In cognitive radio (CR) networks, unlicensed users (or secondary users, SUs) can explore and exploit white spaces, which are the underutilized licensed channels, conditional on acceptable interference to the licensed users (or primary users, PUs). This paper investigates the effects of network characteristics on the network performance of a routing scheme called Cognitive Radio Q-routing (CRQ-routing),...
Cognitive radio (CR) has been proposed to enable unlicensed users (or secondary users, SUs) to exploit the underutilized licensed channels (or white spaces) owned by the licensed users (or primary users, PUs). This article presents a simple and pragmatic reinforcement learning (RL)-based routing scheme called Cognitive Radio Q-routing (CRQ-routing). CRQ-routing is a spectrum-aware scheme that finds...
