Abstract
In this paper, the performance of throughput analysis is done in an energy efficient amplify and forward (AF) relay assisted cognitive radio network. An effective optimization problem is formulated to observe the effect of two relays in proposed scenario. To achieve the desired goal, a constrained optimization problem is studied under the constraints of probability of detection threshold and maximum limitation of fixed power budget. On the basis of mathematical formulation and effective searching technique, an optimal sensing time is found to achieve high throughput of the proposed system.
