Architectural building protocols for Li-Fi (light fidelity)

Abstract

Light fidelity commonly known as Li-Fi is the technology emerged from visible light communication (VLC) that allows to transmit data through illumination, i.e., through light emitting diode (LED). Li-Fi varies in intensity faster than human eye to be followed, and therefore, Li-Fi is known for high data speed. With the increase in the number of wireless gadgets such as smartphones, tabs, smart wrist watches, etc., Li-Fi will surely be an incredible companion of Wi-Fi and an interesting subject for research. Therefore, in this chapter, we cover the evolution of Li-Fi, its architecture, requirement of Li-Fi, and its challenges. We also discuss the integration of Li-Fi protocols with existing protocols for integrated communication and conclude the chapter with the future scope of Li-Fi in the Internet. © Springer Nature Singapore Pte Ltd. 2018.
