AI Technical Summary
In the narrowband Internet of Things (IoT) environment, existing traffic information dissemination methods cannot effectively achieve real-time dissemination of high-risk traffic information, and lack a mechanism to complete traffic status for missing, delayed, and low-quality observations, resulting in excessive consumption of communication resources and insufficient information transmission priority.
By constructing a BML matrix and introducing an improved BML narrowband traffic status release model, and utilizing narrowband observation completion mechanism, event disturbance embedding, and risk propagation correction, differential frames are generated and released according to risk priority, thereby achieving real-time modeling and priority release of traffic status.
It improves the adaptability and reliability of real-time traffic information dissemination in narrowband IoT environments, reduces communication burden, ensures timely dissemination of high-risk information, and optimizes communication efficiency through a closed-loop update mechanism.
