VLC Enabled Foglets Assisted Road Asset Reporting

There has been a lot of work on emergency reporting in smart transportation systems, but we find less information about road side asset reporting and management. Currently available mechanisms do not efficiently handle asset management and associated emergency reporting. Asset management is based on either reactive maintenance (reported by people) or preventative scheduled maintenance (scheduled). In this article, we present a reporting architecture for emergency situations and, management through Foglets and visible light communication (VLC). We propose the use of Foglets near road sides to improve information processing and Quality of Service (QoS) and to reduce communication delay. We use the VLC link between Foglets and smart vehicles and discuss its safety and suitability for the road assets infrastructure, as compared to conventional RF links. We model this VLC link and discuss its luminosity and BER characteristics.
