Embodiment Construction

[0073] In order to describe the technical solutions disclosed in the present invention in detail, further elaboration will be made below in conjunction with specific embodiments and the accompanying drawings.

[0074] One of the development priorities of future autonomous driving technology lies in the design of on-board edge computing products. Edge computing refers to an open platform that integrates network, computing, storage, and application core capabilities on the side close to the source of objects or data, and provides the nearest end services. Its applications are launched on the edge side to generate faster network service responses and meet the basic needs of the industry in terms of real-time business, application intelligence, security and privacy protection. Edge computing sits between the physical entity and the industrial connection, or on top of the physical entity. With cloud computing, historical data from edge computing can still be accessed.

Abstract

The invention discloses a reliable vehicle-mounted edge calculation unloading method based on reinforcement learning, which is used in scenes such as limited coverage of road side units (RSUs) caused by urban obstacles or insufficient calculation capability of the road side units, and a vehicle can perform reliable calculation unloading by means of an unmanned aerial vehicle (UAV). According to the method, a multi-objective optimization problem of maximizing system utility and minimizing power consumption is converted into two sub-problems of a power distribution problem and a calculation unloading problem, and task distribution and calculation are completed by the unmanned aerial vehicle and the road side unit together. According to the method, the chance constraint is created for the transmission power, the chance constraint is converted by using a Chebyshev inequality, the minimum transmission power is derived, and the reliability of task transmission is ensured. According to the method, the calculation unloading efficiency is improved through the improved deep reinforcement learning model, the predicted target Q value in the deep reinforcement learning model is adjusted by using the result of the multi-target optimization problem, and offline training and online updating of the edge server are realized.

Description

technical field [0001] The invention belongs to the technical field of communication of the Internet of Vehicles, and in particular relates to a method for unloading reliable vehicle-mounted edge computing based on reinforcement learning. Background technique [0002] Edge computing is one of the most promising technologies to provide powerful computing capabilities to vehicles, and in order for vehicles to respond quickly in complex traffic scenarios, it enables mobile vehicles to offload computing tasks to various edge servers, such as roadside unit and roadside unit. Due to incomplete coverage and intermittent connectivity in dynamic vehicular networks, it is a challenge to design a reliable and efficient computation offloading strategy. Due to the advantages of low price, easy deployment and flexible mobility, UAVs have been applied and developed in fields including but not limited to intelligent sensor data acquisition, target tracking, disaster area monitoring and com...
