Abstract
Frequency band in a spectrum consisting of multiple channels are opportunistically accessed by the secondary users (SUs) is studied. The channels allocated to the primary users (PUs) with license are also temporarily utilized by the unauthorized secondary users during the idle period of PUs. The state of each channel is modeled as a discrete-time Markov Chain process. Collisions developed among the SUs during sensing or accessing the same channel in same time slot, are efficiently handled by extending the existing myopic sensing policies. Assuming the number of channels greater than and equal to the number of SUs, the proposed method claims that collisions can be reduced, without using more than the desired number of channels rather than by increasing the weights assigned to the representatives of the dominating sets of SUs.
