A groundbreaking model called GREENSKY has been developed by researchers from the University of Missouri-Kansas City, School of Computing and Engineering, along with independent researchers. This model aims to boost the energy efficiency and operational time of Unmanned Aerial Vehicles (UAVs) in cellular networks. In areas without traditional network infrastructure, such as rural or disaster-affected regions, UAVs play a crucial role. GREENSKY optimizes UAV charging behavior by utilizing both static ground base stations and mobile supercharging stations. This optimization enables longer operational periods without the need for frequent recharging.
By incorporating Mixed Integer Linear Programming, the GREENSKY model streamlines the recharging and routing processes for UAVs. This optimization maximizes flight duration while minimizing energy consumption. The model strategically utilizes existing cellular base stations as opportunistic charging points, reducing travel distances for recharging. As a result, UAVs can operate for longer durations with less energy consumption. Research results have shown that GREENSKY can achieve a significant reduction in energy consumption, surpassing traditional heuristic solutions by 9.1%.
Lead researcher Pratik Thantharate emphasizes the significance of the GREENSKY model in making UAV networks more sustainable and efficient. By optimizing the recharging process, the operational time of UAVs can be significantly extended. This is critical for ensuring continuous and reliable service in remote or critical areas. Additionally, the development of this optimization model not only enhances the efficiency of UAV networks but also drives innovation in energy management for UAVs serving as aerial base stations.
The introduction of the GREENSKY model promises not only improved service reliability but also contributes to the advancement of energy-conscious technology deployments in 5G and beyond. As UAVs continue to be integrated into various industries, this model offers a more efficient and cost-effective approach to UAV energy management and task execution. By leveraging static and mobile charging stations effectively, the GREENSKY model sets the stage for a smarter and more robust framework for future aerial communication networks. This approach not only enhances connectivity in underserved regions but also leads the way for energy-efficient technology deployments in the future.
