SPEED-BASED RELAY SELECTION IN VEHICLE-TO-VEHICLE (V2V): A REVIEW

Abstract

Vehicle-to-vehicle (V2V) communication holds immense potential for improving road safety and traffic efficiency by enabling information exchange between vehicles. However, reliable data transmission in dynamic traffic environments poses significant challenges. This study explores speed-based relay selection as a novel approach to enhance V2V performance. In contrast to traditional methods focusing on signal strength or distance, this approach prioritizes faster vehicles as relays, aiming to reduce latency and improve reliability. While promising, speed-based selection faces challenges like accurate speed estimation, temporal variability, and scalability. Future research directions include advanced speed estimation techniques, adaptive selection strategies, robust security and privacy mechanisms, scalable algorithms, and energy-efficient protocols. By addressing these challenges and actively pursuing further research, speed-based relay selection can revolutionize V2V communication, paving the way for a safer and more efficient future of transportation.
