Optimal Fair Scheduling in S-TDMA Sensor Networks for Monitoring River Plumes
Luque-Nieto, Miguel Ángel
; Moreno-Roldán, José Miguel; Poncela-González, Javier; Otero-Roth, Pablo (Hindawi Publishing Corporation, 2016)
Underwater wireless sensor networks (UWSNs) are a promising technology to provide oceanographers with environmental data in real time. Suitable network topologies to monitor estuaries are formed by strings coming together ... -
Proof of Concept of the Use of the Parametric Effect in Two Media with Application to Underwater Acoustic Communications.
(MDPI, 2023-08-15)Nonlinear acoustics offers a new range of acoustic applications that are currently being exploited. The parametric nonlinear effect—the occurrence of low frequencies with modulated high-frequency emission—is of particular ... -
Underwater Positioning System Based on Drifting Buoys and Acoustic Modems
Otero-Roth, Pablo; Hernández-Romero, Álvaro; Luque-Nieto, Miguel Ángel; Ariza-Quintana, Alfonso (MDPI, 2023-03-23)
GNSS (Global Navigation Satellite System) positioning is not available underwater due to the very short range of electromagnetic waves in the sea water medium. In this article a LBL (Long Base Line) acoustic repeater system ... -
Wideband Ultrasonic Acoustic Underwater Channels: Measurements and Characterization.
López-Fernández, Jesús Manuel; Fernández-Plazaola, Unai; París-Ángel, José Francisco; Díez-del-Río, Luis; Martos-Naya, Eduardo (IEEE, 2020-02-12)
In this work we present the results of a measurement campaign carried out in the Mediterranean sea aimed at characterizing the underwater acoustic channel in a wideband at ultrasonic frequencies centered at 80 kHz with ...
