  • 摘要: 水下滑翔機的運動導致滑翔機位置和相對距離的變化，引起了滑翔機間的信號傳輸時間改變，進而導致水下滑翔機間通信可靠性的下降。傳統(tǒng)水下媒體接入控制(MAC)協(xié)議面向靜態(tài)拓撲網(wǎng)絡，不適用于動態(tài)變化的網(wǎng)絡拓撲。該文提出一種水下滑翔機組網(wǎng)的動態(tài)MAC機制。新機制利用水下滑翔機運動模型進行位置預測，根據(jù)預測結(jié)果和相鄰滑翔機間的位置共享動態(tài)計算時隙長度，并進行分配和預約收發(fā)，水下滑翔機在收發(fā)過程中以團隊協(xié)作方式避免沖突。實驗結(jié)果表明，該機制的數(shù)據(jù)包投遞率與運動預測MAC(P-MAC)和預約MAC(R-MAC)協(xié)議相比分別提高了12%和25%，更適用于由水下滑翔機組成的動態(tài)網(wǎng)絡。
    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.
