We are currently researching three types of topics. - Vehicular Networks, SDN/NFV, IoT/WSN
Below, we briefly introduce the related topics and write down the result about our researches.

Vehicular Networks and Smart City Research

Software Defined Networks / Network Functions Virtualization

Software Defined Networks (SDN) is conducted along with Network Functions Virtualization (NFV) research, which is network functional virtualization, to reduce infrastructure construction cost and operation cost for network service. SDN which separated by data and control planes uses a control server (i.e., SDN controller) to manage network devices flexibly and efficiently. This is an approach to control / manage the operation of network traffic transfer via software based controller using openAPI (e.g., openflow). Internet of Things (IoT) Lab implements SDN-based security service using Interface to Network Security Functions (I2NSF). We also contribute to the international standardization. Through this research, we will implement a SDN-based security service, provide it to the field, and standardize it.

Internet of Things / Wireless Sensor Networks

The Internet of things (IoT) is the network of physical devices, vehicles, building systems, and various embedded devices with electronics, software, sensors, and actuators that enable these objects to collect and exchange data. Recently, the IoT has become one of the hottest research fields. By a large number of devices, it is inefficient to manually configure their domain names in the Domain Name System (DNS), which allows DNS servers to translate between domain names and Internet Protocol (IP) addresses. We proposed the scheme of DNS autoconfiguration for IoT devices in IPv4 or IPv6 environment.
