This paper presents mathematical modeling for combined attenuation response of acoustic signal travelled through multiple sink nodes from a source node to a destination node for shallow water applications. The link was considered for an imaginary underwater sensor network having 5 nodes including source node, destination node and transceivers with same communication range. The speed of sound wave is less compared to EM wave so delay introduced at receiving side due to channel geometry and attenuation occurred due to refraction and reflection from sea surface and bottom respectively. Thus achieving high rate communication for wide range of channel geometry is little bit tough so it is better to study mathematical phenomenon behind such a communication link to proceed towards precision. The simulation of multipath model scenario acoustic sensor network of was made with the help of Matlab and the results were found satisfactorily.
