A tabu search-based LED selection approach safeguarding visible light communication systems. (arXiv:2401.13715v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
In this paper, we investigate the secrecy performance of a single-input
single-output visible light communication (VLC) channel in the presence of an
eavesdropper. The studied VLC system comprises distributed light-emitting
diodes (LEDs) and multiple randomly located users (UEs) within an indoor
environment. A sum secrecy rate maximization problem is formulated to enhance
confidential transmission by selecting the optimal LED for each UE. To address
the non-convex and non-continuous nature of this problem, we propose a tabu
search-based algorithm that prevents …
