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

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.

Channel simulation for underwater acoustic communication network
Proceedings of the Seventh ACM International Conference on Underwater Networks and Systems - WUWNet '12, 2012Significant advancements in underwater acoustic communication have been achieved in recent decades. In the dynamic ocean environment, various physical processes can significantly affect the communication channel. The time-varying underwater channel has both deterministic and stochastic features. Due to the dynamic environment and the complex properties
