Abstract
The present invention relates to a Torus-Quorum based channel rendezvous method for directional antennas. A pair of directional antennas facing any side initially points to the other party mutually in one Torus-Quorum system cycle through a rotation closure attribute of a Torus-Quorum system; and a receiver and a sender switch to a same available channel according to frequency hopping sequences to realize channel rendezvous. In the Torus-Quorum based channel rendezvous method for directional antennas proposed in the present invention, the directional antennas are rotated based on the Torus-Quorum, and elements are ensured to coincide with each other within limited time through the rotation closure attribute of the Torus-Quorum system, i.e., directions are opposite, thereby effectively shortening channel rendezvous time of the directional antennas.
