Embodiment Construction

[0061] The following is a detailed description of the embodiments of the present invention. This embodiment is carried out based on the technical solution of the present invention, and provides detailed implementation methods and specific operation processes to further explain the technical solution of the present invention.

[0062] The unmanned aerial vehicle collaborative computing task offloading method for the Internet of Vehicles provided in this embodiment specifically includes the following steps:

[0063] Step 1. The mobile edge computing server receives computing tasks offloaded by the Internet of Vehicles. If it exceeds its own computing capacity, it is determined that the mobile edge computing server is an overloaded server; otherwise, it is a non-overloaded server; the amount of computing tasks that exceed its own computing capacity is Overload computation.

[0064] Step 2: The overload server sends a help signal to the UAV based on its own overload computation. ...

Abstract

The invention discloses an unmanned aerial vehicle cooperative computing task unloading method for the Internet of Vehicles, comprising: a mobile edge computing server receives computing tasks unloaded by the Internet of Vehicles, and if the computing task exceeds its own computing tolerance, the mobile edge computing server is determined to be an overload server , otherwise it is a non-overloaded server; the overloaded server sends a help signal to the UAV based on its own overloaded calculation amount; The original optimization problem is constructed with its own long-term energy consumption as the constraint condition, and the cooperative strategy is obtained for the overload calculation of all overloaded servers by converting and solving the original optimization problem. The present invention can alleviate the overload problem of the mobile edge computing server caused by the unbalanced distribution of unloading computation.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to an unmanned aerial vehicle cooperative computing task offloading method for the Internet of Vehicles. Background technique [0002] In recent years, the increase in the number of vehicles and the increasingly mature interconnection technology have spawned many emerging vehicle applications, such as: autonomous driving, in-vehicle entertainment, etc. Most of these applications have high requirements on latency and require a lot of computing resources. However, the limited computing power of a single vehicle is difficult to complete the timely processing of these applications. In this case, the user experience quality of the vehicle is always very low. [0003] The emergence of mobile edge computing servers provides the possibility to solve the above dilemma. The mobile edge computing server has strong task processing capabilities and is relatively ...
