MULTIMEDIA COMMUNICATION USING EFFICIENT LIGHTING SOURCE

Abstract

nowadays, a lot of researchers are working on the development of light-emitting diode (LED) lighting system. The
LED lighting system can achieve lower power consumption and has a longer life-time compared to the fluorescent lamp system.
Li-Fi stands for Light-Fidelity. Li-Fi technology, proposed by the German physicist—Harald Haas, provides transmission of data
through illumination by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. This
paper focuses on developing a Li-Fi based system and analyzes its performance with respect to existing technology. Data transfer
is kind of process to transfer the data between two objects. Data transfer is done by various methods from ancient by paper and
pen as technology develops, transmission is done through wire and further wireless. This technique causes lot of problem like data
losing, hacking of data further cause health hazards to the children by emission of waves in wireless communication. The
objective is to produce lesser data lose and an eco-friendly system. In this paper we outline the basic components in these
systems, review the state of the art and discuss some of the challenges and possibilities for this new wireless transmission
technique.
