Abstract
As common tools to validate underwater acoustic network protocols, simulation platforms are challenged by constructing near-real channel model and communication nodes. In this paper, we design a semi-physical simulation platform based on NS3, called Aqua-Psim, to narrow gaps between simulation and sea trial. It combines real modems and software for higher simulation accuracy and network configuration flexibility. Moreover, Bellhop ray-tracing program is employed to provide more authentic propagation process of underwater acoustic signal. In addition, we extend some service functions: data processing, time synchronization and localization for more facilitative user development. Simulation results show that Aqua-Psim is a promising simulator for underwater acoustic networks.
