Optimization Method for Task Offloading Decision and Edge Resource Allocation in Distribution Networks
摘要
Abstract
Mobile edge computing can reduce the pressure of massive data transmission and processing in core distribu-tion networks,compared to cloud computing,the computing limitations of edge nodes poses a challenge to the efficient utilization of edge resources.Based on this,a task offloading decision and edge resource allocation optimization method in distribution networks is proposed.First of all,in a distribution network scenario containing multiple edge nodes and multiple user devices,a cloud-edge-end three-layer edge computing offloading and resource allocation model is constructed.Secondly,the optimization process is divided into two stages:computing offloading and resource auction.In computing offloading stage,an online decision algorithm based on DRL is proposed,and in resource auction stage,a multi round iter-ative auction mechanism based on compensation strategy is designed.Finally,a task offloading and resource allocation optimization method based on improved DQN algorithm is proposed.The simulation results show that the proposes algo-rithm can effectively improve system computing energy efficiency and edge node efficiency in dynamically changing dis-tribution network scenarios.关键词
