Analysis of acoustic channel in underwater acoustic sensor network

The area of underwater acoustic sensor networks (UWASN) is developing expeditiously as it shows a major aspect in various military and civilian practices, such as avoidance of disaster, diplomatic vigilance, seaward analysis, environmental monitoring, oceanographic data collection and mine reconnaissance. There are numerous challenges in UWASN posed by underwater acoustic propagation channel, which includes gradual propagation of acoustic waves, bounded bandwidth, immense and irregular propagation delay, ambient noise and transmission loss. This paper provides the analysis on the working of an acoustic channel in conditions of sound speed and transmission loss using MATLab simulation. The parameters analyzed are absorption coefficient, propagation delay and sound speed at various depth and transmission loss.
