Indoor Positioning System Using Visible Light Communication

By comparison vlp has such advantages as cost saving environmentally friendly anti rf interference and so on which.

Indoor positioning system using visible light communication.

The technology uses fluorescent lamps ordinary lamps not special communications devices to transmit signals at 10 kbit s or leds for up to 500 mbit s over short distances. Moreover visible light communications technology enables users to find out which floor they are located on. This paper analyzes an indoor positioning system using white lighting leds. Theoretical accuracy analysis of indoor visible light communication positioning system based on received signal strength indicator abstract.

Abstract a novel indoor positioning approach using entities of the visible light communication system as anchor points and tags is presented. Vlc is a subset of optical wireless communications technologies. The indoor positioning system by visible light com munication wireless. When using visible light communication it becomes possible to identify the user s position within a range of 1 2m.

Indoor visible light communication positioning system using a rf carrier allocation technique j ournal of lightwave technology vol. But unfortunately in the matter of algorithm complexity and positioning accuracy most existing vlc based systems fail to deliver satisfactory performance. Different from conventional indoor positioning technologies mentioned above the visible light positioning vlp technology is a kind of indoor positioning technology based on visible light communication vlc technology. Recently visible light communication vlc has gradually become a research hotspot in indoor environments because its advantages of illumination and relative high positioning accuracy.

A highly accurate indoor positioning under the effect of multipath reflections has been a prominent challenge for recent research. Communication technology using led lights. The performance of the positioning system is determined by the layout of leds the receiver circuit incidence angle of light. This paper proposes a novel indoor visible light communication vlc positioning model by connecting k nearest neighbors knn and random forest rf algorithms for reflective environments namely knn rf.

1 1 visible light communication vlc based indoor positioning system ips research on visible light communication vlc was begun about 10 years ago according to the published date of tanaka et al. During that time the research on vlc was not popular mainly because of the high production cost of led. Visible light communication vlc is a data communications variant which uses visible light between 400 and 800 thz 780 375 nm.
