AboutAbout the lab
Building communication and power supply systems
The Sekiya-Nguyen Lab aims for a new information and communication society that is mindful of energy and environmental issues, and studies wireless communication, power supplies for communication equipment, and neural networks.
The lab works on communication methods that use multiple communication paths, power supply circuits that reduce power loss, and research toward making IoT networks AI-enabled.
All of its research concerns the design and construction of "systems," and the lab places importance on always backing mathematical analysis with experimental demonstration.
Key terms
- Multipath TCP
- A mechanism that extends the Internet communication protocol (TCP) so that data is sent over multiple communication paths at the same time
- Wireless power transfer
- A technology that sends electricity to distant devices using radio waves, magnetic fields, or similar means, without connecting wires
- Spiking neural network
- A computational model that more faithfully imitates how neurons in the brain communicate through pulses of electrical signals

ResearchResearch themes
Under the theme "Toward a new information and communication society that is mindful of energy and environmental issues," the lab studies wireless communication, power supplies for communication equipment, and neural networks. All of its research topics concern the design and construction of "systems."
*Illustrative imageCommunication over multiple paths
The lab leads worldwide research and development on Multipath TCP, which improves the communication protocol TCP so that data is sent over multiple paths, such as wireless and optical links. It also aims to build an electronic payment system for buying and selling environmental information collected by IoT.
*Illustrative imagePower supply circuits and energy and environmental issues
This research aims to reduce power loss in power supply circuits that convert renewable energy into usable electricity. The lab works on wireless power transfer systems and power supplies for EVs, and also develops software for designing low-loss power supply circuits.
*Illustrative imageIntelligent IoT networks
This research integrates IoT networks with spiking neural networks to perform intelligent information processing inside the network. It aims to eliminate the need for servers and greatly reduce power consumption.
