In cognitive radio networks (CRNs), secondary users (SUs) can flexibly access primary users' (PUs') idle spectrum bands, but such spectrum opportunities are dynamic due to PUs' uncertain activity patterns. In a multihop CRN consisting of SUs as relays, ...
Cognitive radio (CR) technology opens the licensed spectrum bands for opportunistic usage and initiates spectrum trading to improve the spectrum utilization. In this paper, we investigate the path selection problem in multihop cognitive radio networks (...
Dual band capable cognitive radio networks (CRNs) have the advantage of being able to fall back to the secondary frequency band when the primary user (PU) is active. We analyze the connectivity of dual band capable CRNs and show the effect of primary ...
