Embodiment 1

[0046] refer to figure 1 As shown, this embodiment provides an adaptive V2I access scheme to ensure the age fairness of vehicle information in the vehicle network, and the steps are as follows:

[0047] Step S1: first discretize the time interval of the network, and observe the vehicle situation in the network in each discrete time interval n=1, 2, . . . , t. The duration of each time interval is T; then, according to the definition of information age, the calculation method for the information age of equipment (smart sensor nodes and vehicles) in a discrete time observation interval is established, then the information age can be expressed as follows:

[0048]

[0049] in is the information age of device i in time slot t; is the moment when the device i data packet is generated for the current moment t; can be expressed as where N v is the number of vehicles in the network in the current discrete time observation interval; 0 means the smart sensor node, 1,...,N v...

Embodiment 2

[0097] Based on the same inventive concept, this embodiment provides a V2I access system that ensures the age fairness of vehicle information in the Internet of Vehicles. The problem-solving principle is similar to the xx method described above, and the repetition will not be repeated.

[0098] This embodiment provides a V2I access system that ensures age fairness of vehicle information in the Internet of Vehicles, including:

[0099] The average information age acquisition module is used to discretize the time interval of the vehicle network, and obtain the average information age of devices including smart sensor nodes and vehicles at each discrete time interval;

[0100] The age fair benefit acquisition module is used to obtain the average information age of the smart sensor node and the sum of the average information age of the vehicle according to the average information age of the device, and obtain each discrete The age-fairness loss of the vehicular network at time int...

Abstract

The invention discloses a V2I access method and system for ensuring age fairness of vehicle information in the Internet of Vehicles. The method comprises the following steps: obtaining the average information age of equipment including intelligent sensor nodes and vehicles at each discrete time interval, obtaining the age fairness loss of a vehicle-mounted network at each discrete time interval, and obtaining the age fairness benefit of each discrete time interval according to the age fairness loss; obtaining the state of the intelligent sensor node according to the average information age of the intelligent sensor node, the average information age sum of the vehicles, the minimum contention window of the intelligent sensor node and the number of devices in the vehicle-mounted network; and taking the state, the action and the immediate income as parameter input of a neural network of a Rainbow DQN algorithm, and finally training intelligent sensor nodes according to the Rainbow DQN algorithm. According to the invention, the problem of unfair vehicle information age caused by common communication between different sensor nodes and the vehicle in a highway scene covered by a base station is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle task offloading, in particular to a V2I access method and system for ensuring age fairness of vehicle information in the Internet of Vehicles. Background technique [0002] With the development of the economy and the improvement of the quality of life, people's urgent demand for a comfortable driving experience is increasing day by day. Therefore, the increasingly common communication network and vehicle-mounted equipment have produced a large number of applications to meet the user's road driving needs. Making vehicle networking an integral part of road driving. The Internet of Vehicles is an automotive communication system that includes other types of communication, such as V2I (Vehicle-to-1 infrastructure). On the one hand, in order to ensure the normal use of these applications, this requires vehicles to communicate with base stations or roadside infrastructure. Perform frequent data exchange...
