Underwater acoustic communication method, device, equipment and storage medium

The invention discloses an underwater acoustic communication method, device and equipment and a storage medium, and relates to the technical field of communication, and the method comprises the steps: obtaining a transmission request message broadcasted by a sending node through a control channel; performing quality estimation on the available data channel based on the transmission request message, screening a target data channel based on a quality estimation result to determine a data transmission scheme containing a target data channel sequence number, and then executing a backoff operation based on a local to-be-processed data queue length; if the backoff operation is successfully executed, a reply message containing a data transmission scheme is sent to the sending node through the control channel; and if the reply message is the reply message which is received by the sending node for the first time and corresponds to the transmission request message, obtaining a to-be-relayed data packet sent by the send
