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:
[0056] Simulation parameters parameter settings Simulation Platform and Tools Ubuntu12.04+NS-3.23+Bonnm...
