resource extraction. Due to the device location being in remote areas, satellites are frequently used to collect and deliver IoT device data to customers. As these devices become increasingly advanced and numerous, the amount of data produced has rapidly increased potentially straining the ability for radio frequency (RF) downlink capacity. Free space optical communications with their wide available bandwidths and high data rates are a potential solution, but these communication systems are highly vulnerable to weather-related disruptions. This results in certain communication opportunities being inefficient in terms of the amount of data received versus the power expended. In this paper, we propose a deep reinforcement learning (DRL) method using Deep Q-Networks that takes advantage of weather condition forecasts to improve energy efficiency while delivering the same number of packets as schemes that don’t factor weather into routing decisions. We compare this method with simple approaches that utilize simple cloud cover thresholds to improve energy efficiency. In testing the DRL approach provides improved median energy efficiency without a significant reduction in median delivery ratio. Simple cloud cover thresholds were also found to be effective but the thresholds with the highest energy efficiency had reduced median delivery ratio values. © 2025, CC BY.

This paper presents a Python-based Nornir framework for automating network device hardening in multi-vendor environments, addressing critical gaps in scalability and interoperability. Unlike existing single-vendor solutions, our method enforces CIS benchmarks across Cisco, Juniper, and Fortinet devices, achieving an 82.18% reduction in hardening time compared to prior automation tools and a 99.99% improvement over manual techniques. By leveraging Nornir’s multi-threading and vendor-agnostic inventory management, the framework ensures consistent security policies while eliminating configuration errors. Experimental results across 18 heterogeneous devices demonstrate its efficiency, with full hardening completed in 44 s (95% CI [43.8, 44.1]). This work provides enterprises with a scalable solution to rapidly secure complex networks against evolving threats, bridging the gap between compliance standards and real-world deployment. © The Author(s) 2025.

Optical coherence tomography (OCT) scanning is crucial for the diagnosis of widespread ophthalmic diseases. Traditionally, experts manually identify diseases and biomarkers from OCT scans. Recently, modern medical imaging practices have increasingly utilized deep learning techniques to speed up and improve diagnostic accuracy in ophthalmology. However, obtaining accurately labeled datasets is a significant challenge in medical imaging due to the expertise required for precise annotation by trained professionals. This article presents a novel method, named OBoctNet, with a new two-stage training strategy to improve the identification of ophthalmic biomarkers using OCT scans from the OLIVES dataset, which contains only 12% labeled data. This approach leverages a robust methodology that effectively uses labeled and unlabeled data to enhance biomarker identification accuracy, achieving a cumulative performance increase of 23% across 50% of the biomarkers when compared to the previous studies. To better identify biomarkers, the OBoctNet employs an active learning strategy that uses unlabeled data and dynamically ensembles models based on their performance within each experimental setup. Additionally, the usage of Gradient weighted Class Activation Mapping (GradCAM) helps identify regions of interest associated with relevant biomarkers, enhancing interpretability and transparency for potential clinical adoption. © The Author(s) 2025.

Crop yield prediction is a significant area of precision agriculture. In this paper, we propose a crop yield prediction framework named FLyer, based on federated learning and edge computing. In FLyer, the soil and environmental data are locally processed inside the edge servers, and the model parameters are transmitted between the edge servers and the cloud with encrypted gradients. LSTM is used as the local and global models for data analysis. As the LSTM model can capture the temporal dependencies and hold the sequential nature of the data, we use LSTM in FLyer. By encrypting the gradients, the gradient information leakage ratio is reduced, and data privacy is protected. For gradient encryption, we use AES-256, and for data encryption during local storage we use RSA and AES-256. The results demonstrate that FLyer diminishes the latency by 39% and energy consumption by 40% than the conventional edge-cloud framework respectively. The experimental results show that the global model in FLyer achieves above 99% accuracy, precision, recall, and F1-score in crop yield prediction. The results also present that the local models also achieve >94% accuracy in crop yield prediction. © 2020 IEEE.

A major development in medical imaging diagnosis is the use of pretrained Convolutional Neural Network (CNN) models for brain tumour classification. This study uses pretrained CNN EfficientNetB3, ResNet50, and VGG19, to explore the crucial field of early brain tumour identification. The dataset used in the research consists of 7023 brain MRI images, which are divided into 2000 validation images, 1311 testing images, and 3712 training images. After preparing the data, we want to see which CNN designs work best for sorting images of gliomas, meningiomas, no tumors, and pituitaries into different groups. The study shows how important it is to find brain tumors early and how we can make brain imaging tests more accurate and helpful for diagnosing them. The EfficientNetB3 model is the best and wins with remarkable 99% accuracy. The results show the good and bad points of different models and give important information to help improve skills in diagnosing using neuroimaging.

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.
