This research looks at the security performance of a single-input single-output visible light communication (VLC) channel in the presence of an eavesdropper. The VLC system consists of distributed light-emitting diodes (LEDs) and multiple randomly located users within an indoor environment. The study proposes a tabu search-based algorithm that prevents entrapment in local optima by organizing the trial vectors from previous iterations. The results show that the secrecy performance of the proposed algorithm is close to the global optimal value and surpasses that of the other strategies.
