RESEARCH

Network Computing Laboratory (NCLAB) conducts research on a variety of networking and computing technologies, including edge computing, container orchestration, Internet of Things, and edge AI. To realize IoT Edge service infrastructure, we’ve recently focused on federated learning technologies combined with edge computing. We have extensive experience with open source projects like Kubernetes, KubeEdge, Flower, and SUMO.

Current Research Topics

Edge AI – Federated Learning on edge computing environment

Federated learning is a distributed machine learning paradigm that allows users to learn global models by just providing trained weights to the server. Federated Learning may take advantage of the potential of dispersed data without transferring it to a central server. It has been highlighted as a potential technology that can significantly lessen worries about user data, such as privacy, GDPR rules, and so on. The goal of this project is to create an edge computing infrastructure based on a representative open-source platform and to undertake various studies on federated learning approaches like as:

  • Performance evaluation of federated learning algorithm in edge computing environments.
  • Research on dynamic resource provisioning and load balancing algorithm to improve federated learning.

  • Research on the improved federated algorithm in edge computing environments.
Container orchestration for IoT Edge service infrastructure
IoT edge service infrastructure enables that users can freely install and execute IoT services dynamically at the edge gateway, which significantly reduces the computation cost and network traffic overhead. Container orchestration technology is a core technology for realizing the IoT edge gateway architecture. These are our main researches on container orchestration and IoT edge service infrastructure.
  • High scalable and availability of Kubernetes auto-scaling
  • Load balancing of Kubernetes cluster toward high scalability
  • Integration with SDN/NFV for intelligent control of IoT infrastructure
  • Network aware resource orchestration for IoT infrastructure

Edge simulation and testbed

Our research on edge computing and federated learning is aimed at developing an intelligent CCTV camera system and autonomous vehicle systems. Various performance evaluations of the suggested notion will be undertaken using edge testbeds and simulations. Especially, the SUMO simulation framework is used for the development and verification of federated learning techniques in mobile vehicles and intelligent transportation systems.
