Improving QoS by SDN based Handover Management in 5G Networks

Abstract

The purpose of this article is to enhance handover procedure in small cell based Ultra-Dense 5G Networks. The large number of small cells in dense heterogeneous 5G networks may result in unnecessary, frequent, and back and forth handovers with additional problems related to increased delay and total failure of handover process. Additionally, due to the separation of control and data signaling in 5G technology, the handover operation must be executed in both tiers. In this article we propose an SDN based approach to enhance handover mechanism.

The simulated results for E2E delay and throughput are compared with mininet based emulator The proposed strategy reduces the handover delay and failures by 36 and 24 percent respectively.
