Published in Institute of Electrical and Electronics Engineers Inc.
In this paper, energy harvesting cooperative cognitive radio (CR) network is studied under a collision constraint of PU. Optimal numbers of CRs cooperate in transmission of primary user (PU), if it remains present in the given channel; otherwise all the CRs transmit their own data in time division scheme. The harvested energy at CR is divided into two parts, one part is allocated for cooperation in PU transmission and the other part is used for its own transmission. The allocation of energy is based on the targeted CR throughput. Influence of an energy allocation parameter and sensing time on throughput performance is studied under the random behaviour of PU. © 2020 URSI.
