Study on the Status and Prospect of Underwater Acoustic Communication and Networking

Underwater acoustic communication is the main wireless information transmission technique in the ocean. It is widely used in ocean environment observation and operations of underwater vehicles and manned submersibles. Meanwhile, the adverse operation conditions at sea and rapidly changing transmission state of underwater acoustic channels require high reliability of the communication devices and high performance of the communication algorithms. Underwater acoustic communication and networking has become a research focus. This paper concentrates on the field of marine environment monitoring, introduces the physical layer technology, network technology and networking application of underwater acoustic communication, as well as discusses the development trend of underwater acoustic communication and networking technology.
