Performance evaluation of SDN WLAN architecture

This article focuses on mobility of stations under 802.11 standards, with use of Software-Defined Networking (SDN). Lately, there are several SDN-based solutions for seamless handover. These solutions typically use separate control channels to utilize the wireless part of network. In our work, we demonstrate high performance of SDN WLAN architecture under real word test scenarios. Our common control channels solution extends the OpenFlow protocol. Our proposed method is notably improving performance of network architecture in next topics: network scalability, security and parallelly it allows delay critical scenarios to be delivered smoothly including seamless handover.
