Energy-Efficient Cell Association and Load Balancing for Low Battery Users in Heterogeneous Cellular Networks
Published 2025“…However, the offloading of users through conventional cell association schemes may not guarantee improved load balancing along with the energy efficiency (EE) of critical users such as user equipment (UE) with low battery power. This paper proposes improved cell association schemes based on the battery levels of UE and Deep Q-learning (DQL) to achieve load balancing and to decrease the power consumption of Low Battery Users (LBUs). …”
