SDN-Based Wireless Network Performance Evaluation

Abstract

Software-defined Networking (SDN) is a new paradigm that has been researched by many people because this is a Programmable Network. The separation of control plane and data plane in its network architecture makes the network devices easier to configure because of the centralized control system using the SDN controller. Research about SDN then evolved towards the wireless networks, and Software-defined Wireless Networking (SDWN) began to be researched. In this paper, we present a performance evaluation of SDN-based wireless network. Using 802.11g wireless standard, we simulated some scenarios through Mininet-WiFi and we examined the impact of background traffic while doing the scenarios. The result shows that the performance of the SDN-based wireless network with VoIP scenarios decrease compared to no background traffic given, with the increase of delay by 60.73%, the increase of jitter by 20.62%, the increase of packet loss by 0.03%, and the decrease of throughput by 31.44 when the given background traffics are 1 Mbps, 100 kbps, 40 Mbps, and 50 Mbps. The performance with the file transfer scenarios also decreases compared to no background traffic, with the increase of delay by 459.05%, the increase of packet loss by 0.043%, the decrease of throughput by 64.64% when the given background traffic is 24.09 Mbps. The SDN-based wireless network performance with the video streaming scenarios decrease compared to no background traffic, with the increase of delay by 175.88%, the increase of jitter by 45100.12%, the increase of packet loss by 0.58%, and the decrease of throughput by 46.35% when the given background traffic is 40 Mbps.
