Underwater Wireless Communication System with the Internet of Underwater Things

The widespread adoption of underwater wireless communications (UWC) has become an important research area to address a variety of military and commercial applications, and there is growing interest in investigating underwater environments in numerous applications. With the advancement of UWC, the underwater Internet of Things (IoUT) has emerged, and various practical applications are expected, and it is recognized as one of the promising technologies. Acoustic, optical, and radio RF carriers used for data transmission in underwater communication failed to provide expected results, so in this paper, we provided a comparative study of existing UWC techniques, their advantages as compared to existing techniques, and optimized methods for transmission and modulation, and it has been identified that the potential IoUT applications by overcoming the challenges possessed by the existing system. We analyzed how IoUT overcomes the challenges faced by traditional techniques of transmission and modulation without compromising the security measures and leads to more efficient communication with less power consumption and transmission loss.
