Abstract
This paper deals with the cognitive radio network (CRN) in which cooperative spectrum sensing technique is used between cooperative nodes (CNs). Additionally, power ratio and secondary user (SU) average throughput expressions were taken into account to obtain the idea about quality of service (QoS) improvement at the SU. However, total transmitted power (pt) and interference power are taken as constraints to find the relationship between normalized effective capacity and QoS exponent θ. Moreover, power ratio and SU average throughput are calculated in the presence of mean channel gains. Simulation results show that in direct transmission, smaller the value of θ, larger is the effective capacity between secondary source (SS) and secondary destination (SD).
