Reliable Vehicle Platooning via Redundant 5G Link Aggregation in Smart Roads

Vehicle platooning has gained attention due to its potential to improve traffic flow and reduce congestion. However, ensuring reliable communication among vehicles in a platoon presents significant challenges, particularly in dynamic environments where connectivity is essential. This study introduces a framework that leverages redundant 5G link aggregation to enhance communication reliability in smart roads. Our approach integrates multiple 5G connections, allowing the system to maintain continuous data exchange even if a link fails. Through a multi-layered communication strategy, the framework dynamically chooses the optimal link based on real-time network conditions. The results from extensive simulations reveal that this method considerably boosts robustness against communication outages and reduces latency, leading to improved performance metrics for vehicle platooning. This work represents a crucial advancement toward achieving reliable autonomous vehicle coordination, ultimately contributing to the development of safer and more efficient transportation networks.
