Embodiment 1

[0042] In accordance with the above technical solution, this embodiment provides a traffic-aware routing method applied to the Internet of Vehicles, in which data packets are forwarded from the starting node to the destination node sequentially through multiple unit head vehicles;

[0043] Assume that the road section connecting any two adjacent intersections is divided into multiple road section units, each road section unit includes multiple nodes, and the head vehicle is the node closest to the unit center in each road section unit;

[0044] The forwarding of the data packet includes the forwarding of the data packet at the intersection and the forwarding of the data packet in the straight section;

[0045] The data packet is forwarded through the nodes in each road unit in the road section, and the node forwarding the data packet in each road section unit is the head vehicle of the unit, and the forwarding distance of each data packet between nodes is less than or equal to ...

Abstract

The invention provides a traffic-aware routing method applied to Internet of Vehicles. A data packet is transmitted from a starting point to a destination point through forwarding between nodes, wherein the forwarding of the data packet comprises data packet forwarding at an intersection and data packet forwarding in a straight road section, and an intersection road section needs to be selected according to road condition information of each road section which is broadcast by a data collection package at the intersection when the forwarding is carried out at the intersection. According to themethod, the problems of unstable link and large transmission delay are avoided, and the local optimum problem in the geographic routing is solved.

Description

technical field [0001] The invention belongs to the communication field of the Internet of Vehicles, and in particular relates to a traffic perception routing method applied to the Internet of Vehicles. Background technique [0002] At present, how to design a routing protocol with excellent performance in the Internet of Vehicles has become a hot research topic in the field of Internet of Vehicles and smart cars. In the Vehicular Ad hoc Network (Vehicle Ad hoc [0003] In VANETs), each vehicle with wireless communication performance is a mobile node, and these nodes cooperate with roadside base stations to realize real-time collection and sharing of traffic information. Numerous VANETs routing protocols are transitioned from the protocols of Mobile Ad-hoc Network (MANET), but these routing methods do not consider some special characteristics of vehicular networks which are different from ad hoc networks. [0004] To enable communication between spatially separated vehicle...
