Performance Evaluation of Software-Defined Wireless Networks in IT-SDN and Mininet-WiFi

Abstract

In this paper, we compare the performance of IT-SDN framework and Mininet-WiFi OpenFlow Network Emulator for Software-Defined Wireless Networks. The topology consists of a number of source nodes generating traffic towards a sink node. The controller sets up flow rules for the packets, following which the switches route the wireless traffic. The communication between the controller and the switches is governed by the underlying southbound protocol. The performance of IT-SDN and Mininet-WiFi for the stated network scenario was measured using the metrics: end-to-end delay, throughput, packet delivery ratio and control overhead. The results show that IT-SDN outperforms Mininet-WiFi in terms of the above mentioned metrics for the given wireless network scenario.
