Communication connectivity analysis method for bus dynamic scheduling under internet of vehicles environment

Abstract

The invention discloses a communication connectivity analysis method for bus dynamic scheduling under an internet of vehicles environment, and the method is a method for analyzing the intra-area wireless communication connectivity under the situation of bus dynamic scheduling of a vehicle ad hoc networks (VANET). The method comprises steps of firstly determining elements participating in the bus dynamic scheduling under the internet of vehicles environment; determining a communication method adopted among the elements of the bus dynamic scheduling; classifying a communication structure in the bus dynamic scheduling process into a route-vehicle communication system and a vehicle-vehicle communication system so as to analyze the basic structural characteristics of the communication connectivity in the scheduling process; and finally under the limitation of relevant proposal condition, calculating a wireless communication connectivity probability of the bus dynamic scheduling within a given regional range to obtain the connectivity of the intra-area wireless communication.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a communication connectivity analysis method for dynamic bus scheduling in a vehicle networking environment. Background technique [0002] The dynamic bus scheduling in the Internet of Vehicles environment is an automatic scheduling technology based on new communication means, multi-source information acquisition and new scheduling concepts. The dispatching technology uses an ad hoc network specially designed for inter-vehicle communication. It applies ad hoc network technology to inter-vehicle communication, enabling drivers to obtain other vehicles' status information (such as vehicle speed, direction, position, brake pad pressure, etc.) and real-time road conditions. [0003] In the process of bus dynamic scheduling in the Internet of Vehicles environment, when a traffic accident or traffic accident occurs, the bus information center mainly send...
