Title: Virtualising Wi-Fi Networks

Abstract: As users increasingly use mobile devices to connect to the Internet, mobile operators are deploying Wi-Fi access points to increase coverage and offload capacity. In popular locations, such as airports, shopping centres and cafés, infrastructure is however frequently managed by local businesses and operators are required to share the limited resources of access points. This talk will expose a wireless LAN virtualisation mechanism that guarantees fair distribution of resources among service providers, while maximising the network throughput. The proposed solution dynamically adjusts the contention parameters employed by the clients of virtual networks and results will demonstrate its effectiveness over different user distributions and traffic demands. Finally, practical implementation aspects will be discussed.
