چکیده
This paper present simulation-based results on the impact of transmitter (Tx) position and orientation uncertainty accuracy visible light positioning (VLP) system based received signal strength (RSS). There are several constraining factors for RSS-based algorithms, particularly due to multipath channel characteristics set-up uncertainties. The Tx uncertainties error performance is studied, assuming a statistical modelling Simulation show that have severe error, which can be leveraged through usage more transmitters. Concerning smaller Tx’s 5 cm, average errors 23.3, 15.1, 13.2 cm with standard deviation values 6.4, 4.1, 2.7 4-, 9-, 16-Tx cases, respectively. While Tx’ 5°, 31.9, 20.6, 17 9.2, 6.3, 3.9

A Visible Light Based Indoor Positioning System
In this paper, we propose a novel indoor localization scheme, Lightitude, by exploiting ubiquitous visible lights, which are necessarily and densely deployed in almost all indoor environments. We unveil two phenomena of lights available for positioning: 1) the light strength varies according to different light sources, which can be easily detected by light sensors embedded in COTS devices (e.g....
متن کاملEpsilon: A Visible Light Based Positioning System
Exploiting the increasingly wide use of Light-emitting Diode (LED) lighting, in this paper, we study the problem of using visible LED lights for accurate localization. The basic idea is to leverage the existing lighting infrastructure and apply trilateration to localize any devices with light sensing capability (e.g., a smartphone), using LED lamps as anchors. Through the design of Epsilon, we ...
متن کاملIndoor Positioning and Pre-processing of RSS Measurements
Rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. Among different techniques, RSS-based schemes and in particular oneof its variants which is based on Graph-based Semi-Supervised Learning (G-SSL) are widely-used approaches The superiority of this scheme is that it has low setup/training cost and at the same ti...
متن کاملAsynchronous indoor positioning system based on visible light communications
Indoor positioning has become an attractive research topic within the past two decades. However, no satisfying solution has been found with consideration of both accuracy and system complexity. Recently, research on visible light communications (VLC) offer new opportunities in realizing accurate indoor positioning with relatively simple system configuration. An indoor positioning system based o...
