State-adaptive Internet of Vehicles near field communication resource allocation method

The invention discloses a state-adaptive Internet of Vehicles near field communication resource allocation method, which comprises the following steps of: in Internet of Vehicles near field communication with high connection density, optimizing the value of a resource reservation interval parameter by a vehicle-mounted user terminal computing unit by applying a fuzzy logic system based on a communication resource load state parameter and a communication connection density state parameter; therefore, the number of available resources is dynamically adjusted. A global optimal fitness function based on a resource reservation interval parameter and a local optimal fitness function based on a sub-channel signal to interference plus noise ratio parameter are constructed, and a particle swarm optimization algorithm is applied to select available resources matched with a communication state so as to propagate near field inter-vehicle communication messages. According to the dynamic adjustment strategy of the number o
