We present a cross-layer analysis of multi-stage spectrum sensing protocols used in multi-channel Opportunistic Spectrum Access (OSA) communication. By developing a novel analytical tool, we are able to assess the energy consumed by OSA communication. Furthermore, we present the relationship between the energy consumption of the multi-stage spectrum sensing protocol, the average throughput of OSA...
Multistage sensing is a novel concept that refers to a general class of spectrum sensing algorithms that divide the sensing process into a number of sequential stages. The number of sensing stages and the sensing technique per stage can be used to optimize the performance with respect to secondary user (SU) throughput and the collision probability between primary user (PU) and SU. So far, the impact...
