Cluster Association Boundary and Inter-cluster Switching Method for Internet of Vehicles Based on Apollonius Circle

Abstract

The present invention discloses an Apollonius round-based internet of vehicle cluster association boundary and clusters switching method. The method includes a first step of collecting, by a vehicle information collecting system, driving state and traffic flow clustering information of associated vehicles and adjacent cluster head vehicles in real time; a second step of switching between clusters and modeling a cluster association boundary by using an Apollonius round according to collected latest driving state information; and a third step of according to current driving state information of vehicles, deducing a cluster association boundary modeling function by using an Apollonius round-based internet of vehicle clusters switching and cluster association boundary method, and determining whether to perform switch on the vehicle in real time, wherein if a cluster association boundary function formula holds, the vehicle is switched to a front cluster head, if the cluster association boundary function formula does not hold, the vehicle is not switched. The method has the advantages of novel principle, wide application range, and good reliability.

Description

technical field [0001] The present invention mainly relates to the communication field of the Internet of Vehicles, in particular to a cluster association boundary and inter-cluster switching method of the Internet of Vehicles based on the Apollonian circle. Background technique [0002] In recent decades, the intelligent transportation system ITS (Intelligent Transport System) has been very popular. It can be said that it is the development direction of the future transportation system, and the use of multi-source data, data fusion and other algorithms to achieve the best performance of the system is currently the A trend of ITS applied research. On urban roads, the Internet of Vehicles (IoV) is formed between vehicles, which is a very important part of intelligent transportation. The continuity of vehicle-to-vehicle communication can be completed through inter-cluster switching of the Internet of Vehicles. Due to the high-speed driving of the vehicle and the limited rang...

AI Technical Summary

Problems solved by technology

Due to the high-speed driving of the vehicle and the limited inter-vehicle communication range, it is easy to cause the interruption of the topological connection of the Internet of Vehicles

At the same time, inter-cluster switching in the Internet of Vehicles is a very complicated process. How to conveniently and intuitively describe the switching model and design a simple, efficient, and practical switching method is a problem.
