Research Area

The objective of the Internet Architecture and Systems Laboratory (inet-lab) is to establish systems and applications in the following four noteworthy, Internet-wide areas from both theoretical and practical points of view:

Computer/network system management

Nation-wide internet 4K/8K video transmission

Advanced digital libraries with multimedia

Methodology for network traffic analyzation

Ubiquitous computing

Pedestrian navigation systems (Indoor positioning (Fig. 1), real world digital archiving, navigation interface)

Sensor data mining

Participatory sensing

Disaster relief computing/networking

DTN (Delay Tolerant Network) using small UAV (Unmanned Aerial Vehicle) for disaster relief (Fig. 2)

Mobile network operation for a satellite communication vehicles (Fig. 3)

Wireless mesh sensor networks

Information security: cryptography and network security

IoT (Internet of Things) security

Faster implementation of cryptography

Malware analysis (Fig. 4)

Privacy preservation and security risk management

CTF (Capture The Flag) Competitions

Key Features

In our laboratory, students can study a variety of topics concerned with computer networks, from the network layer to the application layer. The strength of our laboratory is that students have opportunities to perform their research using actual computer network environments because all faculty members are engaged in the Information Initiative Center (ITC) of NAIST. Additionally, in some cases we develop devices to create appropriate research environments. Our laboratory welcomes students of all levels of expertise, providing seminars on basic theoretical and practical studies as well as advanced areas.
