Performance Analysis of VLC-Based Infrastructure-to-Vehicle Communication

Infrastructure such as traffic signals are expected to communicate various safety messages as a part of the evolution of smart transportation networks. It is anticipated that hybrid Vehicle to Vehicle (V2V) and Infrastructure to Vehicle (I2V) communication links would be taken into account to further enhance the system performance and expand the reach and capacity of the network. This paper proposes a visible light communication (VLC) link by installing multiple Photo-Detectors (PDs) in I2V links in order to improve the Bit Error Rate (BER) performance of the system. The paper investigates the effect of the distances and received powers on the performance of the I2V link used. Additionally, the paper investigates the effect of dimensions and location of the photo-detectors (PDs) on the performance and proposed the best PD distribution and allocation to have the optimum BER performance.
