The increasing need for observation in seawater or ocean monitoring systems has ignited a considerable amount of interest and the necessity for enabling advancements in technology for underwater wireless tracking and underwater sensor networks for wireless communication. This type of communication can also play an important role in investigating ecological changes in the sea or ocean-like climate change, monitoring of biogeochemical, biological, and evolutionary changes. This can help in controlling and maintaining the production facilities of outer underwater grid blasting by deploying unmanned underwater vehicles (UUVs). Underwater tracking-based wireless networks can also help in maintaining communication between ships and divers, submarines, and between multiple divers. At present, the underwater acoustic communication system is unable to provide the data rate required to monitor and investigate the aquatic environment for various industrial applications like oil facilities or underwater grit blasting. To meet this challenge, an optical and magnetic tracking-based wireless communication system has been proposed as an effective alternative. Either optical or magnetic tracking-based wireless communication can be opted for according to the requirement of the potential application in sea or ocean. However, the hybrid version of optical and wireless tracking-based wireless communication can also be deployed to reduce the latency and improve the data rate for effective communication. It is concluded from the discussion that high data rate optical, magnetic or hybrid mode of wireless communication can be a feasible solution in applications like UUV-to-UUV and networks of aquatic sensors. The range of the proposed wireless communication can be extended using the concept of multihop.
随着对海水或海洋监测系统中观测需求的不断增加，人们对水下无线跟踪和水下传感器网络等无线通信技术的进步产生了浓厚的兴趣和需求。这种通信方式在调查海洋生态变化或气候变化、监测生物地球化学、生物和进化变化方面也能发挥重要作用。它有助于通过部署无人水下航行器（UUV）来控制和维护外海水下网格爆破的生产设施。基于水下跟踪的无线网络还可以帮助船只、潜水员、潜艇和多个潜水员之间保持通信。目前，水下声通信系统无法为各种工业应用（如石油设施或水下喷砂）提供监测和调查水生环境所需的数据速率。为了应对这一挑战，已经提出了一种基于光学和磁跟踪的无线通信系统作为一种有效替代方案。根据在海洋中的潜在应用需求，可以选择基于光学或磁跟踪的无线通信。然而，也可以部署光和无线跟踪混合版本的无线通信，以减少延迟并提高有效通信的数据速率。讨论得出的结论是，在 UUV 到 UUV 和水下传感器网络等应用中，高速率的光学、磁或混合模式的无线通信是一种可行的解决方案。可以使用多跳的概念来扩展所提出的无线通信的范围。
