What is it about?
Underwater acoustic communication systems are highly susceptible to faults caused by self-noise, echoing, and message duplication. In this work, a restricted-flooding protocol for reducing message duplication is presented. This method employs random algorithms and adapts concepts of virtual carrier sense to underwater ad hoc networks.

Why is it important?
The communication protocol presented in this work shows a significant decrease in asymptotic message complexity when compared to previously employed techniques. Reducing the total number of duplicate messages results in reduced power consumption and reduced rates of error, resulting in underwater acoustic sensor networks that are more efficient and survive longer.
Perspectives
I view this work as an early endeavor in understanding the performance of underwater acoustic broadcasting networks. I believe this work will lay a foundation for future works that explore acoustic propagation not only as a physical quantity but as a computational quantity. That is to say that there are computationally relevant metrics capable of shedding insight into the performance of underwater acoustic communication networks; and this work provided some early insight into the qualities of those metrics.
