Abstract:  In order to improve the reliability of underwater data transmission, this paper presents a cooperative data transmission algorithm based on random linear network coding. First, the algorithm find the data forwarding link for the source node and let the data be forwarded through multiple links. Second, the network coding method is used to encode the data packets to avoid repeated data transmission. Finally, the packet transmission time slot of each node is scheduled to avoid signal conflicts between nodes. The simulation result shows that this algorithm not only improves the network channel utilization and the data transmission reliability, but also has a good stability.
