Performance Analysis of Various SDN Controllers with Different Network Size in SDWN

Software-defined Wireless Networking (SDWN) is the next generation of wireless networks. It performs the same Software Defined Networking (SDN) operation by decoupling the control plane from the data plane on the network device and transfers it to the controller, to provide easy control and centralized management to the network. Since the controller represents the most important part of the software-defined network architecture. In this paper, we examine the performance of four SDN controllers: POX, RYU, Open Daylight (ODL), and Open Network Operating System (ONOS) in different sizes of the emulated wireless network in terms of the network parameters such as throughput, delay, jitter and packet loss using the Mininet WIFI platform. Tests of this experiment help to choose the appropriate controller according to various parameters and states of the wireless network.
