Rendezvous method of multi-transceiver unlicensed user of cognitive radio network

摘要

The present invention provides a multi-transceiver unlicensed user rendezvous method of a cognitive radio network. An initial stage of setting an initial communication environment, a selection step of a rendezvous method selecting a channel hopping sequence generation method based on the number of transceivers, a single transceiver rendezvous method or a multi-transceiver rendezvous method Generating a channel hopping sequence, generating a channel hopping sequence, and if an unlicensed user operates on the corresponding channel and tries to rendezvous with the destination node and rendezvous, end the rendezvous process and not rendezvous And, rendezvous step to continue the rendezvous process until rendezvous. The present invention effectively solves the rendezvous problem between unlicensed users with different number of transceivers installed in heterogeneous cognitive radio networks, fully exploits the characteristics of multi-transceiver and reduces the time to acquire rendezvous It reduces the network delay and increases the probability of rendezvous in good quality channels, taking into account the quality of the available channels.
