The lab researches networks that make communication in smart cities comfortable and secure.

AboutAbout the lab
What kind of network infrastructure supports smart cities?
The Miyata Lab researches communication traffic analysis and information security as part of the network infrastructure needed to realize smart cities.
The lab also develops mechanisms that use data on the behavior of people and devices to control communication quality more flexibly.
The lab started in April 2024, and has also published jointly authored international papers with the University of Glasgow and Loughborough University in the UK.
Key terms
- Traffic
- The amount of communication flowing through a network. When there is too much, the network becomes congested and communication is delayed.
- Edge computing
- A mechanism in which data is processed not on a distant server but on computers close to users or sensors.
- Digital watermarking
- A technology that embeds information such as copyright data in images and other content with almost no change in appearance.

ResearchResearch themes
Under the theme of the network infrastructure needed to realize smart cities, the lab researches communication traffic analysis and information security. By incorporating the behavior of people and devices into network control, it aims to establish human-centered network control that is comfortable and sustainable across an entire city.
*Illustrative imageMonitoring and Incentive Design
Based on data on the locations and behavior of people and vehicles collected in cities, the lab researches methods to automatically select communication methods and connection destinations. It also designs reward mechanisms (incentives) that encourage people to participate in data collection.
*Illustrative imageCommunication Traffic Analysis
In edge computing, where data from cameras and sensors is processed on nearby computers, the lab researches ways to reduce waiting time by adjusting the order and location of processing. It also analyzes communication delays using queueing theory.
*Illustrative imageInformation Security
The lab theoretically analyzes the risks of access control for preventing information leaks, and proposes digital watermarking that embeds copyright protection information in images. It also researches methods for detecting DDoS attacks on IoT devices with little computation.
