摘要

水下聲波感測網路與陸上無線感測網路特性截然不同，水下聲波感測網路利用聲波進行傳輸，造成水下網路擁有高傳播延遲的特性，若將陸上路由機制直接套用於水下網路，將會衍生出許多問題。因此本論文設計出適用於水下網路環境之路由協定，且在水下聲波感測網路中提出協同合作傳輸，進而減少在水下聲波感測網路中傳送封包之端點到端點間的延遲。最後本篇論文提出座標定位及收集鄰居資訊之協同合作傳輸協定，名為水下聲波網路中避免能量空洞之非同步協同合作傳輸協定。透過實驗模擬，發現本篇論文所提出之傳輸協定，在點對點的延遲、網路傳輸效能以及電量消耗的表現上有顯著的改善。

Underwater acoustic sensor network uses sound waves to be transmitted, resulting in underwater network with high propagation delay characteristics. Therefore, this paper designed for underwater network environment routing protocols, thereby reducing the underwater acoustic sensor network to send packets to the end-to-end delay and for collaborative work on underwater acoustic transmission sensor network. Through simulation, this paper found that the proposed routing protocol SCTP, the delay in the point to point, network transmission performance and power consumption of a significant improvement in performance.
