Energy efficiency in future wireless networks: Cognitive radio standardization requirements

Energy consumption of mobile and wireless networks and devices is significant, indirectly increasing greenhouse gas emissions and energy costs for operators. Cognitive radio (CR) solutions can save energy for such networks and devices; moreover, the energy consumption of CR technologies themselves have to be considered. This paper discusses ways in which standardization efforts can assist the use of CR to both save energy for mobile/wireless communications, and ensure that the energy consumption in CR networks and devices is minimized. Compelling argument for such solutions are presented.
