Design And Implementation Of Embedded Resource Adaptive Computing Framework

With increasing the number of edge devices and sharp increase of computing power in edge computing,a large number of computing is placed on terminal devices and edge devices with different types of devices,different processing capabilities and different loads,forming a collaborative computing status of terminal edge cloud,bringing about the problem that same software can't adapt to the resource differences of devices.Adaptation problem becomes an important problem in edge computing.Aiming at the problem of resource adaptation and resource adaptive software development caused by huge difference of equipment resources in edge computing,this paper studies the framework of embedded resource adaptive computing,which focuses on the breakthrough of embedded resource sensing technology,embedded resource adaptive decision algorithm and embedded software dynamic adjustment technology,and designs a set of computing framework for embedded resource automatic adaptation.At the same time,we design and develop a prototype system under typical business scenarios to verify the effectiveness of the adaptive framework.First of all,based on the analysis of related technologies,this paper studies the embedded resource sensing technology,embedded resource adaptive algorithm,embedded software dynamic adjustment technology.Then,an embedded resource adaptive computing framework is designed and implemented.The hierarchical architecture of the adaptive framework is designed.The interface layer,the core processing layer,the basic support layer and the spring boot support layer of the adaptive framework are implemented respectively,using the key value pair model to represent resources,proposed rule-based resource adaptive algorithm and control theory based resource adaptive algorithm,and provided multiple annotations to facilitate the expansion and use of the adaptive framework.Finally,a prototype system is designed to verify the effectiveness of the adaptive framework.Based on adaptive framework proposed,the system architecture of the prototype is designed,and picture service component and computing service component are developed.Results show that the framework can select service implementation according to the changes of network resources and CPU resources,and effectiveness of adaptive framework is verified.
