Research

Wireless systems hide limitless possibilities that can enrich our lives, as said by the father of wireless communications, Guglielmo Marconi, "It is dangerous to put limits on wireless." We are aiming to realize new communication networks through wireless access and multi-hop communications, based on communications theory, network architecture and signal processing. Specifically, we undertake research on access control for effectively sharing limited radio resources, network control for cooperative connections and signal processing for high quality communications, for distributed autonomous systems such as sensor and ad hoc networks.

Theme1:Wireless Networks

Overview

In wireless networks, especially distributed autonomous networks such as sensor and ad hoc networks, it is crucial to keep connectivity high for delivering more data with low latency, and also to save energy for longer time operation. We are aiming to design and build medium access control and topology control protocols so as to utilize and manage wireless resources efficiently for the use of the emerging IoT or trillion sensors universe.

Keywords

MAC protocol, topology control, multi-hop communications, energy efficiency

Theme2:Sensing Systems

Overview

A sensor which converts physical quantities to electrical signals can be a sensing system and create new services when a lot of sensors are assembling together and connecting each other, besides having processing and communication functions. We are aiming to develop new sensing systems exploiting radio wave propagation characteristics such as localization for mobile objects including sensors and persons, and also for resonator’s location estimation in wireless multi-hop power transfer systems.

Keywords

mobility sensing, radio propagation characteristics, localization

Theme3:Full Duplex Multi-hop Communications

Overview

Communication traffic is rapidly growing as widely spreading wireless tools and sensors, which causes wireless resources a critical shortage. In-band full duplex communications can double the capacity in principle than half duplex communications used in current wireless LAN etc., however it must suppress self-interference. In addition, no protocols have been designed for multi-hop communications. We are aiming to develop a self-interference canceler and access protocol for in-band full duplex multi-hop communication systems that can efficiently utilize wireless resources by spatial-temporal control.

Keywords

in-band full duplex communications, self-interference canceler, multi-hop communications, spatial-temporal control
