This presentation explores vehicular ad hoc networks (VANETs) as a key component of intelligent transportation systems, enabling safer and more efficient road traffic through communication between vehicles and infrastructure. With the growing use of UAVs in urban environments, this work examines how vehicles and drones can cooperate to form a unified communication network. I introduce three routing approaches designed to improve inter‑vehicle communication in urban areas: a connectivity‑based routing method assisted by UAV supervision, a dual‑layer routing scheme separating ground and aerial communication, and a reactive routing strategy that predicts route expiration times. Simulation results highlight the strengths and limitations of these approaches and demonstrate their potential to enhance reliable end‑to‑end communication in VANETs.
