Cooperative Positioning in Underwater Sensor Networks
IEEE Transactions on Signal Processing, 2010We consider cooperative positioning using acoustic range measurements for underwater sensor networks, including networks formed by autonomous unmanned underwater vehicles (UUVs). Severe multipath scattering from the seabed and ocean surface can result in inaccurate range measurements.

Network coding in Underwater Sensor Networks
2013 MTS/IEEE OCEANS - Bergen, 2013In this paper, we expand upon previous work in the application of network coding to Underwater Sensor Networks (UWSN). Network coding allows information from multiple packets to be encoded into a single packet and decoded upon receiving sufficient linearly independent encoded packets, improving throughput and providing redundancy for error recovery ...

Differentiated Underwater Sensor Network Deployment
OCEANS 2007 - Europe, 2007Underwater sensors technology has experienced a tremendous development over the last decade. They have generated considerable community enthusiasm, which applied them to a wide range of cases that could enhance human and animal habitat conditions e.g. climate changes prediction or pollution surveillance. In this paper, we address the issue of deploying

Simulation of underwater sensor networks
Oceans '99. MTS/IEEE. Riding the Crest into the 21st Century. Conference and Exhibition. Conference Proceedings (IEEE Cat. No.99CH37008), 2003This paper highlights some of the key areas of investigation in the network design and analysis of the Deployable Autonomous Distributed System (DADS). DADS is an exploratory research program sponsored by the Office of Naval Research. Simulation was essential in providing system trade-offs and parametric studies of critical system functions.

Feedback-Based Target Localization in Underwater Sensor Networks: A Multisensor Fusion Approach
IEEE Transactions on Signal and Information Processing over Networks, 2019This paper investigates the problem of target localization in underwater sensor networks, subjected to limited measurement range and accuracy. The localization process is mainly divided into two phases, i.e., distance estimation and position solving.

Weighted Localization for Underwater Sensor Networks
2014ELSN (Efficient Localization for large-scale underwater Sensor Networks) gets the node location by solving equations. However, sometimes the unique solution (no solution or multiple solutions) cannot be obtained from equations because of measurement error. In this case, the node cannot be located.
