Abstract

The invention provides a vehicle-connected multi-agent wireless dynamic networking for automatic driving and an operation method of the vehicle-connected multi-agent wireless dynamic networking. According to the invention, networking is carried out on the intelligent vehicles through the ZigBee wireless module, and position information and speed information of adjacent nodes of the vehicle-connected multi-agent are transmitted to the ZigBee terminal node through the ZigBee routing node or the ZigBee coordinator node, so that information interaction of positions and speeds of the intelligent vehicles is realized, and the purpose of multi-agent consistency control is achieved. Aiming at the characteristics of uncertainty of a vehicle-connected multi-agent system, instability of a network transmission environment and mobility of network nodes, the invention provides a vehicle-connected multi-agent dynamic network topology structure design method based on super nodes, and the method comprises design of an in-vehicle wireless networking module of an intelligent vehicle, design of an out-vehicle wireless networking module, and design of a vehicle-connected multi-agent network topology. According to the invention, the problem of wiring complexity caused by wired connection can be effectively reduced, and the influence of environment uncertain factors on wireless networking communication among the vehicle-connected multi-agent can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to an automatic driving-oriented multi-agent wireless dynamic networking and an operation method thereof. Background technique [0002] In recent years, the advancement of science and technology has greatly promoted the development of intelligent transportation, and the technology of CAV (connected and autonomous vehicle) has emerged as the times require. CAV technology can be decomposed into vehicle interconnection technology and automatic driving technology. Vehicle interconnection technology mainly includes two types of communication links, namely vehicle-to-vehicle (V2V, vehicle to vehicle) communication and vehicle-to-roadside base station (V2I, vehicle to infrastructure) communication. V2V communication allows in-vehicle users to communicate over short and medium distances, provides low-cost deployment, and supports short messaging with low latency. V2I communicatio...
