Problems solved by technology

However, when there are a large number of nodes in the network, flooding forwards broadcast packets without restriction, which will bring very high broadcast redundancy overhead to the network and cause serious channel competition, thus increasing the data transmission delay , network throughput drops severely

Abstract

The invention relates to an Internet of Vehicles relay node selection method based on fuzzy logic, and belongs to the field of information communication in a Vehicular Ad-hoc Network (VANET). An emergency safety message in the vehicle-mounted ad hoc network is transmitted between vehicles by means of a broadcast technology, wherein the key point is selection of a relay node. The core idea of the method is to comprehensively consider the coverage area, the channel busy / idle ratio and the moving factor of the vehicle based on the fuzzy logic; the forwarding priority of the vehicle serving as therelay node is obtained by establishing an appropriate fuzzy reasoning rule, and the vehicle takes the neighbor vehicle node with the maximum forwarding priority as the relay node of the next hop, sothat the number of the relay nodes is effectively reduced. The invention aims to solve the problems of broadcast message delay and redundancy caused by participation of a plurality of vehicle nodes inmessage broadcast.

Description

technical field [0001] The invention belongs to the field of information communication and relates to a fuzzy logic-based method for selecting a relay node of the Internet of Vehicles. Background technique [0002] Due to the high-speed mobility of the vehicle and the uncertainty of the driving direction, sudden traffic accidents are more prone to occur, so a lot of manpower and material resources are required to coordinate to ensure traffic safety. At present, most road accidents are handled only by accident warning signs, or by the traffic police on the spot, which is likely to cause large-scale and long-term traffic congestion, and follow-up vehicles continue to drive into the accident road in the event of unknown accidents ahead. , resulting in more serious congestion, so the fast and reliable transmission of emergency messages caused by traffic accidents is an important research topic to solve road congestion. [0003] In terms of road traffic safety and intelligent tr...
