Energy Efficiency Analysis in Spectrum Sensing Cognitive Radio Network

Abstract

The spectrum scarcity problem is addressed by number solutions by various researchers in cognitive network field. The dynamic spectrum allocation using cooperative spectrum sensing is required to analyze with respect to errors present in detection due to fixed threshold. The spectrum allocation on the basis of demand may involve the priority based requests for spectrum allocation. This paper contributes in terms of efficient energy sensing using dynamic threshold strategy. The principle of sensing is optimized using energy sensing using effects of Marcum q function for the PU presence sensing. The effective detection analysis is performed along with energy consumption which shows effective efficiency during sensing work.
