Abstract
We investigate the secrecy connectivity in visible light communication in the presence of randomly located eavesdroppers. We apply spatial point processes to characterize the unknown eavesdropper locations. The closed-form of the secrecy outage probability is derived as a function of the density of eavesdroppers. The analysis is verified by Monte Carlo simulations. Furthermore, we suggest an LED transmitter selection scheme based on the location of a legitimate user. It is verified that the proposed transmission scheme can significantly improve the secrecy performance as a function of the number of LED transmitters.
