In this paper, the authors compare communication schemes in scenarios of interest for underwater networks where multiple nodes collaborate towards the accomplishment of a target detection and tracking task. They consider two specific cases: a mobile Autonomous Underwater Vehicle (AUV) collects data from a set of fixed sensors deployed on the seafloor or transmits data to the same nodes. Two AUVs are placed at opposite sides of an area to be patrolled, and move in the same direction. Some low-complexity, relay-only AUVs keep moving in between edge AUVs in order to support networked data exchange between them.
