#$%^&*AU2017374058A820190704.pdf#####ABSTRACT The present invention discloses a method for rendezvous of unlicensed users having multiple transceivers in cognitive radio networks, including four stages: an initial stage: setting an initial communication environment; a stage of selecting a rendezvous method: selecting a method for generating a channel hopping sequence according to the quantity of transceivers; a stage of generating a channel hopping sequence: using a single-transceiver rendezvous method or a multiple-transceiver rendezvous method to generate a channel hopping sequence; and a rendezvous stage: running, by an unlicensed user, on a corresponding channel and attempting to rendezvous with a destination node of the unlicensed user, where if rendezvous is achieved, the rendezvous process ends; and if rendezvous is not achieved, the rendezvous process continues until rendezvous is achieved. 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.
