Physical layer security resource allocation method in ICV network

Abstract

The invention discloses a physical layer security resource allocation method in an ICV network, solves the problem that an existing allocation mode cannot optimize V2V time delay, and belongs to the technical field of wireless communication. The method comprises the following steps: S1, a sending vehicle in each V2V link being an intelligent agent, the intelligent agent being realized by adoptinga deep reinforcement learning network and comprising a trained target network and a real-time network, and the target network being used for updating parameters of the real-time network; S2, each intelligent agent obtaining local observation of the environment, including information of legality, interference and eavesdropping channels, sending load, time delay limitation, training iteration timesof a target network and exploration utilization probability; S3, each intelligent agent outputting an action by using a real-time network according to local observation, wherein the action comprises afrequency band occupied by signal sending and transmitting power; S4, the target networks of all the intelligent agents receiving the same reward from the environment, the environment entering the global state of the next moment, executing the step S2, and the reward comprising the system secrecy capacity and the time delay limit.

Description

technical field

[0001] The invention relates to a resource allocation method based on reinforcement learning in an ICV (Intelligent Connected Vehicle, Intelligent Networked Vehicle) network, belonging to the technical field of wireless communication. Background technique

[0002] In recent years, with the rapid development of communication technology, the first phase of 5G has been frozen in 3GPP R15. Among them, the Internet of Vehicles technology including V2X (Vehicle to Everything, information exchange between the vehicle and the outside world) has become the focus of 5G research. Networking has become one of the main application scenarios of 5G. China's V2X communication technology based on LTE and 5G has become the main technology of intelligent transportation systems in recent years. V2V (Vehicle-to-Vehicle, vehicle-to-vehicle communication) technology has a wider communication range, lower latency and higher The transmission rate can adapt to various application sce...
