Hyper-Accurate Cooperative Perception Routing for Millimeter Wave V2X Communications in Dense Urban Environments

**Abstract:** This paper introduces a novel cooperative perception routing (CPR) framework optimized for millimeter wave (mmWave) Vehicle-to-Everything (V2X) communications within dense urban environments. Addressing the limitations of traditional routing protocols in rapidly changing urban landscapes and the inherent path loss challenges of mmWave frequencies, our system leverages a hierarchical prediction network and dynamic beam steering optimization to ensure ultra-reliable low-latency communication (URLLC) for critical safety applications. The proposed CPR mechanism enhances signal reliability by intelligently routing data through a network of connected vehicles and road-side units (RSUs) predicted to exhibit the most favorable communication links based on real-time environmental data and anticipated vehicle trajectories. This approach achieves a 2.5x improvement in message delivery rate compared to baseline routing protocols under complex urban conditions, while maintaining URLLC requirements for advanced driver-assistance systems (ADAS) and autonomous driving functionalities.
