In the Internet of Vehicle ecosystem, multi-access edge computing (MEC) enables mobile nodes to improve their communication and computation capabilities by executing transactions in near real-time. However, the limited energy and computation capabilities of MEC servers limit the efficiency of task computation. Moreover, the use of static edge servers in dense vehicular networks may lead to an influx of service requests that negatively impact the quality of service (QoS) of the edge network. To enhance the QoS and optimize network resources, minimizing offloading computation costs in terms of reduced latency and energy consumption is crucial. In this paper, we propose a cooperative offloading scheme for vehicular nodes, using vehicles as mobile edge servers, which minimizes energy consumption and network delay. In addition, an optimization problem is presented, which is formulated as a Markov Decision Process (MDP). The solution proposed is a deep reinforcement-based Twin Delayed Deep Deterministic policy gradient (TD3), ensuring an optimal balance between task computation time delay and the energy consumption of the system.

Smart cities have appeared as an essential paradigm, leveraging advanced technology and data-driven techniques to enhance residents' quality of life, drive economic growth, improve governance, and facilitate environmental sustainability. Promoting experimental testing of existing and emerging technologies in realistic smart-city-simulated environments is paramount for their development. OpenCyberCity, a smart city testbed developed at Virginia Commonwealth University, echoes this progress by incorporating smart functionalities such as smart buildings, traffic systems, manufacturing, data analytics, autonomous response systems, and microgrid infrastructure capabilities. This paper presents recent expansions and updates on the OpenCyberCity testbed, enabling further experimentation across various smart city domains, with the aim of improving energy conservation, transportation, building management, resilience, and sustainable infrastructure development.

Digital twins improve the performance of heavy equipment and decrease its operational costs. To be effective, they must run along decades of a real machine lifecycle. Ensuring coherence between a real machine and its digital twin over such a long period is a challenging task that has not yet been well-studied. This task involves preserving the design and operational data and periodic execution of digital twin software that processes such data. The circumstances of heavy equipment operation complicate the task. This paper considers the problem of digital twin data and software management in light of the unique challenges related to heavy equipment. It presents an experimental case study for running digital twins of mobile log cranes using a data model and a microservices-based architecture developed by the authors. The results demonstrate the capability of the architecture for running physics-based digital twins of heavy equipment in a heterogeneous execution environment consisting of local, edge, and cloud computing resources.

Virtual and augmented reality are currently enjoying a great deal of attention from the research community and the industry towards their adoption within industrial spaces and processes. However, the current design and implementation landscape is still very fluid, while the community as a whole has not yet consolidated into concrete design directions, other than basic patterns. Other open issues include the choice over a cloud or edge-based architecture when designing such systems. Within this work, we present our approach for a monitoring intervention inside a factory space utilizing both Virtual Reality (VR) and Augmented Reality (AR), based primarily on edge computing, while also utilizing the cloud. We discuss its main design directions, as well as a basic ontology to aid in simple description of factory assets. In order to highlight the design aspects of our approach, we present a prototype implementation, based on a use case scenario in a factory site, within the context of the EnerMan H2020 project.

Recent years have seen significant advancements in sensor-based pervasive and wearable activity recognition, primarily through the development of novel sensing modalities and the application of advanced machine learning algorithms. Despite this progress, the potential of impedance sensing in daily-life scenarios for pervasive and wearable activity recognition remains underexplored, particularly in contrast to its successful application in industrial and labor areas. Additionally, there is a lack of comprehensive studies on end-to-end optimization strategies from sensor to model, aimed at reducing both input and computational complexity of the neural network model, enabling it to not only run but also update efficiently on edge devices. This research project aims to bridge these gaps by investigating impedance sensing as a core technology for pervasive and wearable activity recognition in everyday environments and studying sensor-data-model co-optimization pipeline to enhance the performance and efficiency of these systems on edge devices.
