MSc thesis, MPS, Ljubljana, Slovenia.
Some of the concepts and methods for more ecient utilisation of radio spectrum dependon better knowledge of the changing availability of radio resources with time and location,which can be provided by various spectrum sensing approaches. This thesis presentsthe design and implementation of a spectrum sensing testbed, based on low-cost and lowcomplexityVESNA platform, aimed to support experimental-driven research in cognitiveradio and networking.
erent device types by using a very simple propagation model.
The thesis presents an example of planning and executing a spectrum sensing experimentin the deployed testbed. In order to support easier and more correct experiment planning,radio link measurements have been performed to determine the coverage areas of individualtransceivers. Next, an example experiment, consisting of an emulated interference avoidancescenario, has been planned and performed with a preselected set of nodes. The obtainedexperimental results are in line with the expected values, proving the correct functioning ofthe testbed.
