Beacon-enabled cognitive access for dynamic spectrum access
In dynamic spectrum access networks, the unused licensed spectrum used by primary users (PU) is opened to unlicensed secondary users (SU) for improving spectrum efficiency. We design a simple time-based threshold policy for collective protection of PUs, enabled by an out-of-band channel.

Spectrum Hole Geolocation for Database-Driven IoT-Enabled Dynamic Spectrum Access
The effective realization of dynamic spectrum access (DSA) subsumes that, when a secondary terminal seeks a vacant band, the geolocation of the candidate spectrum hole coincides with the position of the terminal.
