Selection of communication carrier for underwater wireless sensor networks

Wireless communication in underwater environment is becoming increasingly important and has gained attention as a theme of research. Acoustic communication in underwater environment is the most mature technology for underwater sensor networks (UWSNs). This paper presents a brief overview on the basics of underwater communication with communication architecture, including selection of communication carrier for UWSNs. The paper also provides an outline of challenges in building UWSNs. Finally, simulation based experimental results are presented to compare performance of communication carriers emphasizing on their propagation speed.
