Densely deployed light emitting diodes (LEDs) typically lead to high spatial correlation in
multiple-input multiple-output (MIMO) visible light communication (VLC) systems. Although …

The underground facilities require to be inspected regularly for long term and safe-use.
Several mobile inspection systems are widely used, but some crucial problems with the …

Autonomous mobile robots operating in areas with poor GPS and wireless coverage (eg,
underwater) must rely on alternative localization and communication approaches. In this …

Abstract Light-Emitting Diode (LED) optical wireless communication is a potentially low-cost,
sustainable approach for enabling high-speed free-space and underwater transmissions …

High-precision positioning of two underwater mobile robots based on laser beams
alignment has been investigated in this work. Usually, the control problem addressed in …

In this paper, a novel laser spot tracking algorithm that incorporates the Kalman filter with the
continuously adaptive Meanshift algorithm (Cam-Kalm) is proposed and employed in an …

Acoustic-based techniques are the standard for localization and communication in
underwater environments, but due to the challenges associated with this medium, it is …

Mobility is one of important issues for line-of-sight visible light communication (VLC). For a
high-speed VLC system, the field of view (FOV) of the transceivers is very narrow for high …

Some fish species communicate electrically (termed electrocommunication) in turbid waters
where other communication modalities fail. Inspired by this biological phenomenon, we …

Abstract Light-Emitting Diodes (LEDs) based underwater optical wireless communications
(UOWCs), a technology with low latency and high data rates, have attracted significant …
