DarkVLP: “Lights-Off” Visible-Light Positioning

IEEE Internet of Things Journal, 2022
Visible Light Positioning (VLP) has been considered as a promising indoor positioning technology due to its high precision and low cost. However, current visible light positioning techniques are greatly limited by the assumption that lights have to be turned on to emit shining light beams, which is not applicable to scenarios that do not need the ...

Signature Codes in Visible Light Positioning

IEEE Wireless Communications, 2021
With the explosive development of the Internet of Things (IoT), massive equipments are involved in the indoor environment with the demand of precise localization to provide intelligent interconnection. The visible light positioning (VLP) system, with the light emitting diode (LED) and the photo-diode (PD) or image sensor as the transceiver, has ...

Passive Positioning using Visible Light Systems

Optical Fiber Communication Conference (OFC) 2021, 2021
Passive indoor visible light localization detects changes in illumination patterns in a room to infer the position of a user. We present analytical bounds on positioning error of an object in an indoor scenario and use deep learning to estimate positioning in realistic scenarios.

Polarization-Based Visible Light Positioning

IEEE Transactions on Mobile Computing, 2019
Visible Light Positioning (VLP) provides a promising means to achieve indoor localization with sub-meter accuracy. We observe that the Visible Light Communication (VLC) methods in existing VLP systems rely on intensity-based modulation, and thus they require a high pulse rate to prevent flickering.

Visible Light Positioning in the Presence of Malicious LED Transmitters

IEEE Transactions on Communications, 2023
We consider a visible light positioning system in which a receiver performs position estimation based on signals emitted from a number of light emitting diode (LED) transmitters. Each LED transmitter can be malicious and transmit at an unknown power level with a certain probability.
