A novel binary encryption algorithm for navigation control of robotic vehicles through visible light communication

Scarcity in radio frequency spectrum has increased the demands for alternate sources of communication medium out which visible light communication (VLC) is quite notable. VLC works by exploiting the abundance in availability of light as an effective means of communication medium. This principle known as Li-Fi or light fidelity conveys information in the form of light pulses modulated with information signals collected by a suitable detector. The objective of this research article is to ensure a secured wireless communication channel using light as the medium. Communication through a wireless medium necessitates appropriate security mechanisms for data being transmitted. In the proposed work, a binary encryption algorithm (BEA) has been tested in a multi-node environment using a mobile robotic vehicle. Data transmitted through the medium contain instructions to navigate the motion of the vehicle. The algorithm simple yet powerful with precise encryption observed from the results.
