Problems solved by technology

Among them, the SAR (Security-Aware ad hoc routing protocol) protocol is a representative network security routing protocol under mobile Ad hoc. However, this method also fails to fully consider the dynamic characteristics of the network in the Internet of Vehicles environment, and the trust value of nodes Solidified, does not conform to the actual application of the actual Internet of Vehicles, and there is also the problem of routing establishment failure

Embodiment Construction

[0023] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The invention provides a data transmission method under the Internet of Vehicles, and its specific implementation process is as follows:

[0025] Step 1, establish the reputation evaluation module of the Internet of Vehicles; including the reputation update module in the design route establishment stage and the reputation update module in the data transmission stage.

[0026] The specific process of designing the reputation update module in the route establishment phase is: when a node tries to return to RREP, that is, when it is ready to establish a reverse route, verify whether the information in the routing table contained in the current node is equal to the purpose of the destination node description information in RREQ , if the verification results are not equal, quickly reduce the reputation value of the d...

Abstract

The invention discloses a reliable data transmission method under the Internet of Vehicles, which includes establishing dynamically updateable reputation values ​​of nodes in the Internet of Vehicles, thereby obtaining a reputation evaluation module of the Internet of Vehicles; monitoring the nodes in the Internet of Vehicles, and establishing the Internet of Vehicles Credibility evaluation module of the credibility evaluation module; based on the evaluation results of the reputation evaluation module, routes are established, and multiple routes are screened to obtain safe and reliable routes; then the data transmission process is established, and the data transmission process is checked in real time to complete the data transmission . In the process of route establishment and data transmission, the node reputation is checked and updated in time, and the node's identity credibility is evaluated by the node's behavior credibility to ensure the reliability and stability of data transmission.

Description

technical field [0001] The invention belongs to the field of urban intelligence technology; in particular, it relates to a data transmission method under the Internet of Vehicles; in particular, it is a trusted data transmission method based on the AODV communication protocol under the Internet of Vehicles environment. Background technique [0002] With the rapid development of Internet of Things technology in the field of transportation, the Internet of Vehicles, as a key technology of urban intelligent transportation, has also made great progress. Since the Internet of Vehicles itself has the characteristics of dynamic network topology and short vehicle interaction time, communication protocols such as AODV (Ad hoc On-demand Distance Vector Routing) commonly used in the current Internet of Vehicles environment face huge challenges in terms of safety and reliability. Among them, the SAR (Security-Aware ad hoc routing protocol) protocol is a representative network security r...
