An ultra-low power and flexible acoustic modem design to develop energy-efficient underwater sensor networks

Sánchez Matías, Antonio María; Blanc Clavero, Sara; Yuste Pérez, Pedro; Perles Ivars, Ángel Francisco; Serrano Martín, Juan José (MDPI, 2012)

This paper is focused on the description of the physical layer of a new acoustic modem called ITACA. The modem architecture includes as a major novelty an ultra-low power asynchronous wake-up system implementation for ...
Anomaly Detection in UASN Localization Based on Time Series Analysis and Fuzzy Logic

Das, Anjana P.; Thampi, Sabu M.; Lloret, Jaime (Springer-Verlag, 2020-02)

[EN] Underwater acoustic sensor network (UASN) offers a promising solution for exploring underwater resources remotely. For getting a better understanding of sensed data, accurate localization is essential. As the UASN ...
Event-Driven Data Gathering in Pure Asynchronous Multi-Hop Underwater Acoustic Sensor Networks

Blanc Clavero, Sara (MDPI AG, 2020-03)

[EN] In underwater acoustic modem design, pure asynchrony can contribute to improved wake-up coordination, thus avoiding energy-inefficient synchronization mechanisms. Nodes are designed with a pre-receptor and an acoustically ...
Underwater Acoustic Wireless Sensor Networks: Advances and Future Trends in Physical, MAC and Routing Layers

Climent Bayarri, José Salvador; Sánchez Matías, Antonio María; Capella Hernández, Juan Vicente; Meratnia, Nirvana; Serrano Martín, Juan José (MDPI AG, 2014)

[EN] This survey aims to provide a comprehensive overview of the current research on underwater wireless sensor networks, focusing on the lower layers of the communication stack, and envisions future trends and challenges. ...
Underwater Sensor Networks: A New Energy Efficient and Robust Architecture

Climent, Salvador; Capella Hernández, Juan Vicente; Meratnia, Nirvana; Serrano Martín, Juan José (MDPI, 2012)

The specific characteristics of underwater environments introduce new challenges for networking protocols. In this paper, a specialized architecture for underwater sensor networks (UWSNs) is proposed and evaluated. Experiments ...
