A Survey on Underwater Wireless Power and Data Transfer System

Abstract

This research extensively explores contemporary techniques in Underwater Wireless Power and Data Transfer (WPDT), as found in recent literature over the past 5 years. These techniques involve Magnetic Induction (MI), acoustic communication, and optical communication. The study aims to evaluate transmission efficiency, propose solutions to overcome range limitations, facilitate integration, and precisely map multilayer networks. The research methodology includes proposed solutions to address the limitations of each transmission technique, multilayer network mapping, and model validation. Evaluation is conducted on the relative efficiency of each method, including power loss at each layer, the connection matrix between layers, and transmission speed. Simulations reveal power loss at nodes in each layer and the connection matrix between layers. The power loss at each node shows random values, providing a realistic aspect close to real-world scenarios, offering in-depth insights into the characteristics and performance of multilayer networks in an underwater context. The research series, involving literature elaboration, technological approaches, illustrations, and simulations, demonstrates the effectiveness of the proposed model. Simulation results indicate the potential of this model in real-world scenarios, with tolerable power loss values, suggesting that multilayer networks could be a solution to classic challenges in underwater power and data transmission. The hope of this preliminary study is to provide new insights and make a significant contribution to understanding and designing reliable underwater power and data transfer systems in the future.

Evaluation Method for Underwater Ultrasonic Energy Radiation Performance Based on the Spatial Distribution Characteristics of Acoustic Power

“…Moreover, the acoustic energy radiation process occupies an important position in the underwater ultrasonic wireless energy transmission process, which directly affects the energy transmission efficiency and the overall system performance [ 20 ]. Therefore, acoustic radiation efficiency is particularly critical in underwater ultrasonic wireless energy transfer technology, and its improvement is one of the key development directions for the latter [ 21 ]. Existing evaluation methods focusing on acoustic field analysis usually concentrate on a single parameter, ignoring the dynamic distribution of acoustic energy in complex water [ 22 ].…”
