A new SDN-based framework for wireless local area networks

Nowadays wireless networks are becoming important in personal and public communication andgrowing very rapidly. Similarly, Software Dened Network (SDN) is an emerging approach to over-come challenges of traditional networks. In this paper, a new SDN-based framework is proposedto ne-grained control of 802.11 Wireless LANs. This work describes the benets of programmableAccess Points. The proposed framework is evaluated on a prototype. We show that this architectureallows us to react to application needs, adjust network conguration for a priority application, detectnetwork problems, and improve the user experience of the network. Our architecture relies on theIEEE 802.11 standard, and exploits it to collect information from the stations.
