Access control with ONOS controller in the SDN based WLAN testbed

Nowadays, software-defined networking (SDN) has attracted a lot of interest. Therefore, many research works have introduced the new concepts and architecture to SDN-based network. However, most of existing research studies in wireless network area mainly introduce the theoretical concepts and face a difficulty to implement on the testbed. In addition, useful network applications with SDN controller is essential to improve SDN-based network. In order to overcome these limitations, we propose the access control mechanism on the SDN-based network by using SDN controller. Moreover, we introduce the system architecture and testbed for the proposed scheme. Therefore, we guarantee quality of service (QoS) for the high-priority user group and manage the WLAN AP dynamically.
