Embodiment 1

[0040] as attached figure 1 As shown, the high-performance server of the present invention is applied to the method in the vehicular self-organizing network. The method is to use the high-performance server as a roadside unit, adopt an RSU-assisted macro path selection mechanism, and deploy the vehicle node and the roadside RSU information interaction and multi-category V2R message statistics to obtain the distribution of vehicles on the road, so as to calculate the road density, in order to ensure connectivity and short path priority, and adopt a global design idea to select a route from the source node to the target node the optimal transmission path.

Embodiment 2

[0042] as attached figure 2 As shown, the high-performance server of the present invention is applied to the method in the vehicle-mounted ad hoc network, and the specific steps of the method are as follows:

[0043] S1. Using high-performance servers as RSUs, making RSUs mobile network nodes and increasing node processing capabilities;

[0044] S2. Divide each road segment into one or more connected graph areas; wherein, the size and division method of the connected graph area are determined by referring to the length of the road, the transmission range of the vehicle and the RSU.

[0045] S3. Configure a high-performance server for data model calculation and transmission in each connectivity graph area as a roadside unit or a mobile roadside unit;

[0046] S4. In the transportation network, the vehicle node knows the area number of the connected graph to which it belongs and the coordinate position of each RSU at any time through GPS or electronic map equipment, and at the...

Embodiment 3

[0055] The verification is carried out on a small server, the network simulator NS-3 is used to build a model on the server for simulation, and the VANET simulation mobile model simulation software Bonnmotion with high application frequency is used to generate the required simulation scene files. Bonnmotion software is developed by the communication research group of University of Bonn, Germany. It is a scene creation and scene analysis software based on Java. It has a wide range of applications in Ad Hoc network and VANET network simulation. Use Bonnmotion software to generate the Manhattan needed for simulation. mobile model, as attached Figure 4 shown; then convert the generated movement model into a movement tracking file (Movement file) and import it into NS-3; the parameter settings for implementing process simulation are shown in the table below:

Abstract

The invention discloses a method for applying a high-performance server to a vehicle-mounted self-organizing network, and belongs to the field of server application and Internet of Vehicles. The technical problem to be solved by the invention is how to use a server as an RSU infrastructure. The flexibility of the RSU node in the VANET is improved, and cost is reduced. Therefore, more RSUs are arranged to ensure the connectivity of the data and the selectivity of optimal calculation. The adopted technical scheme is as follows: according to the method, a high-performance server is used as a roadside unit, and a macroscopic path selection mechanism based on roadside unit assistance is adopted. The distribution condition of vehicles on a road is obtained through information interaction betweenvehicle nodes and roadside units deployed on the roadside and multi-class V2R message statistics. Therefore, the road density is calculated, and an optimal transmission path from the source node to the target node is selected by adopting a global design idea based on the principle of ensuring connectivity and short path priority.

Description

technical field [0001] The invention relates to the field of server application and vehicle networking, in particular to a method for applying a high-performance server to a vehicle ad hoc network. Background technique [0002] In recent years, the Internet of Vehicles, unmanned driving and even military vehicle-mounted driving assistance have developed rapidly. In some mobile environments and special scenarios, traditional centralized control and cellular networks with pre-installed base stations mainly use base stations for data processing, algorithm design and calculation, which can no longer meet the scenarios of self-created and self-organized Ad Hoc networks application. In order to reduce the dependence on the base station and the pressure on the data center, mobile small data processing nodes began to be used. In order to reduce the dependence on the base station and the pressure on the data center, mobile small data processing nodes began to be used. Ad Hoc netwo...
