Collaborative spectrum sensing in cognitive radio networks mitigates the negative propagation effects of the wireless channel and increases the sensing reliability. Collaborative sensing requires sensors to share their local spectrum sensing information (SSI) with other users. This paper proposes distributed iterative time slot allocation algorithms for SSI sharing on a dedicated common control channel...
In this paper a distributed multiagent, multiband reinforcement learning based sensing policy for cognitive radio ad hoc networks is proposed. The proposed sensing policy employs secondary user (SU) collaboration through local interactions. The goal is to maximize the amount of available spectrum found for secondary use given a desired diversity order, i.e. a desired number of SUs sensing simultaneously...
