“…Simulation results show that the management achieves higher UEs energy efficiency, increases network throughput, and lower packet dropping of real-time flows. According to traffic circumstances and threshold delays for 4G and beyond, the author of the study [20] suggests adapting sleep patterns. Results lead to significant power savings.…”

5G Heterogeneous Network (HetNet) allows User Equipment (UEs) massive connections and various applications, which results in an exponential increase in the data traffic. This leads to massive overloading at co-tier and inter-tier levels, UE power inefficiency at the cell edge, and complexing Quality of Service (QoS) support. In this paper, we propose a scheme to solve the load balancing among Base Stations (BSs) while, enhancing power efficiency and guaranteeing QoS of UEs. The proposed heuristic scheme consists of three phases. The first phase addresses the UE's Discontinuous Reception (DRX) configuration parameters, the second phase evaluates overloading, and the third phase offloads the data from the overloaded BS to other BS. We have categorized the performance indicators, 1) User performance parameters (UPP) such as DRX power saving, packet drop rate, and end-to-end delay, 2) Network Performance Parameters (NPP) such as throughput. To validate, we design an analytical model based on a two-dimensional continuous-time Markov chain (2D-CTMC) and semi-Markov, and a simulator that validates the scheme performance. The results show that the proposed scheme enhances the performance in terms of UPP and the NPP.
