ABSTRACT
This chapter proposes an efficient method to improve energy consumption in cognitive radio (CR) networks. In simulation, results are presented in forms of comparisons with the traditional method in two scenarios (cooperative and noncooperative) and with cooperative coarse sensing scheme for cognitive radio network (CC4C) and time-saving and energy-efficient one-bit cooperative spectrum sensing (TSEEOB-CSS) methods. The chapter presents the design of some methods proposed by researchers to improve energy savings in CR, for the purpose of comparison with the proposed method. Energy detection is considered as one of the widely used spectrum sensing techniques due to its simplicity, as it does not need any information about the structure of the primary users (PUs) signals. The spectrum sensing process consumes energy in both the sensing and transmission stages. The proposed method achieves energy saving in the sensing stage and improves the detection performance.
