Abstract

Cognitive radio is a promising technology that aims to enhance the utilization of the radio spectrum. This is achieved by providing opportunistic access to the unlicensed users or the secondary users. In this paper, quality of service (QoS) in cognitive radio networks is investigated for a heterogeneous network model. A modified cognitive radio spectrum sharing algorithm based on the Hungarian algorithm is proposed and compared to first come first served (FCFS) scheduling technique. The modified algorithm proposed a cost function based on the required and the available signal to noise ratio (SNR) of the application and channel, respectively. Simulation results reveal the robustness of the proposed algorithm under nonfading, Rayleigh and Nakagami fading channels in terms of achieved SNR, data rate and spectrum utilization compared to FCFS algorithm.
