In this study, we address the spectrum handover mechanism for proactive-decision in cognitive radio networks. Spectrum handover occurs when the primary users suddenly appear and the secondary users are using the particular primary user’s licensed channel. The proactive-sensing spectrum handover which the target channel is pre-determined. And handover avoid the sensing time, but the pre-determined target channel may not be available. So we develop a spectrum handover mechanism by using an efficient channel-scheduling algorithm to reduce disabled channel. Its basic idea is in that a new packet is scheduled by migrating some packets to other channels if none of any idle channels can accommodate it; otherwise repeating the other migrate or stay channel processes.
