Ethanol: Software defined networking for 802.11 Wireless Networks

Abstract

Wireless Networks have become ubiquitous and dense to support the growing demand from mobile users. To improve the performance of these networks, new approaches are required, such as context and service aware control algorithms, which are not possible on today's closed proprietary WLAN controllers. In this work, we propose Ethanol, a softwaredefined networking architecture for 802.11 dense WLANs. This paper describes the benefits of programmable APs, and proposes Ethanol, an architecture for network-wide control of QoS, user mobility, AP virtualization, and security on 802.11 APs. The proposal is evaluated on a prototype using off-the-shelf APs over three use cases.

Estimativa de Qualidade de Serviço em Estações Wi-Fi Utilizando Redes Neurais Recorrentes

“…Como sequência deste trabalho, pretendemos utilizar a função de regressão obtida em um algoritmo de controle automático executando em um controlador SDN, como o Ethanol [Moura et al 2015], de modo que ele possa definir a configuração dos APs que garanta a melhor QoS para as estações cliente. Também pretendemos realizar uma avaliação em um ambiente mais amplo e mais complexo, por exemplo considerando a mobilidade de estações e dispositivos com hardware heterogêneo.…”

A Software Defined Wireless Networking Approach for Managing Handoff in IEEE 802.11 Networks

“…In [21], a SDN architecture is proposed to obtain statistical data of the network usage, as well as information about the traffic load in each AP. This information is then used to choose the destination of AP during the handoff, aiming to improve the load balancing among nearby APs.…”

Software-Defined Wireless Mesh Networking: Current Status and Challenges

“…Additionally, it is proposed to include the 802.11 header into the list of headers that can be examined by OF. The authors in [34] propose an SDN architecture for dense WiFi deployments called Ethanol. The focus of their work is the definition of a WiFi capable southbound interface for getting and setting different parameters.…”
