(事前公開アブストラクト) We have observed the popularity of Wi-Fi technology on a vast number of electronic devices, each of which generally has one physical Wi-Fi card. The Wi-Fi virtualization technology, which is software-based, can transform a physical Wi-Fi interface into several virtual ones on a Wi-Fi device. As a result, with the Wi-Fi virtualization, the device practically has multiple radios that can play different roles (e.g., either the client or access point modes). That potentially enables a wide range of new applications, which ultimately push the Wi-Fi adoption further. In this work, we first discuss the uses of Wi-Fi virtualization including aggregating APs? backhaul bandwidth, sharing Internet connections, etc. Secondly, we present an extensive evaluation of a virtual Wi-Fi system in comparison to the physical one aiming to show the advantages of Wi-Fi virtualization. The results show that in a typical scenario the virtual Wi-Fi interface's performance is similar to the physical Wi-Fi's. |
