Map-assisted Internet of Vehicles anti-interference communication method based on reinforcement learning

Abstract

The invention discloses a map-assisted Internet of Vehicles anti-interference communication method based on reinforcement learning, and belongs to the field of wireless communication, Internet of Vehicles and information security. The problem of high-reliability and safe communication of vehicle-mounted wireless equipment in an intelligent jammer attack environment is solved, information such as the current position and the vehicle density of a vehicle and the position and the size of a shielding object is obtained through a map, and the channel state between the vehicle and a receiving vehicle is estimated; receiving signal power and bit error rates of first M data packets are obtained from feedback information of a received vehicle, transmission power and channel selection of Internet of Vehicles wireless communication equipment are dynamically performed by adopting a reinforcement learning algorithm, wireless interference attacks are defended, and an attack model of a jammer does not need to be known. The message transmission reliability of the vehicle-mounted wireless communication equipment in a high dynamic environment is effectively improved, and the communication energy consumption of the wireless equipment is reduced.

Description

technical field [0001] The invention belongs to the fields of wireless communication, vehicle networking and information security, in particular to a map-assisted vehicle networking anti-jamming communication method based on reinforcement learning. Background technique [0002] The communication equipment of the Internet of Vehicles moves fast, the network topology is changeable, and applications such as traffic safety put forward higher requirements on the transmission delay and anti-interference ability, but the electromagnetic signals of the jammer and surrounding wireless transmitters may block the vehicle communication equipment. Wireless communication with passenger mobile devices reduces the quality of service for communication users, increases device communication energy consumption, and even leads to serious traffic safety accidents. Therefore, the anti-jamming communication method of the Internet of Vehicles is of great significance to ensure efficient and reliable...
