An application method of a wireless communication technology in Internet of Vehicles V2V

Abstract

The invention provides an application method of a wireless communication technology in Internet of Vehicles (V2V), which is characterized in that a first vehicle-mounted gateway is connected with a wireless Mesh network, and the method comprises the following steps that S1, when a second vehicle-mounted gateway is close to the first vehicle-mounted gateway, the second vehicle-mounted gateway sendsa proximity request with identity encryption information; S2, the first vehicle-mounted gateway uploads the identity encryption information to an upper-layer server; S3, the upper-layer server judgeswhether the identity encryption information is legal or not, if yes, a legal and safe communication link is established between the first vehicle-mounted gateway and the second vehicle-mounted gateway, and meanwhile, the second vehicle-mounted gateway joins the wireless Mesh network; S4, when the second vehicle-mounted gateway is far away from the first vehicle-mounted gateway, periodically the air interface signal is monitored and the current signal quality of the second vehicle-mounted gateway is judged; S5, the second vehicle-mounted gateway exits from the wireless Mesh network according to the signal quality or establishes a communication link with the current adjacent third vehicle-mounted gateway. The method has the advantages of high speed, stability, cooperation between vehicles and vehicles and a cooperative ad hoc network mode.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and in particular relates to an application method of wireless communication technology in the V2V Internet of Vehicles. Background technique [0002] In the existing technology, RFID or Ad Hoc technology is generally used for vehicle networking. The performance and scalability of RFID technology or Bluetooth are very limited, and it cannot meet the bandwidth requirements of various sensors and image transmission in V2V communication. AdHoc technology does not support For traditional IP, a dedicated and efficient wireless multi-hop routing protocol must be designed, which has limitations in the dynamic changes of network topology. [0003] Therefore, there is a need for a wireless communication technology with a reasonable scheme, high speed, stability, mutual cooperation between vehicles and a cooperative self-organizing network in the V2V application method of the Internet of V...
