Assignee: NATIONAL UNIVERSITY OF DEFENSE TECHNOLOGY
Field: Digital communication (Electrical engineering)
Classification: CPC H  G  Y | IPC G  H

Claim 0:
1. A method for communication, applied to a source node, wherein the method comprises:
determining a first target frequency based on historical sensed information of a destination node, and transmitting a request-to-send (RTS) frame to the destination node at the first target frequency, wherein the destination node obtains first sensed information of the source node based on the RTS frame, and determines a first optimal receiving frequency of the source node based on the first sensed information;
receiving a clear-to-send (CTS) frame transmitted by the destination node at the first optimal receiving frequency, obtaining second sensed information of the destination node based on the CTS frame, and determining a second optimal receiving frequency of the destination node based on the second sensed information; and
transmitting a data frame to the destination node at the second optimal receiving frequency, and receiving an acknowledge (ACK) frame transmitted by the destination node at the first optimal receiving frequency,
wherein the determining a first target frequency based on historical sensed information of a destination node comprises:
determining whether the historical sensed information of the destination node exists;
determining the first target frequency based on the historical sensed information of the destination node, in a case that the historical sensed information of the destination node exists; and
determining the first target frequency based on sensed information of a neighboring node within a single-hop network, in a case that the historical sensed information of the destination node does not exist.
