Embodiment Construction

[0019] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the present invention provides a method for modeling vehicle communication based on network connectivity, the method includes the following steps:

[0021] Step 1: According to the traffic flow theory, select the appropriate road environment;

[0022] Step 2: Suppose the vehicle speed is v i When a vehicle enters the lane, the obedience parameter is λ i Poisson distribution of ;

[0023] Step 3: Calculate the velocity as v i The distance between the two cars X i , and find the distance X between the vehicles i and time-to-head distance ΔT i The relationship between;

[0024] Step 4: Find the ΔT that obeys the Erlang distribution i The probability distribution function of ;

[0025] Step 5: According to X i with ΔT i The relationship between X i The probability distribution function of ;

[0026] Step 6: According to the...

Abstract

The invention discloses a vehicle communication modeling method based on network connectivity. The method can reasonably select the road environment. Starting from the time distance between vehicles, it is assumed that the time distance between vehicles obeys the Erlang distribution and the speed obeys the normal distribution. On this basis The obtained network connectivity can more accurately reflect the relationship between the number of vehicles arriving per unit time and the average vehicle density, and provides a good network connectivity model for the subsequent study of data transmission between vehicles.

Description

technical field [0001] The invention relates to a vehicle communication modeling method based on network connection, and belongs to the technical field of communication. Background technique [0002] In today's society, cars are an indispensable means of transportation. With the rapid economic development of countries all over the world, the number of car ownership continues to increase. Although it greatly facilitates people's daily travel and life, it also brings two most concerned issues: traffic safety and transportation efficiency. The frequent occurrence of traffic accidents has seriously threatened the personal safety of the public. The congestion suffered by most cities around the world has brought social and economic burdens, and these problems urgently need to be solved. Intelligent transportation system (intelligent information system, ITS) came into being under this background. With the development of Ad hoc network and ITS, Vehicular Ad Hoc Network (VANET) al...
