20.500.12556/RUL-167551 A heuristic approach to energy efficient user association in ultra-dense HetNets using intermittent scheduling strategies The ultra-dense deployment of pico cells in 5G heterogeneous networks (HetNets) has raised serious concerns regarding interference and energy consumption. Both industry and academia are focusing on enhancing network energy efficiency (EE) while maintaining satisfactory quality of service (QoS) levels. However, finding an optimal solution to NEE is very challenging, especially in ultra-dense HetNets. Here, a user association and power management algorithm is presented that follows a heuristic approach and aims to maximize EE while satisfying other network requirements. The proposed algorithm associates users based on criteria that consider the users’ EE and minimizes energy consumption by intermittently switching into sleep mode base stations with the highest impact on overall network EE. The performance of this solution is evaluated in a realistic multi-cell two-tier scenario considering both co-tier and cross-tier interference by comparing it with two other solutions: a heuristic approach based on standardized eICIC, and an optimization approach based on Lagrangian dual decomposition. The simulation results show that our solution outperforms benchmarking solutions in terms of EE, average user rate, and network throughput while minimizing energy consumption. 5G HetNet heterogeneous networks energy efficiency 5G HetNet heterogena omrežja energetska učinkovitost true false true Angleški jezik Slovenski jezik Članek v reviji 2025-02-27 13:10:39 2025-02-27 13:10:44 2025-06-30 11:44:21 0000-00-00 00:00:00 2024 0 0 Str. 1079-1088 iss. 17 Vol. 18 2024 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 621.39 1751-8628 10.1049/cmu2.12816 206870275 IET_Communications_-_2024_-_Dobruna_-_A_heuristic_approach_to_energy_efficient_user_association_in_ultra‐dense_HetNets_(1).pdf IET_Communications_-_2024_-_Dobruna_-_A_heuristic_approach_to_energy_efficient_user_association_in_ultra‐dense_HetNets_(1).pdf 1 AA5D6A177D085364E3B3231B6EC79E78 4de130fb56c6352ec8b45609fe65d9e91ad40b849c078db5070e796938bdf65f 2cd3e71c-f503-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200183 https://ietresearch.onlinelibrary.wiley.com/doi/10.1049/cmu2.12816 1 f41e8ae3-f502-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200182 Fakulteta za elektrotehniko 0 0 0
