Hybrid V2X Communication Approach using WiFi and 4G Connections

Abstract

Technology advances in the field of intelligent transportation systems are rapidly increasing due to their crucial importance in saving millions of lives on the roads. One of the main elements to ensure that all road entities are connected is the design of stable and secure communication schemes, which is able to operate under different conditions and constraints. Accordingly, in this paper, a hybrid communication approach is proposed for Vehicle-to-Everything (V2X) communication schemes based on the use of WiFi and 4G connections. The objective is to ensure that the intelligent vehicles are able to maintain the vehicular communication using both connection methods in real-time, based on preadjusted configurations. The configurations include the networks availability, signal strength, and network security, among others. In order to validate the proposed work, several experiments were carriedout using automated vehicle in off-road environment scenario. The obtained results shows the performance of the proposed work to switch from a network to another aiming for the optimization of the shared data speed and steadiness.
