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

Claim 6:
7. An electronic device, comprising:
a memory storing a computer program; and
a processor, wherein
the electronic device, when executes the computer program on the processor, is configured to:
determine a first target frequency based on historical sensed information of a destination node, and transmit 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;
receive a clear-to-send (CTS) frame transmitted by the destination node at the first optimal receiving frequency;
obtain second sensed information of the destination node based on the CTS frame, and determine a second optimal receiving frequency of the destination node based on the second sensed information;
transmit a data frame to the destination node at the second optimal receiving frequency; and
receive an acknowledge (ACK) frame transmitted by the destination node at the first optimal receiving frequency,
wherein the electronic device is further configured to:
determine whether the historical sensed information of the destination node exists;
determine 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
determine 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.
