Underwater sensor networks (USN) are used for tough oceanographic missions where
human operation is dangerous or impossible. In the common mobile USN architecture …

Localization is one of the most important issues associated with underwater acoustic sensor
networks, especially when sensor nodes are randomly deployed. Given that it is difficult to …

The localization of autonomous underwater vehicles (AUVs) in anchor-free environments
has always been a difficult problem due to the lack of global positioning systems and …

Localization accuracy is crucial for achieving reliable location tagging for underwater
missions. However, the accuracy of conventional range-free localization schemes with a …

Localization refers to the estimated position of each sensor node within a network. It's
necessary since underwater sensor nodes depend on this information for reliable …

Abstract Underwater Acoustic Sensor Networks (UWASNs) connect the resources available
in oceans to the rest of the world. The network has a huge amount of sensors which are …

Localization is an important and extensively studied problem in ad-hoc wireless sensor
networks. Given the connectivity graph of the sensor nodes, along with additional local …

Underwater localization is an important and fundamental part of the Underwater Acoustic
Networks (UANs). The problem we must face is that radio waves and optical waves are …

We transform the 3D underwater sensor network (USN) localization problem into its 2D
counterpart by employing sensor depth information and a simple projection technique. We …

Underwater navigation that relies solely on dead reckoning (DR) suffers from unbounded
position error growth. A common approach for alleviating the problem is to have the …
