Operation of VANET Communications

Abstract

This work proposed an integrated novel architecture of UAV System, LTE/4G, and WAVE technologies with its forwarding schemes in highway scenario to enhance the VANET communications and achieve the requirements of its basic applications, particularly safety and traffic. Algorithms for UAV sensing, tagging (based on the proposed safety and traffic info model), and broadcasting operations, and forwarding of safety or traffic info to respective infrastructures, and then smart ground vehicles are designed, particularly to minimize intermittent connectivity and bandwidth usage as well as to satisfy the requirements of VANET applications. The authors have evaluated the performance of the integrated novel architecture with its forwarding schemes/algorithms through integrated and simulated VANETs and wireless access technologies (LTE/4G and UAV system) environment.
