Short testbed description

LOG-a-TEC is an outdoor experimental facility supporting cognitive radio networking experimentation in ISM and TV bands. The testbed consists of several clusters of wireless sensor nodes located in the municipality of Logatec, Slovenia and at the Jožef Stefan Institute campus. Clusters in the Logatec municipality cover approximately 350.000 m² of public space that includes the city center and an industrial zone.

Example experiments

Various experiments can be performed using the LOG-a-TEC infrastructure, for example:

• Investigating different RF interference detection techniques, e.g. distributed vs. centralized detection.
• Exploring different interference mitigation techniques, such as adaptive power control.

Access information

LOG-a-TEC is accessible via a web-interface. Experimenters can install pre-defined firmware on one or more sensor nodes, receive status information, download experiment traces, and interact with individual nodes during an experiment. Also custom firmware can be installed but needs to first be approved. Before running an experiment, the GRASS-RaPlaT tool can be used for simulation. The same tool can be used later to visualize the results of an experiment.
