Dynamic silence monitoring mixing area method based on traffic light state

Abstract

The invention discloses a dynamic silence monitoring mixing area method based on a traffic light state. At present, many academic strategies put forward a method of using pseudonyms to protect track privacy in the vehicle driving process, but anonymity high efficiency, driving safety, implementation convenience and resource utilization in the put forward method cannot be considered at the same time. The method comprises three parts: a silence mixing area model based on traffic light state change, prediction of adjustment and optimization based on traffic flow change selection, and automatic adjustment of dynamic silence length based on the two models. By means of the dynamic silence monitoring mixing area method based on the traffic light state, privacy and silence driving safety can be simply and efficiently guaranteed in the urban environment, and the performance and resource utilization of the whole Internet of Vehicles safety application are remarkably improved.

Description

technical field [0001] The invention belongs to the field of vehicle pseudonym replacement in a vehicle network, and relates to a novel dynamic mixing area design method allowing pseudonym replacement. Background technique [0002] In recent years, vehicle-mounted ad hoc network (VANET) has provided great help to the intelligent development of the Internet of Vehicles with its dynamic and efficient topology. It builds a network by using each vehicle as a communication node, allowing vehicles to communicate with all surrounding environments. Communication (V2X), its goal is to provide and construct a non-center dynamic self-organizing real-time topology network during driving on the road, so as to mainly realize some safety applications such as cooperative driving, accident warning and non-safety applications such as infotainment. This safety application technology improves vehicle driving safety and traffic efficiency by providing continuous dynamic communication between the...
