iMinds iLab.t w-iLab.t

The w-iLab.t generic wireless testbeds consist out of embedded PCs that are equipped with multiple wireless interfaces, including Wi-Fi a/b/g/n, sensor nodes with 802.15.4 interfaces and Bluetooth. It is up to the experimenters to determine which interfaces will be used, and what software/firmware is installed on the embedded PCs and/or sensor nodes. This means that w-iLab.t users are able to set up experiments that are e.g. evaluating Wi-Fi mesh protocols by configuring some of the w-iLab.t nodes as mesh backbone routers, and other nodes as mesh clients, or, may choose not to use Wi-Fi interfaces but instead evaluate the energy consumption of sensor nodes that are for example running medium access protocols optimized for energy efficiency, or may execute IoT scenarios such as making available measurements from a sensor cloud across the internet.

w-iLab.t is deployed at two locations. w-iLab.t Office (a.k.a. "wilab1") provides a generic, in-building wireless testbed with 200 sensor nodes and 400 IEEE 802.11 a/b/g interfaces. In addition, w-iLab.t Zwijnaarde (a city close to Gent, a.k.a. "wilab2") provides a controlled test environment with an additional 60 fixed nodes and 15 mobile nodes. Each fixed and mobile node includes a 802.15.4 sensor node, and two WiFi a/b/g/n interfaces; some nodes are equipped with an 802.11ac interface. Additionally there are a number of software defined radios and spectrum sensing components available.

w-iLab.t can be used to test new hardware (e.g. it is possible to plug in new sensor nodes) and software (e.g. new protocols for routing or interference avoidance; new sensor applications, etc.).

The photo below provides a view on the w-iLab.t Zwijnaarde testbed environment, i.e. the newest and most used testbed. The black devices mounted on the metal rods are the embedded PC's. The grid lines on the floor are used to correct the positioning of the mobile robots.
