Through extensive simulations, the energy efficiency of DUDe systems is evaluated under various scenarios, such as different UE densities, Base Stations (BSs) configurations, and traffic patterns. The simulation results indicate that the proposed DUDe system can achieve significant energy savings compared to traditional centralized 5G systems. The impact of various parameters on energy efficiency is also analyzed, providing guidelines for designing energy-efficient DUDe systems. The paper emphasizes the significance of energy-efficient design in 5G networks, as it can significantly reduce the operational costs and carbon footprint of the network.1 aKatsigiannis, Chrysostomos-Athanasios1 aTsachrelias, Konstantinos1 aKokkinos, Vasileios1 aBouras, Christos1 aGkamas, Apostolos1 aPouyioutas, Philippos  uhttp://telematics.upatras.gr/telematics/publications/energy-efficiency-analysis-dude-5g-networks
