By using the present invention, the problem of rendezvous of unlicensed users equipped with different quantities of transceivers in heterogeneous cognitive radio networks is effectively resolved. Moreover, the characteristic of multiple transceivers is fully utilized, and the time-to-rendezvous is reduced, so that the network delay is reduced. In addition, the quality of available channels is considered, and the probability of rendezvous on a channel with desirable quality is increased.
