水下物联网(IoT)是一种新型的物联网，被定义为智能互联的水下物体网络。Iout有望实现各种实际应用，如环境监测、水下勘探和灾害预防。通过这些应用，Iout被认为是发展智能城市的潜在技术之一。为了支持IOUT的概念，水下无线传感器网络(UWSNs)已经成为一种很有前途的网络系统。UWSNs不同于传统的地域无线传感器网络，具有传播时延长、带宽窄、可靠性低等特点。这些独特的特性将是Iout面临的巨大挑战。在本文中，我们对Iout进行了全面的研究，本文的主要贡献有三个方面：(1)介绍和分类了能够突出Iout重要性的实际水下应用；(2)指出了UWSNs与传统TWSNs的区别，这些不同是Iout面临的主要挑战；(3)对Iout上设计可靠通信协议的技术核心--信道模型进行了研究和评估。
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.
