A Fair Data Transmission Strategy in Underwater Acoustic Sensor Networks
When Underwater Acoustic Sensor Networks (UASNs) transmit large amounts of data, the collisions of link layer increase, and it causes that the traffic load of link is heavier. These situations could easily lead to network data loss, unfair channel competition and unfair data transmis - sion. In order to reduce collisions and improve the reliability and fairness of data transmission, Time Distance Ratio (TDR) and underwater fairness transmission are presented, and this paper proposes a Fair Data Transmission Strategy (FDTS) for UASNs, which consists of queue management, transmission control and competition waiting. It focuses on considering the fairness of data transmission and enhancing network performance in case of network congestion. Simulation results show that when network load is heavier, FDTS not only effectively improve the fairness of data transmission and the success rate of delivery but also reduce end-to-end delay, average energy consumption and TDR of packets
