Fuzzy Logic Based Network Selection in Hybrid OCC/Li-Fi Communication System

Abstract

For being highly energy efficient and inexpensive, the use of current commercial LEDs for transmitting data is considered as a significant milestone in the area of optical wireless communications. Light-fidelity (Li-Fi) and optical camera communications (OCC) are two latest technologies which use LED as transmitter, with PD and camera as receivers, respectively. Currently, Li-Fi is emerged as highly promising as it supports high data rate and security. But it suffers from some limitations, e.g., short communication distance, low signal-to-interference-plus-noise ratio (SINR) etc. OCC can overcome these limitations, but it only supports lower data rate. Therefore., to provide proper solution, we propose a hybrid OCC/Li-Fi system. We are not going to use both the technologies at the same time, rather access point is selected based on fuzzy logic, considering different application scenarios. Furthermore, at the end of this paper, the performance of the selection mechanism is discussed briefly.
