Towards a scalable and near-sighted control plane architecture for WiFi SDNs.

ABSTRACTNot much is known today about how to reap the SDN benefits in WiFi networks-a critical use case given the increasing importance of WiFi networks. This paper presents AeroFlux, a scalable software-defined wireless network, that supports large enterprise and carrier WiFi deployments with low-latency programmatic control of fine-grained WiFi-specific transmission settings. This is achieved through AeroFlux's hierarchical design. We report on an early prototype implementation and evaluation, showing that AeroFlux can significantly reduce control plane traffic.
