Embodiment Construction

[0054] The technical scheme of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0055] Those skilled in the art can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meanings as commonly understood by those of ordinary skill in the art to which the present invention belongs. It should also be understood that terms such as those defined in general dictionaries should be understood as having meanings consistent with the meanings in the context of the prior art, and unless defined as here, they will not be used in ideal or overly formal meanings. Explanation.

[0056] The present invention proposes a new cluster-based highway information service system, which combines vehicle driving characteristics to select self-organizing cluster heads according to vehicle location, speed and driver behavior, making it more suitable for vehicle self-organizin...

Abstract

The invention discloses a cluster-based road vehicle-mounted ad hoc network data service communication system comprising a vehicle node, a roadside unit (RSU) and a database server, wherein a clusterhead node in the vehicle node integrates traffic / environmental information data and service demand information sent by other members in the cluster and uploads the same to the roadside unit (RSU) andtransmits the data received by the roadside unit (RSU) to the other member vehicles in the cluster; the invention further discloses a communication method of the system. In combination with the characteristics of the Internet of Vehicles, the vehicle travelling speed, the vehicle speed, the connectivity, driver behaviors are considered in the cluster head selection indicators. The most communication processes are converted from the communication of more power-hungry vehicle and the roadside unit into communication among vehicles, thereby effectively extending the endurance time of the vehicle-mounted battery, relieving the conflict and delay of data communication in the network, and providing real-time traffic and environmental information to assist drivers in route planning, and reducingcongestion and traffic accidents.

Description

Technical field [0001] The invention relates to a cluster-based highway information service system, which belongs to the technical field of vehicle-mounted self-organizing networks. Background technique [0002] With the substantial increase in the number of vehicles and the development of more complex road networks, traffic congestion, traffic accidents and greater energy consumption have increasingly become challenges affecting the development of intelligent transportation systems (ITS) including electric vehicles. Since the driver cannot obtain the relevant traffic conditions in the remote area in time, it is easy to cause traffic jams and affect travel efficiency. The effective transmission of road traffic and environment-related information (vehicle speed, density, weather, road conditions, etc.) between vehicles can help drivers plan travel routes and plans to improve road safety and traffic efficiency. Vehicles on the road can also collect local relevant data through on-b...
