A cooperative unmanned vehicle network computing task offloading method

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 ...
