5G Network: techniques to Increase Quality of Service and Quality of Experience

Abstract

– The rapid growth of interconnected networks and devices inevitably causes the rise of traffic demand and thus pushes the technologies like long-term evolution-Advanced (LTE-A) and mobile multihop relay WiMAX networks technology to move into the fifth-generation (5G). The 5G network was envisioned to be built to encounter the fundamental challenges of quality of services in existing networks, such as allowing higher data rates, enhanced end-user quality of experience, reduced end-to-end latency, lower energy consumption, and higher traffic capacity. In order to satisfy and achieve the vision of the 5G network, extensive debates are in progress about the numerous techniques to be adapted. The objective of this study is to analyze various techniques for 5G networks to achieve the high enhance Quality of Service (QoS) and Quality of Experience (QoE) for users. Moreover, this paper also discussed several combinations of techniques for the upcoming 5G network, such as mmWave with Massive MIMO, D2D with SDN, D2D with mmWave, and D2D with Machine-to-machine communication and NFV and SDN hybrid. This study will be a significant endeavor in choosing possible techniques for 5G networks and further investigating various combinations of such techniques for future works. To make suitable techniques for the emerging 5G network, guidelines and challenges are highlighted to modify the existing techniques.
