Abstract
Underwater Wireless Sensor Networks (UWSNs) find numerous applications, like underwater monitoring & exploration, water quality analysis, offshore oil field monitoring, oceanographic data collection etc. All these aquatic applications need to observe & predict the ocean characteristics. The conventional methods used for terrestrial domain cannot be applied here as there exist some architectural differences in the underwater environment, mainly due to variations in the transmission medium. In this paper, we have analyzed the acoustic channel characteristics like attenuation, noise and speed of sound (propagation speed) with variations in frequency, depth, salinity, temperature etc. by applying different models and equations for UWSNs.
