An Indoor Visible Light Communication Positioning System

Ba is a global optimization algorithm that can be used to solve the indoor positioning problem.

An indoor visible light communication positioning system.

Additionally visible light communication vlc has recently emerged as one of the most promising candidates for fifth generation 5g mobile communications. In ba the positioning process is considered to be a process of searching for the receiver by many bats in an indoor space of 3 x2009 x2009 m x00d7 3 x2009. State of the art. Indoor positioning systems based on visible light communication.

The light can be emitted by an led or a fluorescent tube and has to be received and converted by a photo detector for example a smartphone camera. Advances in visible light communication vlc technology and the ubiquity of illumination facility have led to a growing interest in vlc based indoor positioning. Numerous techniques have been proposed to obtain better system performance. Visible light for communication indoor positioning and dimmable illumination.

The performance of the positioning system is determined by the layout of leds the receiver circuit incidence angle of light led light source and the photodiode. Theoretical accuracy analysis of indoor visible light communication positioning system based on received signal strength indicator. Several other types of wireless signals have been applied in indoor positioning fields such as wifi. Intensity modulation direct detection and carrier allocation methods are utilized in the proposed system.

A three dimensional 3 d positioning system on the basis of bat algorithm ba using visible light communication is proposed in this work. Recently visible light communication vlc has gradually become a research hotspot in indoor environments because its advantages of illumination and relative high positioning accuracy. Indoor positioning systems based on vlc can be used in places such as hospitals eldercare homes warehouses and large open offices to locate people and control indoor robotic vehicles. But unfortunately in the matter of algorithm complexity and positioning accuracy most existing vlc based systems fail to deliver satisfactory performance.

Vlc visible light communication can transfer data by means of light. Vlc visible light communication can be used to set up an indoor positioning system including indoor navigation. We propose a new indoor positioning system utilizing visible light communication. An indoor visible light communication positioning system using a rf carrier allocation technique abstract.

Visible light positioning systems use led lamps to transmit information and their receivers mainly based on photodiodes pds or image sensors. Compared with the traditional indoor positioning methods visible light positioning is advantageous not only with its stability convenience and immunity from electromagnetic interference but also with its positioning accuracy.
