Description

technical field [0001] The invention relates to a mobile edge computing offloading delay optimization method, device and storage medium, and belongs to the technical field. Background technique [0002] Task offloading means that users offload tasks that cannot be processed to the data center for processing. Resource allocation mainly refers to the allocation of wireless channels, wired channels, server computing and cache resources. Task offloading is closely related to resource allocation problems. After making task allocation decisions, the rational allocation of resources must be considered. For example, when tasks are offloaded, how many wireless channels or time slots are allocated in the radio access network to transmit them, how much bandwidth the wired channels need to be allocated in the backhaul network, and how much computing resources are ultimately allocated by the data center to process the task. All these require reasonable planning to effectively utilize ...
