Abstract

The invention discloses a V2V mode multi-task unloading method and system based on mobile edge computing. The V2V mode multi-task unloading method comprises the steps that a vehicle system network isconstructed; according to a multi-hop V2V link indicator model in a vehicle system network, a vehicle user acquires a V2V reliable link during data transmission; the vehicle user sends a task unloading request to an MEC server to which the RSU of the road section where the vehicle user is located belongs according to the V2V reliable link, and the MEC server solves an optimal multi-task unloadingstrategy by utilizing a task unloading overhead model meeting time delay; and the MEC server sends the optimal multi-task unloading strategy to an RSU, the RSU sends the optimal multi-task unloading strategy to a vehicle user, and the vehicle user unloads a corresponding task according to the optimal multi-task unloading strategy. The task calculation cost is reduced to the maximum extent, the Internet of Vehicles service performance is improved, and the whole process is standard and easy to operate.

Description

technical field [0001] The present invention relates to the field of wireless communication science and technology, in particular to a V2V mode multi-task offloading method and system based on mobile edge computing. Background technique [0002] With the rapid growth of global vehicle users and the increasing service requirements of vehicle users, the Internet of Vehicles network bears more business data challenges such as high network transmission bandwidth requirements, high transmission reliability, and strong data processing capabilities. The enhanced network capability expansion of the Internet of Vehicles is crucial to the development of future Internet of Vehicles technology and intelligent transportation systems, and directly affects the safety of people's normal production, life and travel. The explosive communication data volume processing caused by the sharply increasing vehicle user service demand is one of the key problems that must be solved in the current Inte...
