Channel model simulation for underwater acoustic sensor networks using OPNET

Underwater acoustic sensor networks (UWA-SNs) have attracted great attentions owing to their important underwater applications for military and commercial purposes The practical deployment and design of UWA-SNs face some special challenges, one of which is the accurate channel model for simulation. This paper provides details of the implementation of a channel model simulation using OPNET, with respect to Propagation-Delay-Stage, Receiver-Power-Stage and Background-Noise-Stage, and designs a simple project of two nodes with different distances to validate its accuracy that simulation results have shown.
