Li-Net: towards a smart Li-Fi vehicle network

Abstract

Light Fidelity is popularly known as Li-Fi. This is a very new technology that is driven by German physicist Harald Haas [1] in 2011. The technology is proposed during a global talk on Technology Entertainment Design on VLC communications. Visible light communications are optical ways of communication that networks the LED for data transmission. The term Li-Fi uses the VLC communication for the high end communication that can be an alternative of Wi-Fi. The proposal of Harald Haas is comparable with IEEE 802.15.7 that is fully dual directional and networked standard built for 802.11. Li-Fi applications are featured for their comparison with other technologies like Wireless fidelity and their general use for LAN. However the optimality of the proposed Li-Fi is with in highly dense areas where WiFI faces interfaces and radio interferences are no good for complimentary performance goals of the communication standard. Li-Fi proves to be better in band width, connectivity and secure when the higher speeds above than 1Gbps are achieved. This paper outlines the characteristics of Li-Fi and describes its potential use in a smart traffic net. The smart traffic net is future of transport system that is based on Li-Fi. Therefore this is called as Li-Net in this paper. Li-Net is modified VaNet that uses Li-Fi for V2V and V2I communication. The leveraging of Low cast LEDs and other lighting units there are lots of opportunities that can help the Li Fi to get over Wi Fi.
