Abstract
In cognitive radio (CR) networks, in hybrid mode of operation, unlicensed secondary users (SUs) are allowed to transmit data over the busy frequency band and idle frequency band hence the throughput performance compared to underlay mode and overlay mode is improved. In this paper, we study a novel queueing analytical framework to measure the performance of the hybrid CR. A continuous time Markov chain model is presented to capture the activity of licensed primary users and unlicensed SUs in underlay and overlay mode. The queueing based performance of the proposed model is measured using the matrix geometric method. The ranges of various performance parameters are also determined.
