On Multicasting in Underwater Acoustic Networks
2015 IEEE Global Communications Conference (GLOBECOM), 2014Even though underwater acoustic communication suffers from long propagation delays and has very limited bandwidth, it still plays a key role in supporting long-distance, low-power communication in underwater sensor networks. Many previous studies have tried to mitigate the impact of long propagation delays, but recently, the focus has shifted from ...

IEEE Journal of Oceanic Engineering, 2000
With the advances in acoustic modem technology that enabled high-rate reliable communications, current research focuses on communication between various remote instruments within a network environment. Underwater acoustic (UWA) networks are generally formed by acoustically connected ocean-bottom sensors, autonomous underwater vehicles, and a surface ...

Network-assisted underwater acoustic communications
Proceedings of the Seventh ACM International Conference on Underwater Networks and Systems - WUWNet '12, 2012For 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), 2015This 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, 2011Underwater 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.
