Abstract

The invention discloses an energy-efficient and resource-limited mobile edge computing task allocation method, which comprises the following steps: establishing a joint optimization model based on energy consumption and processor resource waste according to different task allocation schemes and the influence on energy and processor resources of edge clouds under the condition of stipulated execution delay; further minimizing total energy consumption of task allocation and processor resource waste under the condition of stipulating execution delay, then mapping the joint optimization problem into an ecosystem model of a biogeography algorithm, and obtaining an optimal task allocation scheme according to a corresponding optimization target and a corresponding optimization condition; according to the invention, the problem that the mobile user equipment with limited resources cannot meet the resource requirements of the mobile application is solved, the mobile user equipment can unload part of tasks forming the mobile application to the base station or the edge cloud of the mobile edge computing, and the energy efficiency of the edge cloud and the resource utilization rate of the processor are improved.

Description

Technical field: [0001] The present invention relates to mobile edge computing, in particular to an energy-efficient and resource-constrained mobile edge computing task allocation method. Background technique: [0002] Mobile Edge Computing (Mobile Edge Computing) provides cloud services by pushing cloud resources (such as computing, network, and storage) to the edge of the mobile network, and integrates wireless networks and applications, making traditional wireless access networks intelligent and application-friendly. The conditions for localization and short-distance deployment provide high-bandwidth and low-latency transmission capabilities. The schematic diagram of the environment is as follows figure 1 shown. There are six parts in this diagram: (1) mobile user equipment; (2) wireless cellular base station; (3) tasks (Tasks, Ts) assigned to virtual machines (Virtual Machines, VMs) and containers (Containers, Cs) ); (4) edge servers and cloud servers with built-in vir...
