Recent research in multipath routing for Vehicular Ad Hoc Networks (VANETs) focuses on developing adaptive and reliable routing protocols that can handle frequent topology changes, high vehicle mobility, and variable link conditions. Multipath routing enhances data delivery by establishing multiple concurrent or backup paths between source and destination nodes, improving fault tolerance and load balancing. Modern approaches integrate link stability estimation, mobility prediction, and QoS-aware path selection to minimize delay and packet loss while ensuring efficient bandwidth utilization. Researchers are also incorporating artificial intelligence, fuzzy logic, and metaheuristic optimization techniques to dynamically choose optimal path sets based on real-time traffic density, signal strength, and road topology. These innovations collectively strengthen network resilience, ensuring seamless communication in both urban and highway vehicular environments.
