Mobile IoT Simulation Experiment Platform Based On Container Virtualization Technology

With the development of the mobile Internet of Things,virtualization technology has played an increasingly important role in improving network performance and increasing network flexibility.Among them,the container virtualization technology shows the advantages of efficient resource utilization,fast system startup,and easy maintenance and expansion.However,the experimental environment of the mobile Internet of Things still has three problems: 1.The current Internet of Things simulation experiment environment is not containerized,the deployment of simulation experiments is complicated,and resource utilization affects the experimental results;2.The existing Internet of Things simulation experiment environment is only limited The local resources do not support mobile network scenarios,and the rich distributed resources cannot be used;3.Lack of an effective platform framework for overall management of the experimental environment,and the configuration and evaluation of the experiment is more inconvenient.In response to the above problems,this thesis designs and implements a mobile Io T simulation experiment platform based on container virtualization technology.The main contributions of this thesis include:(1)Improve the scalability of the Internet of Things simulation experiment.This thesis migrates the existing simulation experiment environment of the Internet of Things to the container,and deploys the container to the orchestration platform Kubernetes in the form of an image,so that the platform supports the simulation experiment of the Internet of Things.Compared with the experimental platform based on virtual machine technology,the Io T simulation experiment environment designed in this paper effectively reduces the CPU and memory overhead of the experiment,and improves the scalability of the experiment.The experimental results show that using the same physical resources,the platform proposed in this paper can simulate 5 times more Io T nodes than the platform based on virtual machines.(2)Increase the experimental platform to support cellular mobile experiments.By introducing the cellular network simulation tool Open Air Interface,the experimental platform mentioned in this article adds support for mobile network scenarios.Since cellular network simulation is also implemented in the virtual environment provided by the cloud platform,it has higher efficiency than direct deployment on the physical host.The experimental results in this article verify the fidelity of the cellular simulation on the cloud platform and ensure the network performance of the mobile network experiment.(3)Designed and implemented an experiment management platform based on B/S architecture.This paper designs and implements a simulation experiment platform that includes Open Stack and Kubernetes clusters.The two clusters are used to manage virtual machines and containers.The platform is based on the open APIs of Open Stack and Kubernetes and can support simultaneous experiments by multiple users.Through the optimization of the experiment process,the operation of the experimenter is simplified,and it is convenient for the experimenter to configure and evaluate the experiment.
