Localization in Underwater Sensor Networks

Ocean covers 70.8% of the Earth's surface, and Underwater Sensor Networks (USNs) are emerging as a promising solution to understand and explore it. However, underwater localization is challenging due to the openness and weak communication characteristics of USNs. This book focuses on the localization problem in USNs, taking into account the unique characteristics of the underwater environment. It introduces the network architecture of USNs, reviews previous approaches, considers asynchronous clock, node mobility, stratification effect, privacy preserving, and attack detection, and develops corresponding localization schemes. The results reveal that underwater localization accuracy is closely related to the communication protocol and optimization estimator, and the book provides valuable information, useful methods, and practical algorithms to help understand and explore the ocean.

The vast expanse of the ocean, covering approximately 70.8% of the Earth's surface, holds immense significance in sustaining all life on our planet. Despite its vastness, over 80% of its volume remains unmapped, unobserved, and unexplored. In this context, Underwater Sensor Networks (USNs), characterized by their ubiquitous computation, efficient communication, and reliable control, emerge as a promising solution for understanding and exploring the ocean's depths. However, the unique characteristics of USNs, such as their openness and weak communication capabilities, pose significant challenges in underwater localization, unlike their terrestrial counterparts.

In this book, we delve into the localization problem in USNs, considering the distinct features of the underwater environment. This problem holds immense importance, as there is currently limited guidance available for designing and analyzing USN localization schemes. To address this, we first introduce the network architecture of USNs and provide a brief review of previous approaches to localization. Subsequently, we examine key factors such as asynchronous clock synchronization, node mobility, stratification effect, privacy preservation, and attack detection, and develop corresponding localization schemes.

Furthermore, the book's rich implications offer valuable insights into the design of future USN localization schemes. Our findings reveal that underwater localization accuracy is closely linked to the communication protocol and optimization estimator. Researchers, scientists, and engineers in the field of USNs can greatly benefit from this book, which provides a comprehensive wealth of information, useful methods, and practical algorithms to facilitate their understanding of underwater localization.
