Solar Energy Harvesting To Optimise The Power Constraints In 5G Systems

Abstract

In recent years, a number of studies have focused on optimizing resource allocation and energy cooperation; however, prior to this time, these two topics were rarely discussed together in the same study. This paper analyzes the topic while keeping in mind both the enormous potential of RE and the difficulties that are associated with resource distribution. We take into consideration the downlink transmission model in millimeter-wave BSs, with each BS being powered by sources of renewable energy (RE), in addition to smart grids, and we optimize for overall system energy efficiency (EE). Within the confines of the constraints imposed by the transmit power of the BSs, the quality of service requirements of the UEs, and the collection energy that is available, an investigation into the problem of resource optimization was carried out with the intention of maximizing the total system energy efficiency (EE) by optimizing user association, power allocation, and energy cooperation. This was done with the intention of maximizing the total system energy efficiency (EE). © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
