An Energy Minimization Algorithm for Cooperative Spectrum Sensing
Résumé
We introduce an algorithm minimizing the consumed energy of a cooperative spectrum sensing-based cognitive radio network. The energy is minimized, while satisfying requirements for primary user protection and for secondary user data rate simultaneously, with respect to the powers for transmitting on control and data channels, the number of reported bits, and the thresholds of the global sensing test. Control and data channels are assumed not to be error-free. Simulation results
finally confirm our claims.
