We demonstrate the use of the Sapienza University networking framework for underwater Simulation Emulation and real-life Testing (SUNSET) through the implementation and validation of a novel time synchronization and localization algorithm for Underwater Acoustic Sensor Networks (UASNs). The algorithm, implemented and tested in a multi-hop acoustic network, is based on node discovering and cooperation for range estimation and for achieving network level synchronization. Our demonstration shows the flexibility of SUNSET in providing a framework for simulation, emulation and in field testing over heterogeneous devices, including mobile ones. SUNSET enables the users to control network devices remotely for configuration and re-programming, and allows to use the same code for both simulation and actual tests. A video of a SUNSETbased remotely controlled submarine AUV will be shown from previous in field experimentation.
