Design of a collisonless underwater acoustic network
Proceedings of the Thirteenth ACM International Conference on Underwater Networks & Systems, 2018A 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 ...

An overview on Underwater Acoustic Sensor Networks
2010 17th International Conference on Telecommunications, 2010Underwater 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.

Underwater Acoustic Channels Characterization for Underwater Cognitive Acoustic Networks
2018 International Conference on Intelligent Transportation, Big Data & Smart City (ICITBS), 2018This 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”.

Software-defined underwater acoustic networking platform
Proceedings of the Fourth ACM International Workshop on UnderWater Networks - WUWNet '09, 2009Currently 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

On Securing Underwater Acoustic Networks: A Survey
IEEE Communications Surveys & Tutorials, 2019Underwater acoustic networks (UWANs) are often deployed in unattended and untransparent or even hostile environments and face many security threats, while many applications based on UWANs require secure communication, such as costal defense, submarine communication and harbor security.

Study on MC-CDMA for Underwater Acoustic Networks
2008 International Conference on Computer Science and Software Engineering, 2008In this paper, multiple access technique for the physical layer of underwater acoustic (UWA) networks is discussed. Considering the characteristics of acoustical channel and UWA networks, multi-carrier code division multiple access(MC-CDMA) method is chosen as the multiple access strategy in the design of an UWA network.

A note on CSMA performance in underwater acoustic networks
Computer Communications, 2015Carrier sensing MAC protocols have limited utility in underwater acoustic networks because the propagation delay is not small relative to the packet duration. A recent publication shows simulated results that would appear superior to those predicted by accepted theoretical analysis.
