Poster: Overcoming Throughput Degradation in Multi-Radio Cognitive Radio Networks

Dynamic spectrum access through Cognitive Radio Networks (CRNs) and exploiting multiple radios on a single node are two different well accepted techniques for enhancing network performance. Simultaneous usage of both the techniques, i.e., augmenting dynamic spectrum access with multiple radios can improve delay, however, makes throughput worse. Therefore, in this paper, we propose a novel approach to improve network throughput for multi-radio cognitive radio networks. Through ns-3 simulation, we show that our approach can boost throughput without degrading the delay.
