Jayakrishna P. S., Greshma V., T. Sudha . Energy Efficient Spectrum Sensing Techniques for Cognitive Radio Networks: A Survey. International Journal of Computer Applications. 160, 4 ( Feb 2017), 20-23. DOI=10.5120/ijca2017913033
Cognitive radio has emerged as a tempting solution for the spectrum scarcity problem. This article focuses on the recent trends in energy efficient spectrum sensing techniques for the Cognitive Radio (CR) technology. The increasing demand of cognitive radio and its application increases the urge to make the emerging technologies as energy efficient as possible. Spectrum sensing which is one of the most complex and power intensive tasks in a cognitive radio system when made energy efficient increases the longevity of the network. This survey focuses on the new and efficient energy aware sensing techniques for cognitive radio networks and compares them.
