摘要: The invention discloses a vehicle network message optimization broadcast method based on dynamic priority. comprises the following steps: monitoring status in real time; calculating priority and effective distance of to be sent an application layer according type surrounding environment data stored terminal at acurrent moment case emergency; updating current multicast broadcast; acquiring access category index optimized frame; finally, performing channel competition sending by inserting into queue through MAC (Media Access Control) layer. Through adoption method, corresponding quality service can provided for messages different priorities, with higher emergency degrees have toenjoy resources.
