To solve the problem of unknown noise covariance matrices inherent in the cooperative
localization of autonomous underwater vehicles, a new adaptive extended Kalman filter is …

For underwater acoustic (UWA) communication in sensor networks, the sensing information
can only be interpreted meaningfully when the location of the sensor node is known …

In underwater sensor localization scenes, beacon nodes (BNs) with known coordinates are
deployed to localize unknown nodes (UNs). However, the BNs are likely to drift due to …

Precise underwater localization has been very challenging due to the unsynchronized clock,
stratification effect, and anchor location uncertainties. Although some localization methods …

Autonomous Underwater Vehicles (AUVs) have widely deployed in marine investigation and
ocean exploration in recent years. As the fundamental information, their position information …

We present a method for infrastructure-free localization of underwater vehicles with
multibeam sonar. After constructing a large scale (4 km), high resolution (1 m) bathymetric …

Navigating autonomous underwater vehicles (AUVs) in shallow and harbor waters is
challenging and typically has higher accuracy requirements than navigation in the open sea …

Applications of underwater sensors networks (USN) include environmental ocean/sea
monitoring, underwater mine searching, detection of chemically/biologically harmful …

Recently underwater acoustic sensor networks (UASNs) have drawn much attention
because of their great value in many underwater applications where human operation is …

In this paper, we propose a Multi-Anchor Nodes Collaborative Localization (MANCL)
algorithm, a three-dimensional (3D) localization scheme considering anchor nodes and …
