Underwater Sensor Networks

open access: yes, 2016
Underwater sensor networks (UWSNs) are mobile ad hoc networks that present the opportunity for many applications, such as coast surveillance, four-dimensional monitoring such as for ocean and biology studies, and oil and gas field monitoring. The chapter presents the current state of the art of UWSNs.
