Abstract : Li-Fi is a new method of sending and receiving secure data using light energy from one node to another. When data are transferred to the receiver node, the sender’s node light will blink continuously in the decade research. This may appear to be an uncomfortable remote control. Other than that, there are disadvantages to using a Wi-Fi network for the node because it has significant drawbacks such as bandwidth variances between nodes when using the communications system, such as some nodes achieving actual transmission speeds and others having low data rates. Li-Fi solves this issue by using light energy similar on both the sender and receiver sides, so the receiver node can transfer data at high speeds even when the device sending it is far away. The data transfer speed will be 9600 bits per second, which is fast enough to prevent lagging. The Li-Fi system has mainly been used in wireless nodes and IoT devices with embedded technology, a colour sensor and a microcontroller. The virtual node’s light source communicates with the destination nodes’ colour sensor, transforming the light into digital information. For the most part, these apps are found in IoT devices for user needs.
