Vehicular communications in tunnels using VLC

Abstract:

The advances in vehicular communications and Internet of Things (IoT) technologies have provided a promising opportunity to further address the increasing Intelligent Transport System (ITS) issues. In general, ITS coverage in closed spaces is increasingly seen as essential, particularly in road tunnels, where reliable systems are needed. Visible light communication appears as a potential alternative to Radio Frequency (RF) technologies for road tunnels where RF signals face some constraints that severely affect its propagation performance. In this paper we present a VLC communication infrastructure for vehicles taking into consideration the different elements of road tunnels. A feasibility analysis of the proposed system is also shown.
