Abstract:

This paper evaluates the role of federated satellite systems (FSSs) in enhancing unmanned vehicle-supported military medical evacuation (MEDEVAC) missions. An FSS integrates multiple satellite systems, thus improving imaging and communication capabilities compared with standalone satellite systems. A simulation model is developed for a MEDEVAC mission where the FSS control of an unmanned aerial vehicle is distributed across different countries. The model is utilized in a simulation experiment in which the capabilities of the federated and standalone systems in MEDEVAC are compared. The perform

Natural disasters often destroy and disrupt communication infrastructures that hinder the utilization of disaster applications and services needed by emergency responders. During these circumstances an implementation of a standalone communication system (SCS) that serves as an alternative communication platform for vital disaster management activities is essential.

Abstract:

The traditional standalone operational technology systems that control multiple mechanical systems on board a ship get increasingly integrated with modern information and communications technology (ICT)-related systems. These ICT systems that continuously become interconnected with operational technologies and systems include the Internet-of-Things (IoT), autonomous technologies and the internet with adequate bandwidth etc. The IoT typically employs numerous sensors and captures vast amounts of data, which is processed, transmitted and turned into trusted intelligence to the advantage of all p

Abstract:

Cyber threats are growing in scale and complexity, outpacing the capabilities of traditional security systems. Machine learning (ML) models offer enhanced detection accuracy but often rely on centralized data, raising privacy concerns. Federated learning (FL), by contrast, enables decentralized model training but suffers from scalability and latency issues. Hybrid AI models, which integrate ML and FL techniques, have emerged as a promising solution to balance performance, privacy, and scalability in cybersecurity. This systematic review investigates the current landscape of hybrid AI models, e

Abstract:

The spread of Internet of Things (IoT)-based healthcare systems has considerably enhanced real-time patient monitoring, but the performance of such systems largely relies on the integrity and accuracy of sensor data. Heartbeat sensors, although unavoidable, are prone to environmental noise, hardware degradation, and cyber threats, resulting in potential faults that can undermine medical decisions. Addressing these challenges, this paper proposes a novel self-adaptive sensor fault detection framework that leverages Federated Learning (FL) and Lightweight Transformer models.

Abstract:

The Industrial Internet of things (IIoT), the implementation of IoT in the industrial sector, requires a deterministic, real-time, and low-latency communication response for its time-critical applications. A delayed response in such applications could be life-threatening or result in significant losses for manufacturing plants. Although several measures in the likes of predictive maintenance are being put in place to prevent errors and guarantee high network availability, unforeseen failures of physical components are almost inevitable.

Abstract:

Vehicular Ad Hoc Networks (VANETs) have emerged as a critical component in intelligent transportation systems (ITS), enabling vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. However, the highly dynamic topology, high mobility, and low latency requirements of VANETs present significant challenges for ensuring reliable and efficient data transmission. Traditional machine learning models often struggle to adapt to VANETs’ real-time data processing needs and variable network conditions.

Abstract:

Wireless communication systems require electrical energy to operate and function. Whereas standalone applications require reliable power sources which can be realised by photovoltaic technology. Typically, photovoltaic cells and antennas are two separate devices. These devices compete for space in mobile or standalone systems, where available space is generally very limited. To address this issue, a combination of an antenna and a solar cell into a single device is needed. Integrating an antenna with a solar cell is challenging due to the importance of maintaining a compact, simple design whil

In digital audio systems, filters and equalizers are essential modules for audio improvement at the input and output stages. Due to their computational complexity, most audio tasks are processed with digital signal processors. Due to the fact that latency in audio systems is a critical specification and audio trends require higher sample rates, noise canceling, and bigger data sizes, having an independent high-resolution equalizer would reduce the computational power needed for audio systems.

Increased capacity, higher data rate, decreased latency, and better service quality are examples of the primary objectives or needs that must be catered to in the near future, i.e., fifth-generation (5G) and beyond. To fulfil these needs, cellular network design must be drastically improved. The 5G cellular network design, huge multiple-input multiple-output (MIMO) technology, and device-to-device communication are all highlighted in this comprehensive study. Hence, free-space optics (FSO) is a promising solution to address this field. However, FSO standalone is insufficient during turbulent w
