Optimal Channel Selection Rate of Slave Terminal for Rendezvous Channel Scheme based on Channel Occupancy Rate

In dynamic spectrum access based on cognitive radio, two terminals (master and slave) cannot recognize the accessing channel. For exchanging the control signal in order to recognize the accessing channel, the rendezvous channel scheme based on channel occupancy ratio (COR) is proposed. Master and slave select the channel with minimum COR and thus high speed rendezvous channel is achieved. The channel selection rate of slave to each channel is constant but it should be adaptively changed in accordance with the distribution of COR. This paper construct the optimal channel selection rate of slave based on theoretical analysis. The optimal channel selection rate achieves the minimum required time slots as well as satisfying the required probability of completing exchanging control signals.
