Research On Computation Offloading Mechanism In Edge Computing Network Based On Security Management

In order to deal with the problem of insufficient processing capability and limited resources of terminal equipment,the concept of computation offloading in edge computing is proposed.Edge computing network refers to a solution that deploys computing and storage resources at the edge of a mobile network to provide an IT service environment and cloud computing capabilities for mobile networks,which provides users with ultra-low latency and high bandwidth network services.The computation offloading technology in edge computing offloads the computing tasks of the terminal equipment into the edge cloud environment,which solves the shortcomings of the device in resource storage,computing performance and energy efficiency.In addition,compared with the computation offloading in traditional cloud computing technology,computation offloading in the edge computing network also solves the problems of long calculation delay and network resource occupation.Although the computation offloading technology in the edge computing network solves the problem of limited resources of mobile devices,it exposes a series of problems in security.A malicious offloading task can cause the edge network resources to be occupied,causing the network unable to provide computing services for normal users.Therefore,it is necessary to design reasonable safety offloading measures.Although academia and industry have done a lot of research work on edge computing and computation offloading technology,most of the work is to consider how to design a reasonable computing offloading scheme from the aspects of energy consumption and delay.In the existing computing offloading scheme,there are fewer computing offloading schemes considering security.Therefore,combined with the MEC network architecture,this paper proposes a security-based edge computing network architecture,and proposes a trust management mechanism in the process of computing offloading.Then,a security-based computing offloading scheme in edge network is proposed,which solves the problem of offloading decision and resource allocation,and provides a secure and reliable computing uninstallation scheme.The optimal offloading decision matrix and resource allocation strategy are computed through QEA algorithm and d selection algorithm.Finally,thr-ough the analysis and comparison of the simulation results,the advantages of this scheme over performance,safety,delay and energy consumption are compared.
