WhoAmI: Personal Information Sharing Application over WiFi and WiFi Direct

WiFi-NC : WiFi Over Narrow Channels

The quest for higher data rates in WiFi is leading to the development of standards that make use of wide channels (e.g., 40MHz in 802.11n and 80MHz in 802.11ac). In this paper, we argue against this trend of using wider channels, and instead advocate that radios should communicate over multiple narrow channels for efficient and fair spectrum utilization. We propose WiFi-NC, a novel PHY-MAC desi...

SWISH: Secure WiFi sharing

The fast increase of mobile Internet use motivates the need for WiFi sharing solutions, where a mobile user connects to the Internet via a nearby foreign network while its home network is far away. This situation creates security challenges which are only partially solved by existing solutions like VPNs. Such solutions neglect the security of the visited network, and private users or organizati...

Visualizing Wifi using the Wifi Camera

These images were created using a " Wifi Camera " custom designed by Somlai-Fischer, Sjölén and Haque (information available at ). It makes a use of a directional 2.4Ghz wifi antenna mounted on servos scanning an environment at varying resolutions, measuring signal strength of all present networks to generate an image of the wifi " view " of the space. A ...

WiFi-Direct Simulation for INET in OMNeT++

Wi-Fi Direct is a popular wireless technology which is integrated in most of today’s smartphones and tablets. This technology allows a set of devices to dynamically negotiate and select a group owner which plays the role access point. This important feature is the strength of Wi-Fi Direct and makes it more and more widely used in telecommunications networks. In this paper, we present the implem...
