Forwarding method and device based on predicted content position and flow, equipment and medium

The invention discloses a forwarding method, device and equipment based on predicted content position and flow, and a medium, and the method comprises the steps that a key node obtains an interest packet based on a vehicle ad hoc network and a named data network; viewing content source information in the content position table according to the content name in the interest packet; the content position table is a table which is maintained by a key node of a road intersection and is used for recording content source information; correcting the vehicle position of the content position table according to the content source information; estimating a network state from the key node to the data source according to the corrected vehicle position; according to the network state, selecting a forwarding direction to maximize the success rate and minimize the time delay as an optimization target, solving the optimal target by using an improved deep Q network algorithm, selecting an optimal forwarding direction and determi
