We consider a cognitive radio setting in which the secondary user is an energy harvester with a finite capacity battery. The primary user operates in a time-slotted fashion. At the beginning of each time slot, the secondary user, aiming at maximizing its throughput, may remain idle or carry out spectrum sensing to detect primary activity. The decision is determined by the secondary belief regarding primary activity and the amount of stored energy. We formulate this problem as a Markov decision… CONTINUE READING
