Abstract

This paper proposes a new metric for performance analysis of the method entitled Spectrum Harvesting with ARQ Retransmission and Probing (SHARP), an underlay cognitive radio network (CRN) technique, i.e. the delay within the primary user transmissions. This variable depends on the operating region, channel utilization and data rate. The influence in primary transmissions is analyzed and mathematical results present conclusions about the impact in the effective primary user transmission time.
