The Internet of Underwater Things technology can be established using various underwater wireless communications technologies, including acoustic, radio frequency (RF), magnetic induction, and optical. Each of these technologies has its pros and cons; for example, acoustic technology reaches longer distances but is bandwidth limited, while underwater optical wireless communications (UOWCs) can support higher data rates at the cost of short ranges. Besides establishing communication links using these technologies, geographic data tagging of the underwater IoT nodes is also crucial and challenging for several applications. Hence, this talk will provide an overview of the rapidly evolving positioning systems and algorithms for different underwater technologies for location estimation of the underwater IoT nodes and their applications.
