Abstract

The invention discloses a method for clustering artificial fish swarms in the Internet of Vehicles, a storage medium and a device. The method uses the adaptive value F of the artificial fish swarm algorithm to perform clustering in the Internet of Vehicles. The adaptive value F is determined by the vehicle node degree C and the vehicle node Mobility CR is jointly decided. The invention analyzes the urban intersection environment of the Internet of Vehicles, designs new cluster head evaluation parameters, and proposes a vehicle clustering method based on artificial fish swarms; the method screens out suitable clusters within the network through the behavior of artificial fish. Cluster heads, so as to obtain the optimal number of vehicle clusters; the research results show that compared with the well-known CLPSO algorithm, the method proposed in the present invention can generate fewer vehicle clusters, which means that it can better reduce communication overhead and reduce end-to-end end-to-end delay.

Description

technical field [0001] The invention relates to the field of the Internet of Vehicles, in particular to a method for clustering artificial fish schools in the Internet of Vehicles, a storage medium and a device. Background technique [0002] With the development of intelligent transportation systems, Vehicle Networking (Vehicular Ad Hoc Networks, VANET) as a component of intelligent transportation systems has become a research hotspot in the field of wireless ad hoc networks in recent years. VANET is of great significance to reducing traffic accidents, alleviating road congestion, and meeting various driving needs. Although the Internet of Vehicles is a branch of the mobile ad hoc network, it has characteristics different from the mobile ad hoc network, such as strong vehicle node mobility, frequent network topology changes, intermittent communication links between nodes, regular vehicle movement trajectories, and the influence of road distribution. . The traditional AdHoc...
