A media access control method for an underwater acoustic network based on reorganized time slot directional reception. When multiple underwater nodes simultaneously send DATA data packets to the sink node, it is determined whether the DATA data packet can arrive at the time slot start point of the reorganized time slot of the sink node. If so, it is sent; otherwise, it is sent after a backoff period. After the DATA data packet arrives at the sink node, the sink node determines the position of the sending node based on the DATA data packet and receives the DATA information packet in the DATA data packet through the directional reception method. A media access control method for an underwater acoustic network based on reorganized time slot directional reception can effectively improve the transmission throughput. After a successful channel reservation, the receiving node performs backoff and actively waits for all underwater nodes that need to send to finish sending the DATA data packet, which can effectively reduce the collision of DATA data packets at the sink node. Using the directional reception technology, it is applicable to large-scale data collection-type underwater acoustic sensor networks.
