摘要：
In this paper, energy efficiency for cooperative spectrum sensing in cognitive radio network is investigated and optimized. The novel mathematical formulation of energy efficiency maximization problem by considering number of secondary users, sensing time, and transmission time as design parameters with protection of primary user from SU transmission has been done. In order to solve the formulated problem, first the optimal expression for number of secondary users is formulated, then, an iterative sub optimal algorithm is proposed to obtain optimal sensing and transmission time. Numerical results and illustrative plots demonstrate the correctness and optimality of the proposed algorithm and show the improved performance over the state of arts. (C) 2018 Elsevier GmbH.
