Rendezvous Method of Unauthorized Users with Multiple Transceivers in a Cognitive Wireless Network

摘要

The present invention provides a rendezvous method for a non-authorized user equipped with multiple transceivers in a cognitive radio network including four stages. In this method, an early stage is to set up an early communication environment, and a rendezvous selection step is to select a channel hopping order generation method according to the number of transceivers and to generate a channel hopping order: a single transceiver or multiple transceiver rendezvous methods And a rendezvous step: the unauthorized user is operating on the corresponding channel and attempts to rendezvous with his destination load. When you rendezvous, you can include the step of ending this rendezvous process, or repeating this process until it is loaded and rendezvous. The present invention solves the problem of rendezvous when unauthorized users are equipped with different number of transceivers in a heterogeneous wireless network and fully utilizes the characteristics of the transceiver to reduce rendezvous time while reducing network delay. In addition, the quality of available channels is taken into account and the possibility of rendezvous in high-quality channels increases.
