Available in PDF, EPUB and Kindle. Book excerpt: Autonomous underwater vehicles (AUVs) are emerging as a promising solution to help us explore and understand the ocean. The global market for AUVs is predicted to grow from 638 million dollars in 2020 to 1,638 million dollars by 2025 – a compound annual growth rate of 20.8 percent. To make AUVs suitable for a wider range of application-specific missions, it is necessary to deploy multiple AUVs to cooperatively perform the localization, tracking and formation tasks. However, weak underwater acoustic communication and the model uncertainty of AUVs make achieving this challenging. This book presents cutting-edge results regarding localization, tracking and formation for AUVs, highlighting the latest research on commonly encountered AUV systems. It also showcases several joint localization and tracking solutions for AUVs. Lastly, it discusses future research directions and provides guidance on the design of future localization, tracking and formation schemes for AUVs. Representing a substantial contribution to nonlinear system theory, robotic control theory, and underwater acoustic communication system, this book will appeal to university researchers, scientists, engineers, and graduate students in control theory and control engineering who wish to learn about the core principles, methods, algorithms, and applications of AUVs. Moreover, the practical localization, tracking and formation schemes presented provide guidance on exploring the ocean. The book is intended for those with an understanding of nonlinear system theory, robotic control theory, and underwater acoustic communication systems.
Download or read book Underwater Information Perception and Processing Via Underwater Sensor Networks written by Meiqin Liu and published by Springer. This book was released on 2024-12-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the latest advances and trends in information perception and processing of underwater sensor networks (USNs). Underwater sensor networks are networks of autonomous sensor nodes distributed over a given region of water to collaboratively perform a given task. Nearly 70% of the Earth's surface is covered by water, mainly oceans, and more than 80% of the ocean remains unexplored. The emergence of USNs is a new direction in ocean exploration and data collection. USNs offer many applications in both civilian and non-civilian fields. However, due to the characteristics of underwater environments, USNs face challenges such as limited bandwidth, high propagation delay, media access control, routing, resource utilization, power limitation, etc. Researchers have studied and provided many techniques over the past decades to address these issues. This book systematically summarizes the development and covers a wide range of applications of USNs, including mobile node localization, target detection, target recognition, target tracking, sensor scheduling, and environmental monitoring. It also focuses on the introduction of new technologies, including deep reinforcement learning, into underwater information perception and processing. This book is suitable for university lecturers, graduate students, and industry professionals working in the field of USNs.
Download or read book A MAC Protocol for Ad hoc Underwater Acoustic Sensor Networks written by Borja Peleato and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A medium access control (MAC) protocol is proposed that is suitable for non-synchronized ad-hoc networks, and in particular for the energy-constrained underwater acoustic networks which are characterized by long propagation delays. The protocol exploits the difference in the link lengths between the nodes instead of waiting times proportional to the maximal link length. To do so, it relies on a receiver's ability to tolerate a certain level of interference. By minimizing the length of the hand-shake procedure preceeding the data transmission, the throughput efficiency is increased as compared to the previously proposed protocols, while collision avoidance minimizes the energy consumption.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the latest research on cognitive network-layer methods and smart adaptive physical-layer methods in underwater networks. Underwater communication requires extendable and delay-tolerant underwater acoustic networks capable of supporting multiple frequency bands, data rates and transmission ranges. The book also discusses a suitable foreground communication stack for mixed mobile/static networks, a technology that requires adaptive physical layer waveforms and cognitive network strategies with underlying cooperative and non-cooperative robust processes. The goal is to arrive at a universally applicable standard in the area of Underwater Internet-of-Things [ISO/IEC 30140, 30142, 30143]. The book is the second spin-off of the research project RACUN, after the first RACUN-book "Underwater Acoustic Networking Techniques" (https://link.springer.com/book/10.1007%2F978-3-642-25224-2)

Download or read book Analyzing the Performance of Multi hop Underwater Acoustic Sensor Networks written by and published by . This book was released on 2007 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-hop underwater acoustic sensor networks constrain the performance of medium access control protocols. The efficiency of the well-known RTS-CTS scheme is degraded due to long propagation delays of such networks. Recently, interest in Aloha variants has surfaced; however, the performance of such protocols within the context of multi-hop networks is not well studied. In this paper, we identify the challenges of modeling contention-based medium access control protocols and present a model for analyzing Aloha variants for a simple string topology as a first step toward analyzing the performance of contention-based proposals in multi-hop underwater acoustic sensor networks. An application of the model suggests that Aloha variants are vary sensitive to traffic loads and network size.

Available in PDF, EPUB and Kindle. Book excerpt: Underwater acoustic communication technologies are becoming increasingly important due to the widespread adoption of autonomous unmanned vehicles (AUVs) in ocean data collection. The communication support provided by acoustic telemetry makes it possible for multiple AUVs to coordinate during underwater missions. Mobile underwater acoustic communications is still an active field of research. Various technical issues, such as reliable communications between two mobile nodes, multi-user communications, and joint optimization of navigation and communications are awaiting for satisfactory solutions. In this thesis, we develop solutions for several of these issues. The first effort considers an adaptive communication system based on time-reversed orthogonal frequency-division multiplexing methods for the underwater acoustic channels. In this adaptive system, the receiver sends truncated q-functions to the transmitter, which then performs mapping selection for the individual sub-carriers. Simulations demonstrate the advantages of the proposed adaptive system, achieving higher data rates and lower feedback costs. The second effort addresses the extended propagation delay in closed-loop adaptive communications for mobile platforms. An adaptive modulation strategy is developed based on reinforcement learning. Specifically, a Dyna-Q algorithm is presented to improve the communication throughput. Our simulations show that the Dyna-Q algorithm achieves a higher throughput and lower bit-error-rates than the direct feedback. The third effort provides a solution to the acoustic communication problem with multiple AUVs. We propose a virtual multiple-input/multiple-output (MIMO) strategy that selects transmitters from a subset of AUVs to form a virtual transmit array. A user selection algorithm is used to determine the active AUV subset for data transmissions. Adaptive modulation is combined to further improve throughput. The user selection and modulation choice are determined by the predicted data rates, thus increasing spectral efficiency of the uplink. In the last effort of this thesis, we address the trajectory optimization for underwater data muling with mobile nodes. In this scenario, multiple AUVs sample a mission area and autonomous surface vehicles (ASVs) visit underway AUVs to retrieve survey data. We propose a nearest-K reinforcement learning algorithm to optimize ASV travel tracks. The learning-based algorithm can simultaneously maximize fairness in data transmissions and minimize the travel distance of the surface nodes.
