Problems solved by technology
When malicious nodes know the rules of the game and try to maintain a certain trust value before attacking, or normal nodes suffer sudden attacks due to some reasons, relying solely on reputation values for safe relay selection cannot effectively prevent such behaviors
[0008] However, in the process of cooperative transmission, in addition to the damage of the information itself in the process of channel transmission, the failure of the cooperative transmission task may also be caused by the unsafety of the relay vehicle due to various reasons. Therefore, how to choose a safe and reliable medium It is still a difficult problem to simultaneously exclude potential malicious nodes while reducing the impact of emergencies on assisted transmission.

Embodiment Construction
[0050] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.
[0051] The relay vehicle selection method provided in this application can be applied to such as figure 1 in the application environment shown. The drive test unit 100 communicates with the target vehicle 200 through the relay vehicle 300 , and the drive test unit 100 communicates with the relay vehicle 300 and the relay vehicle 300 and the target vehicle 200 directly through the vehicle network. The drive test unit 100 obtains the responding vehicles within the communication range, performs preliminary screening according to the original reputation value of the respo...

The present application relates to a method, apparatus, computer equipment and storage medium for selecting a relay vehicle. The method includes: calculating a comprehensive risk value according to the jump value of the reputation value of each vehicle in the initial preselected relay set, the total assistance success rate, the correlation between vehicles and the influence of abnormal vehicles within a preset range; In the initial preselected relay set, the speed of each vehicle, the remaining bandwidth and the relative position with the target vehicle are calculated to calculate the assistance reliability; according to the comprehensive risk value and the assistance reliability, the preselected relay node screening is calculated. value, and filter the vehicles in the initial pre-selected relay set according to the pre-selected relay node screening value to obtain the final pre-selected relay set; match the target vehicle set with the final pre-selected relay set to obtain each a relay vehicle that matches the target vehicle. The method can ensure the safety of the selected relay vehicle.
Description
technical field [0001] The present application relates to the technical field of vehicle network, and in particular, to a method and device for selecting a relay vehicle. Background technique [0002] With the rapid development of the automotive industry Internet, vehicles can transmit information through vehicle-to-RSU (V2R) or vehicle-to-vehicle (V2V) communication. Since the information transmission in the vehicle network will be constrained by the practical use characteristics such as the rapid movement of vehicle nodes, the effective communication range of the communication entity, and the safety of the vehicle, it is often necessary to select a specific relay vehicle to cooperatively transmit information. [0003] With the continuous development of Vehicle Ad-hoc Networks (VANETs) and the continuous enhancement of in-vehicle communication, computing and storage capabilities, there are more and more choices of relay vehicles using different methods. [0004] After sear...
