Network-assisted underwater acoustic communications

Proceedings of the Seventh ACM International Conference on Underwater Networks and Systems - WUWNet '12, 2012
For many underwater acoustic applications, the source and receiver systems carry a single transducer antenna. The lack of spatial diversity makes it difficult to carry out phase coherent communications. Using distributed nodes of an underwater acoustic network, this paper address phase coherent underwater acoustic communications using source diversity.

Eavesdropping attacks in underwater acoustic networks

2015 10th International Conference on Information, Communications and Signal Processing (ICICS), 2015
This paper investigates the eavesdropping attacks in underwater acoustic networks (UANets). In particular, we propose an analytical framework to model the eavesdropping attacks in UANets in terms of the eavesdropping probability. Results of extensive simulations match the analytical results, indicating the effectiveness and accuracy of our model ...

Scheduling granularity in underwater acoustic networks

Proceedings of the Sixth ACM International Workshop on Underwater Networks - WUWNet '11, 2011
Underwater acoustic networks have many distinct channel characteristics when compared to terrestrial networks. Long propagation delay, one such characteristic, allows scheduling methods with varying granularity that tradeoff schedule quality with protocol overhead.

An overview on Underwater Acoustic Sensor Networks

2010 17th International Conference on Telecommunications, 2010
Underwater Acoustic Sensor Networks (UW-ASNs) is of growing research interest. This paper gives description on underwater channel model. It overviews transmission schemes in data link layer and network layer, and simulates different transmission schemes. Finally, it offers comparison and guides for future development.

Design of a collisonless underwater acoustic network

Proceedings of the Thirteenth ACM International Conference on Underwater Networks & Systems, 2018
A hardware solution for a collisonless underwater acoustic networks is proposed in this paper. Each node will be equipped with a horizontal circular array, by which signals from different sources located at different look directions, or bearings, will be extracted by beamforming with little interference from signals from sources at other directions ...

Underwater Acoustic Channels Characterization for Underwater Cognitive Acoustic Networks

2018 International Conference on Intelligent Transportation, Big Data & Smart City (ICITBS), 2018
This paper focuses on characterizing underwater acoustic (UWA) channels in the view of underwater cognitive acoustic networks. In the most recent years, underwater cognitive acoustic networks have attracted much attention in pace with that “digital ocean” is developing to “smart ocean”.

A cooperative protocol for pervasive underwater acoustic networks

Wireless Networks, 2021
The novel Underwater Wireless Sensor Network (UWSN) can contribute to monitor and explore aquatic environments. But, communicating in these environments is still hard and has many challenges. For example, optical and electromagnetic waves deteriorate from high-attenuation.

Software-defined underwater acoustic networking platform

Proceedings of the Fourth ACM International Workshop on UnderWater Networks - WUWNet '09, 2009
Currently acoustics is the primary modality for underwater communication even though it presents a difficult channel. To try and cope with the challenges of the channel many MAC protocols and PHY layer techniques have been proposed. In this paper we present a research platform that allows developers to easily implement and compare their protocols in an

Management of Surveillance Underwater Acoustic Networks

2016
A Surveillance Underwater Acoustic Network (SUAN) is a sensor network specialized in the detection of sea surface or subsurface physical intruders, e.g., seagoing vessels. Network management provides the ability to remotely monitor and update the state of SUAN nodes.
