A Platoon-Based Vehicle-to-Vehicle Connectivity Enhancing Scheme Under Bidirectional Highway Scene

The connectivity of vehicle-to-vehicle (V2V) communication is critical for efficient data sharing among vehicles. However, the vehicles moving in opposite direction show worse connectivity. To address this issue, a platoon-based V2V connectivity enhancing scheme under bidirectional highway scene is proposed in this paper. First, a typical bidirectional highway scene is investigated to ensure a comprehensive analysis of the connectivity probability among vehicles. Second, a time correlation expression of vehicle movement is derived based on the platoon-based expected lifetime model which is presented. Finally, compared with one popular dynamic clustering scheme in bidirectional road scenarios, the simulations validate the superior performance of the proposed scheme.
