Geolocation of Vacant Bands for Dynamic Spectrum Access via Non-Cooperative Spectrum Sensing

Accurate geolocation of vacant bands is an essential metric to timely and secure channel use in dynamic spectrum access systems. Non-cooperative spectrum sensing (NCSS) offers a promising solution by directly linking sensing decisions to sensor locations. This study employs NCSS within a database-driven internet of things framework, where scattered sensors perform individual detections and their positions are gathered via Voronoi-based spatial interpolation. Results show that high geolocation accuracy and low variance can be achieved even under unfavorable propagation conditions, supporting efficient and reliable spectrum use.
