Embodiment 1

[0032] A method for setting the probability of sending a car message in a car social network, such as figure 1 shown, including:

[0033] The message sending probability of each car in the target vehicle social network is set as the same function expression about the degree value of the car;

[0034] Calculate and compare the average PNAoI of the target vehicle social network under different parameters in the function expression based on the distribution of vehicle degree values ​​and network parameters in the vehicle social network, as well as the search step size and search upper and lower bounds of each parameter in the function expression, Obtain each parameter value in the function expression corresponding to the minimum average PNAoI and the message sending probability of each automobile;

[0035] Among them, the average PNAoI represents the average value of a series of maximum values ​​of NAoI evolved over time, and NAoI represents the maximum value of AoI correspondin...

Embodiment 2

[0121]A computer-readable storage medium, the computer-readable storage medium includes a stored computer program, wherein, when the computer program is run by a processor, the device where the storage medium is located is controlled to execute the above-mentioned vehicle social network A method for setting the probability of sending a vehicle message in a vehicle.

[0122] The relevant technical solutions are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention belongs to the technical field of wireless communication, and particularly discloses a method for setting the automobile message sending probability in a vehicle-mounted social network.The method comprises the following steps: setting the message sending probability of each automobile in a target vehicle-mounted social network as the same increment function expression about an automobile degree value; and calculating and comparing average PNAoI of the target vehicle-mounted social network under parameters in different function expressions based on vehicle degree value distribution and network parameters in the vehicle-mounted social network and the search step length and search upper and lower bound values of each parameter in the function expressions to obtain each parameter value in the function expression corresponding to the minimum average PNAoI and the message sending probability of each automobile. In the future-oriented vehicle-mounted social network, the influence of the social relationship between the vehicles on the communication performance of the vehicle-mounted social network is fully considered, so that the average PNAoI of the vehicle-mounted social network can be effectively reduced, and the freshness of the information received by the vehicles is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and more specifically relates to a method for setting the probability of sending a car message in a car social network. Background technique [0002] In the Internet of Vehicles for future self-driving cars, human intervention in car driving will be greatly reduced, so more time can be allocated to do things other than driving during car driving. It is foreseeable that with the continuous improvement of the communication functions of automobiles, automobiles will become the main carrier for people to communicate and socialize, just like smartphones. In this context, in-vehicle social network has become a research hotspot in the next generation of in-vehicle network. In addition, human beings are the main users of cars in the in-vehicle social network, so the information disseminated in the in-vehicle social network is usually related to human travel, such as road congestion, parki...
