Acoustic tomography with an underwater sensor network

2012 Oceans, 2012
Underwater acoustic tomography is a known technique that is traditionally used at large scales to gather temperature and current data about the oceans. Performing acoustic tomography underwater is desirable because it permits information to be derived about the properties of the water between senders and receivers, thus increasing the spatial ...

Distributed cooperative transmission for underwater acoustic sensor networks

2013 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2013
In this paper, we propose a cooperative transmission scheme for underwater acoustic sensor networks to enhance the network performance. Relay nodes are exploited as virtual antennas to achieve diversity gains. Based on the distinct characteristics of the underwater channel such as high transmission loss, propagation delay, and ambient noises, the paper
