Special Issue Information

Dear Colleagues,

Unmanned aerial vehicles (UAVs), commonly known as drones, have witnessed remarkable advancements in recent years and have become valuable tools in various applications. From aerial photography and surveillance to package delivery and infrastructure inspection, drones offer unprecedented capabilities and efficiency. However, the widespread deployment of drones also raises concerns about their environmental impact, particularly in terms of energy consumption and carbon emissions.

This Special Issue aims to explore the field of green communications and networking for drones, focusing on novel techniques, technologies, and strategies to enhance their energy efficiency, reduce their carbon footprint, and promote sustainable operation. We invite researchers, academics, and industry experts to contribute original research articles, review papers, and case studies on the latest advancements in this emerging field.

Topics of interest include but are not limited to:

  • Energy-efficient communication protocols and algorithms for drones;
  • Green networking architectures and infrastructures for drone systems;
  • Power management and optimization techniques for drone platforms;
  • Renewable energy harvesting and power supply solutions for drones;
  • Energy-aware routing, scheduling, and resource allocation in drone networks;
  • Energy-efficient data processing and storage mechanisms for drone applications;
  • Adaptive and autonomous energy management for drone swarms;
  • Integration of drones with green communication technologies, such as the Internet of Things (IoT) and 5G/6G networks;

In this study, a reconfigurable intelligent surface (RIS)-assisted wireless-powered mobile edge computing (WP-MEC) system is proposed, where a single-antenna unmanned aerial vehicle (UAV)-mounted cloudlet provides offloading opportunities to K user equipments (UEs) with a single antenna, and the K UEs can harvest the energy from the broadcast radio-frequency signals of the UAV. In addition, rate-splitting multiple access is used to provide offloading opportunities to multiple UEs for effective power control and high spectral efficiency. The aim of this paper is to minimize the total energy consumption by jointly optimizing the resource allocation in terms of time, power, computing frequency, and task load, along with the UAV trajectory and RIS phase-shift matrix. Since coupling issues between optimization variable designs are caused, however, an alternating optimization-based algorithm is developed. The performance of the proposed algorithm is verified via simulations and compared with the benchmark schemes of partial optimizations of resource allocation, path planning, and RIS phase design. The proposed algorithm exhibits high performance in WP-MEC systems with insufficient resources, e.g., achieving up to 40% energy reduction for a UAV with eight elements of RIS. Full article

Unmanned aerial vehicle (UAV)-assisted simultaneous wireless information and power transfer (SWIPT) systems have recently gained significant attraction in internet-of-things (IoT) applications that have limited or no infrastructure. Specifically, the free mobility of UAVs in three-dimensional (3D) space allows us good-quality channel links, thereby enhancing the communication environment and improving performance in terms of achievable rates, latency, and energy efficiency. Meanwhile, IoT devices can extend their battery life by harvesting the energy following the SWIPT protocol, which leads to an increase in the overall system lifespan. In this paper, we propose a secure UAV-assisted SWIPT system designed to optimize the secrecy energy efficiency (SEE) of a ground network, wherein a base station (BS) transmits confidential messages to an energy-constrained device in the presence of a passive eavesdropper. Here, we employ a UAV acting as a helper node to improve the SEE of the system and to aid in the energy harvesting (EH) of the battery-limited ground device following the SWIPT protocol. To this end, we formulate the SEE maximization problem by jointly optimizing the transmit powers of the BS and UAV, the power-splitting ratio for EH operations, and the UAV’s flight path. The solution is obtained via a proposed algorithm that leverages successive convex approximation (SCA) and Dinkelbach’s method. Through simulations, we corroborate the feasibility and effectiveness of the proposed algorithm compared to conventional partial optimization approaches. Full article
