Brief introduction of project results

The invention discloses a real-time road section scoring method for content routing of vehicle-mounted AD hoc network. In order to obtain the topology of Road vehicles accurately, the road section is divided into three parts, and the Road side unit (RSU) is relied on to perceive the road traffic information in real time. RSU evaluates the connectivity of the three parts of the road section respectively according to the perceived road traffic information, and obtains the overall connectivity rate of the road section from the connectivity of the three parts of the road section. Combined with road length and average road speed, the road section is scored in real time. This method can reflect the real situation of the road and provide a good support for the message routing path planning of Vehicular AdHoc Network (VANET) in an urban environment, especially the VANET routing algorithm based on road segment scoring, so as to ensure the overall optimality of the VANET routing algorithm.

Performance indicators

We propose a real-time road segment scoring method, which defines the interface between the perception layer and the data evaluation layer, and on this basis gives the connectivity characteristics between vehicles on various modern urban roads. This method models the connectivity of vehicles on various urban roads, and gives its direct and inter-connectivity assessment. It provides a good support for the message routing path planning of vehicle-mounted AD hoc networks in urban environment. The typical routing and forwarding protocol in VANET environment is tested. The test results show that the success rate of data forwarding reaches 98% and the average forwarding delay reaches ms level, which can meet the QoE standard of users' audio and video access.

Scope of application and market prospects

This project belongs to the field of Vehicular Ad-Hoc Network, and it is a comprehensive road segment scoring method, which is suitable for urban Vehicular ad-hoc network (VANET) environment, especially for content routing planning.
