Title:
UNDERWATER ACOUSTIC NETWORK TIME SLOT MAC PROTOCOL METHOD, SYSTEM, AND DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/267107
Kind Code:
A1
Abstract:
Disclosed in the present invention are an underwater acoustic network time slot medium access control (MAC) protocol method, system, and device, and a medium. The method comprises the following steps: dividing a sending channel into a superframe structure containing M time slots, and performing initialization setting on the weight of each time slot of each node; updating a sending probability of each time slot according to the weight of each time slot, and obtaining the time slot for data packet transmission according to the sending probability; updating a time slot revenue according to a receiving condition of an acknowledgement (ACK) packet, and updating the weight of each time slot according to the time slot revenue; obtaining a cycle period according to a superframe length, and updating a time slot probability of each node according to the cycle period until the time slot probability distribution of each node converges. According to the present invention, the evolutionary game theory is simulated, a distributed underwater acoustic network MAC protocol which does not need time synchronization and only depends on local information to adaptively form a sending policy of each node can be realized, the conflict probability of data transmission is reduced to a greater extent, such that higher data delivery rate and throughput performance are realized, and the present invention can be widely applied to MAC.
