Internet of vehicles routing addressing method combining geographic position and IP address

Abstract

The invention provides an internet of vehicles routing addressing method combining a geographic position and an IP address. The internet of vehicles routing addressing method combining the geographic position and the IP address comprises the following steps: a RSU receives a first request data packet sent by an OBU; the RSU stores a corresponding relation of the first interface information and the first position information; the RSU acquires the first data part; the RSU sends the first data part to a server; the RSU receives a second data packet sent by the OBU; the RSU updates the first position information of the OBU; the RSU receives a first response data packet sent by the server; the RSU acquires the interface information in the IP address of the OBU; the RSU acquires the corresponding first position information; the RSU determines the next-hop OUB; and the RSU sends the first response data packet to the next-hop OBU. By combining the geographic position and the IP address, the most suitable routing path can be selected according to the geographic positions of the opposite sides when the data packet is transmitted between the OBU and the RSU.

Description

technical field [0001] The present invention relates to vehicle-road coordination technology, in particular to a vehicle network routing addressing method combining geographic location and Internet Protocol (Internet Protocol, hereinafter referred to as IP) address. Background technique [0002] Vehicle-road collaboration technology is an important part of the intelligent transportation field. It is a communication technology that effectively integrates the Internet of Things, cloud computing, mobile Internet and data communication transmission technologies, and applies them to real-time data transmission between vehicles and servers. With the help of various technical means, vehicle-road collaboration can build a bridge for information interaction between vehicles and the outside world, improving the real-time and high efficiency of traffic information interaction. [0003] In the existing vehicle cloud client server communication system, in order to transmit information be...
