Abstract：The movement of the underwater gliders leads to the change in the position and relative distance among the gliders, which causes a change in the propagation delay of packets between gliders, and then it leads to a decrease in the reliability of communication between underwater gliders. The traditional underwater Media Access Control (MAC) protocols are for static topology networks and do not apply to dynamically varying network topology. Thus, a new MAC mechanism for the underwater glider networks is proposed. It predicts location based on underwater glider motion model. It calculates time slots dynamically according to the predicted results and the shared position information of underwater gliders. Then, it allocates time slots and reserves to the send and the receive. Underwater gliders avoid collisions with teamwork in the process of sending and receiving. Simulation results show that in this mechanism, the packet received rate increases by 12% and 25% comparing to the Prediction based MAC (P-MAC) protocol and Reservation based MAC (R-MAC) protocol, respectively. The result indicates that the new mechanism is more suitable for the dynamic network composed of underwater gliders.
