Abstract
In the cognitive wireless networks, the channel handoff strategy which controls the communication in a channel to migrate to another channel when primary users hope to access directly affects the quality-of-service of cognitive users and primary users. In this paper, we propose a Cognitive Global Control Plane (CGCP) which embraces the controlling of spectrum sensing, channel handoff and node mobility. With the CGCP architecture, an adaptive channel handoff strategy is given out. We analyze the handoff algorithm with Markov chain theory and some tradeoffs between performance and overhead. The results of performance evaluation show that the channel handoff strategy can adaptively and flexibly perform channel handoff.
