Utilization Based Load Balancing Algorithm For Handover Reduction In 5G Networks

Abstract

The implementation of a load balancing algorithm involves distributing the load from congested small cells to less burdened ones within the network, taking into account mobility parameters. The traditional load balancing algorithms only considers the edges of the devices (UEs) when it comes to the offloading process. The proposed algorithm considers both the non-edge and edge-UEs for minimizing the load on the small cells. Subsequently, it relocates high-speed UEs to the underutilized Macrocell and slower-moving UEs to nearby small cells. The algorithm relies on categorizing UEs into fast, slow, and very slow groups to make optimal handover decisions. Simulations have demonstrated that this approach results in the fewest handovers and the highest throughput.
