过去二十年来，传感和通信技术已成功应用于各种事件监测应用，特别是在无法进行长期手动监测的地方。然而，该技术的主要适用性大多局限于陆地环境。另一方面，水下无线传感器网络（UWSN）为水下物种和动物群的远程监测以及与水下航行器、潜艇等的通信开辟了新的空间。然而，与地面无线电通信不同，水下环境由于水介质的高电导率导致大量信号吸收，给可靠通信带来了新的挑战。在本文中，我们提供了不同水下通信技术（即声学、磁学和可见光）的详细技术概述，以及它们在海底环境中的潜力和挑战。还使用真实的实验结果对这些技术及其优缺点进行了详细比较。
Sensing and communication technology has been used successfully in various event monitoring applications over the last two decades, especially in places where long-term manual monitoring is infeasible. However, the major applicability of this technology was mostly limited to terrestrial environments. On the other hand, underwater wireless sensor networks (UWSNs) opens a new space for the remote monitoring of underwater species and faunas, along with communicating with underwater vehicles, submarines, and so on. However, as opposed to terrestrial radio communication, underwater environment brings new challenges for reliable communication due to the high conductivity of the aqueous medium which leads to major signal absorption. In this paper, we provide a detailed technical overview of different underwater communication technologies, namely acoustic, magnetic, and visual light, along with their potentials and challenges in submarine environments. Detailed comparison among these technologies have also been laid out along with their pros and cons using real experimental results.
