The work, titled "3H-UWAC (three-hop underwater wireless acoustic communication) based on SOFAR Plane: A Novel Relay Deployment Technique" August 2022 Coverage enhancement of underwater IoT using multilevel acoustic communication networks 1 min read · Wed, Aug 31 2022 News IoT Underwater acoustic communication networks (UACNs) are considered a key enabler to the underwater internet of things (UIoT). UACN is regarded as essential for various marine applications such as monitoring, exploration, and trading. However, a large part of existing literature disregards the 3-dimensional (3D) nature of the underwater communication system. In this paper, we propose a K-tier UACN that acts as a gateway that connects the UIoT with the Space-Air-GroundSea Integrated System (SAGSIS). The proposed network architecture consists of several tiers along the vertical direction with Authored News November 2024 KAUST-CTL researchers awarded IEEE Honorary Mention in 2024 Communication Society Student Competition 1 min read · Sat, Nov 9 2024 Two innovative projects from King Abdullah University of Science and Technology (KAUST), led by PhD candidate Yingquan Li and his collaborators, have received Honorary Mentions in the IEEE Communications Society (ComSoc) Student Competition. The projects, aimed at enhancing disaster rescue operations and improving communication for Red Sea fishermen, were selected among the top 16 out of 93 international submissions. This achievement underscores KAUST’s commitment to advancing research that addresses societal needs through technology. Project 1: Development of a GPS-independent Localization
