Today's world more and more comprises WLAN capable devices. These can be used to set up so-called ad-hoc networks which enable multi-hop communication with no explicitly required fixed infrastructure. In this context numerous applications in military, educational, touristic or gaming scenarios arise: Wireless and distributed voice-over-IP, slideshow and chat applications as well as multiplayer games can become highly attractive as, by use of ad-hoc networks, they can be provided wherever WLAN devices gather. We in this demonstration show fully operational implementations of these applications, which run on a set of Windows and Linux notebooks forming a small ad-hoc network.
