Abstract
The knowledge of the statistical characterization of
the primary user activity can make more efficient the spectrum
selection techniques, which are a key technology to improve the
Cognitive Radio (CR) systems performance. In order to provide
this kind of primary user information, Radio Environment Maps
(REM) data bases has been proposed. This paper presents a
REM-based Real Time Testbed designed to validate and exploit
the dynamicity of the REM data base to improve the
performances of the Radio Resource Management (RRM)
algorithms in the context of cognitive radio. The implemented
testbed is a flexible HW/SW tool able to use spectrum
measurements in licensed bands and validate the Cognitive Radio
performance of the secondary users, without causing any
interference on these primary users. In particular, the RRM
strategy under study in the testbed envisages the optimization of
the spectrum selection policy when secondary users, with
different service profiles, access opportunistically a set of
channels during the inactivity periods of primary users. The
selection is done taking as input the statistical characterization of
the primary user activity, which will be stored in the REM data
base, and the secondary user service profiles.
