“…Conductivity, Temperature, and Depth -CTD probe) and with an acoustic channel performance predictor to convert these measurements into communication performance. The derivation of the sonar and communication range from environmental and geometric information on the channel is not treated here, but it can be pursued for instance with the approach described in [5]. In this regard, we consider these quantities as available information, and we assume that each agent is able to adapt its depth, when needed, to achieve the desired communication performance.…”

“…In this paper the communication difficulties in agents cooperation are tackled from the application level point of view, i.e., proposing a cooperation strategy that on one side attempts to reduce the information exchange among the nodes, and, on the other side, which is robust with respect to connectivity loss or communication range degradation. The aspects more related to the physics of underwater acoustic propagation have been discussed elsewhere [5], where, in particular, it has been shown how to compute communication figures of merit (bandwidth, signal-to-noise ratio, communication range) from oceanographic environmental properties. In this paper, each node uses the maximum communication range as the available information (if needed computed on board) on the communication channel properties.…”

“…Since the speed of sound can vary greatly in regions of thermocline and halocline, and most AUV missions operate within these regions [8], determining speed of sound accurately is crucial. Propagation loss is composed mainly of three aspects, namely, geometrical spreading, attenuation by absorption and the anomaly of propagation.…”

“…Acoustic‐based support systems typically have coverage in the range of 100 m to 10 km with positioning accuracy from centimetres to few metres. However, acoustic signals can only propagate approximately 100 km underwater with sufficient bandwidth for phase‐coherent communication (Caiti, Crisostomi, & Munafò, ; Freitag, Koski, Morozov, Singh, & Partan, ). The range primarily depends on the frequency of the signal, and hence a trade‐off must be made.…”
