Abstract

The invention discloses a vehicle big data edge calculation unloading method based on plane separation. The method comprises the following steps: exchanging and sharing control data of the state of each edge access point by utilizing a D2D link between edge nodes so as to estimate the delay of each task in each edge access point processing queue, and judging whether the edge nodes unload the datato the edge access points or not; taking control plane data of waiting time in each edge access point as input of a data plane, maximizing long-term effectiveness of a control strategy of each edge node device by using double-depth Q learning, and iteratively selecting a random Internet-of-Vehicles device group by alliance learning so as to estimate an optimal unloading execution part; and performing data calculation and communication return according to the optimal unloading execution part, the selected edge node and the edge access point. According to the method, the control plane and the data plane are separated, and the calculation task is partially unloaded to the two planes for calculation execution, so that the execution time advantage is reduced.

Description

technical field [0001] The invention relates to a method for offloading edge computing of vehicle big data based on plane separation, and belongs to the technical field of communication technology. Background technique [0002] With the rapid development of intelligent transportation, higher requirements are put forward for the real-time communication. Relying on remote clouds to upload data and run complex algorithms results in high communication and computation delays due to the massive computational and communication loads generated by vehicles and roadside sensors. By using an edge computing architecture with certain computing power and supplemented by a remote cloud to perform edge processing on the data in intelligent transportation, the problem of excessive delay can be potentially improved and the dependence on the remote cloud can be reduced to a certain extent. [0003] Mobile edge computing (MEC) refers to moving the computing and storage capabilities of the clou...
