Integration of Software-Defined Network and Fuzzy Logic Approaches for Admission Control in 5G Wireless Networks: A Fuzzy-Based Scheme for QoS Evaluation

The Fifth Generation (5G) network is expected to be flexible to satisfy user requirements and the Software-Defined Network (SDN) with Network Slicing will be the constructive paradigm for admission control. The Quality of Service (QoS) is influential point in the 5G wireless networks. In this paper, we propose a Fuzzy-based scheme to evaluate the QoS considering three parameters: Slice Throughput, Slice Delay and Slice Loss. We carried out the simulation for evaluating the performance of our proposed scheme. From simulation results, we conclude that the considered parameters have different effect on the QoS performance. When Slice Throughput (ST) is increasing, the QoS parameter is increased. But, when Slice Delay (SD) and Slice Loss (SL) are increasing, the QoS is decreased.
