Analysis of intelligent transport system with optical vehicle-to-vehicle communication

In this paper, we introduce an intelligent transport system (ITS) with optical vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication using optical wireless communication (OWC) tech-nology. The vehicles and the roadside units acts as communicating nodes, providing each-other the information regarding vehicles and infrastructure in the vicinity. The LED based optical wireless communication used turns to be effective in short range line-of-sight communication and thus overcoming the limitations incurred due to isotropic nature of radio waves. However, there are significant constraints to OWC used for ITS, which are due to impairments like adverse atmospheric turbulence conditions which degrades the link performance due to irradiance fluctuations. In this paper, we address these limitations and analytically evaluate the symbol error rate (SER) for the considered system with independent and non identically distributed (i.n.i.d.) optical links.
