Introduction Autonomous underwater vehicles (AUVs) are required to thoroughly scan
designated areas during underwater missions. They typically follow a zig-zag trajectory to …

UWSN refers to a collection of numerous underwater wireless sensor-nodes dispersed
throughout the marine environment. Proposed work develops node-localization and optimal …

Underwater navigation is a challenging problem in the field of Autonomous Underwater
Vehicles (AUVs) due to significant electromagnetic wave attenuation and uncertainties in the …

To solve the effect of unreliable acoustic range measurements in cooperative localization of
autonomous underwater vehicles, a novel localization method is proposed by using a hybrid …

Underwater optical wireless communication (UOWC) has received increasing attention due
to its distinctive characteristics such as high bandwidth and low latency. However, the …

The ocean covers 70. 8% of the Earth's surface, and it plays a significant role in supporting
the system of life on Earth. Nevertheless, more than 80% of the ocean's volume remains …

Localization of underwater networks has received lots of attention. However, existing
scheme focuses on establishing a relative topology where a node's position is defined in …

Underwater acoustic localization is an important, yet challenging problem:(1) node mobility
issue,(2) Doppler effect, and (3) clock imperfection. To be specific, underwater nodes are not …

The stratification effect underwater can lead to the localization errors in underwater acoustic
sensor network. In order to compensate the stratification effect and improve the localization …

It has been recognized that the performance of the traditional direction of arrival (DOA)
estimation algorithms is highly dependent on array geometry parameters, especially the …
