The recent need of a fully autonomous car has pushed researchers into developing applications, services and technologies capable of connecting the vehicle to its surroundings. A real-time geo-referenced notification system coupled with aggregation of data and optimization of fog-computations in the edge network allows for a fast and reliable traffic orchestration in critical areas. Modern literature showcases the efficiency and responsiveness of cellular vehicle-to-network in areas like collision avoidance and traffic control. This thesis aims at developing an architecture capable of aggregating and disseminating real-time notification messages through a multi-MAC infrastructure. Furthermore, an assessment on its efficiency and responsiveness is carried out through several metrics.
