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)

Available in PDF, EPUB and Kindle. Book excerpt: A blend of introductory material and advanced signal processing and communication techniques, of critical importance to underwater system and network development This book, which is the first to describe the processing techniques central to underwater OFDM, is arranged into four distinct sections: First, it describes the characteristics of underwater acoustic channels, and stresses the difference from wireless radio channels. Then it goes over the basics of OFDM and channel coding. The second part starts with an overview of the OFDM receiver, and develops various modules for the receiver design in systems with single or multiple transmitters. This is the main body of the book. Extensive experimental data sets are used to verify the receiver performance. In the third part, the authors discuss applications of the OFDM receiver in i) deep water channels, which may contain very long separated multipath clusters, ii) interference-rich environments, where an unintentional interference such as Sonar will be present, and iii) a network with multiple users where both non-cooperative and cooperative underwater communications are developed. Lastly, it describes the development of a positioning system with OFDM waveforms, and the progress on the OFDM modem development. Closely related industries include the development and manufacturing of autonomous underwater vehicles (AUVs) and scientific sensory equipment. AUVs and sensors in the future could integrate modems, based on the OFDM technology described in this book.

This book was released on 2014 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underwater communication and networks will play a major role in many future commercial, environmental, and military applications, including disaster prevention, tactical surveillance, offshore exploration, pollution monitoring, tsunami detection, sunken airplane or vessel localization and oceanographic data collection. Acoustic wireless communication is the transmission technology of choice for underwater networked systems. However, underwater acoustic signals propagating in water suffer from significant path loss, time-varying multipath propagation, Doppler spread, and high propagation delay. These formidable challenges limit the available bandwidth for underwater acoustic communications, while the rapidly varying channel results in communication links that are highly unreliable, ultimately hindering advancements in underwater networked communications. As a consequence, the field of underwater communication and networking is still in its infancy. The objective of this research work is to further push the boundaries in underwater communication and networking by developing a versatile reconfigurable underwater networking platform, analyzing the statistical channel properties of short-range shallow water communication environments and exploring advanced signal processing techniques to improve the network throughput, provide a secure communication means, and offer a low-cost distributed networked localization and time synchronization framework for underwater acoustic networks. Specifically, in this dissertation, we first present the development of a software-defined underwater networking testbed we developed at the University at Buffalo. In the second part of this work, we investigate underwater acoustic channel characteristics in short-range shallow water environments. In the third part, we propose CDMA-based analog network coding for underwater acoustic sensor networks with the objective to improve the network throughput. In the forth part, we explore CDMA-based analog network coding to provide a secure underwater acoustic communications means. Finally, in the fifth part of this work, we propose a low-cost distributed networked localization and time synchronization framework for underwater acoustic testbeds.

Download or read book Underwater Acoustic Digital Signal Processing and Communication Systems written by Robert Istepanian and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underwater acoustic digital signal processing and communications is an area of applied research that has witnessed major advances over the past decade. Rapid developments in this area were made possible by the use of powerful digital signal processors (DSPs) whose speed, computational power and portability allowed efficient implementation of complex signal processing algorithms and experimental demonstration of their performance in a variety of underwater environments. The early results served as a motivation for the development of new and improved signal processing methods for underwater applications, which today range from classical of autonomous underwater vehicles and sonar signal processing, to remote control underwater wireless communications. This book presents the diverse areas of underwater acoustic signal processing and communication systems through a collection of contributions from prominent researchers in these areas. Their results, both new and those published over the past few years, have been assembled to provide what we hope is a comprehensive overview of the recent developments in the field. The book is intended for a general audience of researchers, engineers and students working in the areas of underwater acoustic signal processing. It requires the reader to have a basic understanding of the digital signal processing concepts. Each topic is treated from a theoretical perspective, followed by practical implementation details. We hope that the book can serve both as a study text and an academic reference.

Download or read book On the Impacts and Benefits of Implementing Full Duplex Communications Links in an Underwater Acoustic Network written by and published by . This book was released on 2002 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic signals offer a means of establishing wireless networks in shallow water regions. These networks may provide command and control for autonomous underwater vehicles, forward reporting by arrays of sensor grids, ad hoc communications links to covert forces, or positive control of unmanned, forward-deployed weapons systems. However, the capacity limitations and extreme propagation delays of acoustic communications must be addressed to ensure timely, predictable message delivery. This paper presents the status of current experimentation at the Naval Postgraduate School regarding the viability of full-duplex underwater acoustic communications. As implementation of full-duplex links requires partitioning the total capacity into distinct sub-channels, the paper presents a top-level description and specification of a capacity allocation protocol to mitigate the adverse impacts of such a partitioning when system load is light.
