A Shared Underwater Network emulAtion dataset (ASUNA)

The underwater channel is a fast frequency-selective-time-varying environment that is hard to model. For this reason, a reliable comparison of algorithms and protocols designed for UWAN is challenging, and common approaches rely mostly on sea experiments for performance validation. Yet, while experiments represents well the performance in the instantaneous tested environment, they cannot validate performance over a verity of scenarios. In particular, robustness to sea conditions and to network topology structures cannot be explored via a singular test point. Considering this challenge, we share our database of recorded time-varying topologies in multiple sea experiments with the aim that this will serve as the benchmark to test and compare UWAN solutions. Our database is very diverse, including multiple time-varying topology structures, multimodal communication technologies, and a verity of link quality measures. The database will be extended as new data becomes available from the UWAN community. We provide the details of the database structure, the list of recorded topologies, and an example on how to use the database as an emulation system to test in-lab the performance of a scheduling protocol in a realistic scenario. We freely share both the database information and description and the emulation code over a designated web server.
