Adaptive vehicle communication system based on relay transmission

Abstract

The invention provides an adaptive vehicle communication system based on relay transmission. The adaptive vehicle communication system is provided with a vehicle-mounted wireless network intelligent control module, a vehicle-mounted wireless network sensor module, a vehicle-mounted wireless network networking and transmission module, a vehicle-mounted wireless network data management module and avehicle-mounted wireless network application module, the adaptive vehicle communication system deems vehicles in a vehicle-mounted wireless network as potential relay nodes and adaptively selects a relay forwarding and relay cooperation strategy; and the adaptive vehicle communication system combines information grading with relay selection based on a relay selection algorithm of a cluster, and determines the range of the cluster and selects the relay node according to the priority of the information. The adaptive vehicle communication system can achieve a wireless ad hoc network and adaptivecooperative communication between the vehicles, ensure the communication continuity and information sharing and transmission by the relay transmission, and avoid the relay collision problem resultingfrom the fact that a plurality of vehicles select the same relay node at the same time by adoption of an information grading mode, thereby improving the communication efficiency and quality of the vehicle-mounted wireless network.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to an adaptive vehicle communication system based on relay transmission. Background technique [0002] With the development of our country's economy and the improvement of science and technology, the transportation industry has developed rapidly, and automobiles have penetrated more and more into people's daily life. The rapid increase of vehicles will inevitably lead to a series of social problems such as traffic congestion, frequent traffic accidents, and parking difficulties. At the same time, urban residents have higher requirements for services such as vehicle collision warning, traffic congestion detection, and information sharing. Therefore, the concept of intelligent transportation came into being. At present, traditional intelligent transportation systems rely heavily on pre-deployed infrastructure such as cameras at major intersections and sensors embedded i...
