Performance analysis of Integrating Wireless Sensor Network with Li-Fi Wireless Communication Technology using OptiSystem Simulation Tool

Abstract

Light Fidelity (Li-Fi) is one of the key areas in wireless communication that works in the same way as optical fiber, but the medium of transmission is free space. The design of a Light-emitting diode (LED) in Li-Fi technology makes changes in the way of communication that can be used for transmitting data by flashing light. On the other hand, sensors nodes in WSNs need photodiodes as a detector which plays an important part in receiving data from a LED and decoding it. Free space optical (FSO) communication has emerged as a feasible technique for broadband wireless applications. In this article, we used two scientific software to analyze the performance of wireless sensor networks with Li-Fi technology: OptiSystem, which is a tool for developing and analyzing optical communication systems, and Matlab which is used to integrate results curves. In this analysis, we consider three models of wireless sensor networks that use photodetectors that receive data from LED throughout the FSO channel: the LOS model, the single LED non-LOS model and the two LED non-LOS model. When compared the models together, the experimental results indicated that the LOS model is the best for WSNs which use Li-Fi technology.
