Comparative Evaluation of Acoustic Channel Characteristics for Reliable Design of Underwater Acoustic Sensor Networks (UASN)

Due to unexplored but desirable undersea resources, Underwater Sensor Network, is developing technology and becomes a catchword for modern scientists. Underwater Acoustic Sensor Networks, also known as UASN, are employed for a broad range of underwater utilizations such as reconnaissance by the military, mineral ore detection, oil reservoir management, aquatic environment exploration, imaging marine life, and early warnings to prevent a natural disaster. Almost every application is triggering to monitor important characteristics such as the salinity concerning different levels of depth, temperature profile, pollutants, etc. However, the study of aquatic channel characteristics is required before implementing the UASN for any of the applications. This research paper presents the underwater channel characteristics by varying the acoustic signal frequency, underwater depth levels, and separation between nodes. The simulated result is generated using MATLAB. The findings in the form of graphical representations are satisfactory and may be considered for future research in UASN.
