VeFog - Efficient Message Dissemination in VANETs based on Edge, Fog and Cloud Computing

Technological progress has had a dramatic impact on the automotive industry and the concept of intelligent and connected vehicles is developing rapidly. Vehicles are being equipped with various in-vehicle and environmental sensors that generate huge amounts of data, as well as onboard units that can calculate, store and communicate data with other vehicles, infrastructure and the environment. This has led to the development of Vehicular Ad-hoc Networks (VANETs), which face various challenges due to a heterogeneous and highly dynamic environment, where traditional solutions need to be improved and adapted to meet the networking and processing requirements. The integration of edge and fog computing in VANETs reduces the overhead by placing the necessary resources at the edge of the network closer to the information source. In this paper, we propose VeFog - the new architecture based on edge and fog computing for efficient data processing and dissemination in VANETs. The performance evaluation and simulation results show that the VeFog architecture is efficient, reduces processing time and saves resources with minimal infrastructure utilization.
