With smart devices and high-speed networks advancing rapidly, the Internet of Things (IoT) is widespread across sectors. However personal privacy becomes a concern within the vast expanse of IoT data in this more convenient era. Access control stands out as a pivotal technology for safeguarding data integrity, ensuring authorized user-exclusive data access. Attribute-based access control (ABAC), a traditional access control model, offers the key benefit of allowing access control based on multiple attributes for enhanced flexibility. However, ABAC model faces drawbacks like single points of failure and limited transparency due to its single-server focus, potentially leading to data vulnerabilities. As a promising technology, blockchain provides novel approaches for designing new access control models. In this regard, we propose a blockchain-based security access control (BBSAC) model. On the basis of ABAC, the model uses blockchain technology to realize the decentralization, automation and fine-grained access control of Internet devices. At the same time, the trust value is used as an additional attribute to evaluate the reputation of different users, and the trust value is updated after each interaction to assign different access rights to different users, thereby realizing dynamic rights management. Theoretical analysis and experimental simulation results show that the model can maintain high throughput under a large number of requests while ensuring fine-grained and dynamic access control.

Micro-mobility, such as electric scooters and bicycles, has set a trend in recent years. This low-speed mode of transport, widespread and getting connected, represents a significant paradigm shift in contemporary transportation dynamics. To integrate these low-speed types of transport within the Intelligent Transport System (ITS), the paper proposes the use of the Vehicular Ad-Hoc Network (VANET) communication model within the Internet of Vehicles (IoV) using the IEEE 802.11p short-range communications standard. We propose a geofencing model that allows an optimal control of micro-mobility entities speeds in limited geographical areas and we simulate several use cases which can take place within our geofencing model. In addition, an energy saving approach is proposed given the presence of several roadside units (RSUs) in geofencing zones.

This paper presents a novel approach to integrate heterogeneous agents working in an agricultural scenario. We explore a multi-agent system, comprising both agricultural robots (AgBots) and human operators, that handles various tasks such as fruit picking and crop monitoring in row-planted environments like vineyards. Our key contribution is a distributed motion control strategy for collision avoidance, ensuring agents maintain safe distances from each other and crop rows without requiring direct communication or central coordination. The effectiveness of our approach is validated theoretically and demonstrated through numerical simulations in a Gazebo-based environment.

The increasing global interest in renewable energy-based power systems is fuelled by their abundance and environmentally friendly characteristics. Hybrid Renewable Energy Systems (HRES) represent a novel development, integrating multiple sustainable sources like wind turbines, solar photovoltaic (PV) systems, and other renewables like ocean, wave, and geothermal energy. Integrating multiple renewable energy sources such as solar, wind, hydro, and biomass and energy storage systems as a backup for the reliable power supply has been considered. To ensure uninterrupted power supply to the growing community and industrial sector, proper synchronization and management of alternative power sources are imperative through an energy management system. The hybrid energy system optimizes power-generating module quantities and sizes, including PV systems, wind turbines, batteries, and diesel generators, while meeting load requirements. Implemented in MATLAB Simulink, alongside a full model of the hybrid renewable energy systems, simulation results illustrate the effectiveness in maintaining voltage and frequency within acceptable ranges during diverse operating conditions. In conclusion, this manuscript offers a comprehensive study on the optimization and control of a solar-wind hybrid renewable energy system, serving as a valuable tool for designing and operating such systems in remote and islanded communities.
