Abstract

In cognitive radio networks (CRNs), in the case that primary users (PUs) reclaim their channels, the secondary users occupying the spectrum of PUs may have to stop their transmission, waiting at current channel or perform spectrum handoff, i.e., switch to other channels. For handoff SUs, designing target spectrum selection schemes is of particular importance for it may affect the transmission performance and user quality of service (QoS) significantly. In this paper, we study spectrum handoff scheme design for a CRN deployed multiple channels. Jointly taking into account the characteristics of handoff candidate channels and user QoS requirements, we propose a channel characteristics and user QoS aware handoff target spectrum selection scheme for handoff SUs. Simulation results demonstrate the effectiveness of the proposed scheme.
