Dynamic Modem Adaptation in Underwater Networks using Network Knowledge

This paper introduces an underwater modem adaptation based on channel descriptors and network layer knowledge. One topic in the EDA-SALSA project is smart adaptivity. We take the smart approach of not only looking at single links between nodes but exploiting the network as a whole. With awareness of existing neighbors and all their feedback, each node can conFigure itself specifically for the best acoustic transmissions tuned to the environment. The development and implementation were also successfully tested in simulations and a sea trial in the Oslo Fjord in May 2022.
