 The w-iLab.t wireless testbed, part of the iMinds technical research centre iLab.t (http://ilabt.iminds.be), allows flexible testing of the functionality and performance of wireless networking protocols and systems in a time-effective way, by providing hardware and the means to install and configure firmware and software on (a selection of) nodes, schedule automated experiments, and collect, visualize and process results. Thanks to an in-house designed hardware control device, unique features of the testbed include the triggering of repeatable digital or analog I/O events at the sensor nodes, real-time monitoring of the power consumption, and battery capacity emulation.

At a first location, the "w-iLab.t Office" consists of a wireless Wi-Fi (IEEE 802.11a/b/g) and sensor network (IEEE 802.15.4) testbed infrastructure, deployed across three 90 m x 18 m floors of the iMinds office building in Ghent, Belgium. At 200 places throughout the office spaces, meeting rooms and corridors, wireless hardware is mounted to the ceiling.

In Zwijnaarde, Belgium, located approximately 5 km away from the "w-iLab.t Office", a second location is equipped with another 60 wireless nodes, with IEEE 802.11a/b/g/n, IEEE802.15.4 and IEEE802.15.1 (Bluetooth) interfaces. The location also hosts software defined radio platforms (USRP) and spectrum scanning engines developed by imec. The participant to this session will learn about the high-level characteristics of w-iLab.t and will learn where to find detailed information on the testbed. As most of the cognitive devices are located in the Zwijnaarde environment, a hands-on session will teach the participants how to run experiments in w-iLab.t Zwijnaarde using the OMF tools (http://mytestbed.net/).

More specifically, the participants will reserve nodes, schedule a cognitive radio experiment involving USRP devices and/or imec sensing nodes, and collect results. Participants will also learn how different solutions can be compared using the CREW benchmarking framework.
