“…The technology works by loading information into sound waves at the transmitting end and transmitting the information to the receiving end via sound waves [3]. In underwater environments, airgun sound sources have been applied as very low-frequency explosive sound sources for realizing long-distance information transmission [4].With the continuous progress of underwater acoustic communication technology, the demand for a higher speed rate of hydroacoustic communication is also increasing. In practical applications, the closerange high-rate hydroacoustic communication technology has been quite mature.…”

To meet the requirement of a higher speed rate for hydroacoustic communication, an innovative scheme is proposed to simulate an airgun sound source by superimposing two different frequency Ricker Wavelets to form a multi-wave Ricker Wavelet. On the receiver side, two bandpass filters are employed to recover the original information. First, the characteristics of a single Ricker Wavelet, a multi-wave Ricker Wavelet, and an airgun sound source were compared. We found that the multi-wave Ricker Wavelet has characteristics that are similar to the airgun sound source, which leads to the conclusion that using a multi-wave Ricker Wavelet is the best way to simulate the airgun sound source. Secondly, we proposed a method to simulate the airgun sound source for transmission by superposition of two multi-wave Ricker Wavelets of different frequencies, which was an innovative scheme capable of sending two bits of information in one code element duration, thus better meeting the demand for higher communication rates in hydroacoustic communication. Finally, we conducted simulation experiments to verify the validity of the above conclusions. The analysis and elaboration can provide a novel and efficient solution for the field of hydroacoustic communication.

The underwater wireless sensor networks (UWSNs) area is a developing area of research since there are tremendous opportunities like surveying marine life, installing and monitoring optical cables, detecting earthquakes, and surveillance of territorial borders. Though many applications exist, underwater research explored to date is less than five percent as it poses many issues and challenges like water currents, temperature, pressure, water salinity, disturbance by aquatic animals, and many more factors that affect the performance of sensors deployed inside water. A significant issue UWSNs face is focusing on energy efficiency to extend the life of submerged sensors placed in isolated areas. Resolving localization concerns is a primary additional concern. In this comprehensive survey, the basics of UWSNs are covered in the introduction, followed by a thorough literature review of the existing works mainly focusing on localization, energy efficiency, Bio-inspired algorithms (BIA), and the impact of implementing Machine Learning (ML) are discussed. In concurrent sections, we have discussed attributes, parameters useful for analysis, issues and challenges in UWSN, soft computing techniques, software and hardware tools available for extended research, and opportunities in UWSN. The researchers could gain perspective pathways at the end of this survey.
