Embodiment 1

[0025] See attached Figure 1-3 , a method for dynamic ad hoc networking of the Internet of Vehicles, characterized in that: comprising the following steps:

[0026] S1. The own vehicle (HV) receives the communication message from the nearby connected vehicle (RV);

[0027] S2. Determine whether the connected vehicle (RV) is in the management queue. If the connected vehicle (RV) is in the management queue, continue to calculate the own vehicle (HV) trajectory. If the connected vehicle (RV) is not in the management queue, then judge the connection Whether the vehicle (RV) meets the head direction condition, if the connected vehicle (RV) meets the head direction condition, add the vehicle to the node management queue, and then calculate the own vehicle (HV) trajectory;

[0028] S3. After completing the calculation of the trajectory of the own vehicle (HV), continue to calculate the trajectory of the connected vehicle (RV);

[0029] S4. If the trajectory point data of the traje...

Embodiment 2

[0031] This embodiment is similar to Embodiment 1. Further, the method for judging whether the head direction condition is satisfied is as follows: take the own vehicle (HV) as the center, and filter out the vehicles whose head direction points to the center according to the head direction information of the connected vehicle (RV), Added to the node management queue and with velocity direction model P i (v, h) represents, where i represents the serial number of the connected node, V represents the speed of the connected vehicle, and h represents the head direction of the connected vehicle. Such as figure 1 As shown, the vehicles that meet the networking conditions are RV1, RV2, RV3, and RV4.

[0032] The method of calculating the trajectory of the vehicle is to calculate the trajectory points of the vehicle (HV) based on the position information, speed, direction of the vehicle head and body information of the vehicle (HV), and use the time position model MH j (t, x, y) is s...

Abstract

The invention provides a dynamic self-networking method of the Internet of Vehicles. The method comprises the following steps: S1, receiving, by a present vehicle, a communication message of a nearbyconnected vehicle; S2, judging whether the connected vehicle is in a management queue, if the connected vehicle is in the management queue, continuing to calculate a movement trajectory of the presentvehicle, if the connected vehicle is not in the management queue, judging whether the connected vehicle satisfies a headstock direction condition, if the connected vehicle satisfies the headstock direction condition, adding the vehicle to a node management queue, and then calculating the movement trajectory of the present vehicle; S3, after the movement trajectory of the present vehicle is calculated, continuing to calculate the movement trajectory of the connected vehicle; and S4, if the trajectory point data of the movement trajectory of the present vehicle and the movement trajectory of the connected vehicle have the same point, identifying an application scene and alarming; and if the track point data are completely different, deleting the node.

Description

technical field [0001] The present application relates to a method for an ad hoc network of the Internet of Vehicles, in particular, a method for a dynamic ad hoc network of the Internet of Vehicles. Background technique [0002] The communication technology C-V2X based on the cellular network is the development trend of the Internet of Vehicles in the future. It has the advantages of low deployment cost and wide network coverage. As an important part of 5G, C-V2X continues to evolve. In the Internet of Vehicles, the networking strategy is a key technology, and it is also the focus and difficulty of research. In the wide-area network, the research on the networking strategy of the Internet of Vehicles needs to solve the following problems: 1. The number of connected nodes is huge, and the application environment is complex and changeable; 2. The density of communication nodes is high, and there is a problem of communication channel competition; 3. Vehicle terminals It is a...
