Abstract
The Internet of Underwater Things (IoUT) is a novel class of Internet of Things (IoT), and is defined as the network of smart interconnected underwater objects. IoUT is expected to enable various practical applications, such as environmental monitoring, underwater exploration, and disaster prevention. With these applications, IoUT is regarded as one of the potential technologies toward developing smart cities. To support the concept of IoUT, Underwater Wireless Sensor Networks (UWSNs) have emerged as a promising network system. UWSNs are different from the traditional Territorial Wireless Sensor Networks (TWSNs), and have several unique properties, such as long propagation delay, narrow bandwidth, and low reliability. These unique properties would be great challenges for IoUT. In this paper, we provide a comprehensive study of IoUT, and the main contributions of this paper are threefold: (1) we introduce and classify the practical underwater applications that can highlight the importance of IoUT; (2) we point out the differences between UWSNs and traditional TWSNs, and these differences are the main challenges for IoUT; and (3) we investigate and evaluate the channel models, which are the technical core for designing reliable communication protocols on IoUT.

Summary
There has been a growing trend toward smart cities. One of the most important techniques to be used is the Internet of Things (IoT), which is defined as “the infrastructure of the information society” [1]. In UWSNs, the sensors are the nodes with acoustic modems, and are distributed in either shallow or deep water. The unique properties of UWSN, such as long propagation delay, narrow bandwidth, and low reliability, would be great challenges for IoUT. To investigate the reliability of IoUT, the channel models play a vital role. This paper provides a comprehensive study of the IoUT applications, challenges, and channel models. This paper provides studyapplications; of the IoUT applications, challenges, and channel we introduce and classifya comprehensive the potential IoUT models. The main contributions of this paper are threefold: we point out the challenges for IoUT (i.e., the differences between UWSNs and TWSNs); and. UWSN channel models, which are the technical core for IoUT.
