Research Interesting

• IoT and Smart Home

The simple concept of Internet of Things (IoT) is to allow all the things in the world to connect and exchange data with each other. When we bring IoT technologies to domestic space, we can introduce a new comfortable living environment called “smart home” in which various domestic services such as home automation, smart lighting, smart air conditioner, etc. can be provided to home users. In a smart home, IoT devices collect and send data they obtain from the real world to service providers, who analyze the data and send control commands to IoT devices to provide services to home users. In this research, we work on an IoT platform, which can simplify the deployment of IoT devices and allow service providers to easily deploy their services on smart homes. We also work on the optimization problems for smart home services by utilizing various kind of sensor data effectively.

• Cyber physical system (CPS)

Recently, research on cyber physical system (CPS) attracts a lot of attention. In CPS systems, information of physical space is handled by computers in cyber space in order to optimize the operation of control systems, which then act upon physical space. A CPS system can optimize the operation of services in a smart home, an agricultural farm, etc. In this research, we work on building physical models, which can represent the state of physical space and allow computers to calculate solutions for optimization of system operation. We also implement systems which can realize the approach of CPS systems in real environment. In these real systems, environment data gathered by sensor networks, such as temperature, humidity, solar radiation will be sent to computers, which analyze the data based on physical models and send optimized control commands to actuators.

• Quality of Service (QoS) for IoT devices

With the scenario of billions of IoT devices connecting to the Internet, the type and the number of IoT applications also quickly increase. Different challenges may arise during the deployment of IoT applications including the diversity of applications requirements, the limitation of network resources and device resources, … In this research, we focus on a Software Defined Network-based framework, which can collect and analyze information from IoT devices and network devices and manage network devices to enhance the QoS of network access services provided to IoT devices.
