V2X Message Filtering via Priority Queues for Computational Efficiency

The patent segments the stream of BSMs into multiple queues based on priority levels. High-priority BSMs (from nearby vehicles or those indicating potential threats) are placed in high-priority queues for immediate processing, while low-priority BSMs (from distant vehicles or benign situations) are placed in low-priority queues for deferred or reduced-rate processing. This segmentation allows the system to maintain high detection reliability for critical threats while managing computational resources efficiently through differentiated processing rates across queue segments.

The patent implements dynamic processing rates for different BSM queues. High-priority queues receive immediate full-detail processing with high accuracy, while low-priority queues are processed at reduced rates or with simplified processing. The system dynamically adjusts the level of processing detail based on the priority classification of each BSM stream, ensuring that critical threats receive accurate real-time analysis while non-critical messages are processed with less computational overhead, thus meeting real-time requirements for safety-critical operations.

The patent applies partial processing action by selectively processing only the most critical BSMs at full detail while using reduced-rate or simplified processing for less critical messages. Instead of allocating computational resources to process every BSM at maximum capability, the system performs sufficient processing on high-priority messages to ensure safety, and accepts reduced processing for low-priority messages where full accuracy is less critical. This approach achieves adequate overall processing capability without requiring expensive high-power hardware that would be needed to process all messages at full detail.
