Recently, the software defined networking (SDN) technologies have been highlighted because these are not only the alternative to improve the legacy network efficiency, but also the power source to develop the new business ecosystem. Most of all, the SDN technique can be used in several areas because it is one of the software technology. However, the SDN(More)
This paper proposes a non-contact plant growth measurement system using infrared sensors based on the ubiquitous sensor network (USN) technology. The proposed system measures plant growth parameters such as the stem radius of plants using real-time non-contact methods, and generates diameter, cross-sectional area and thickening form of plant stems using(More)
As heterogeneous wireless networks are deployed and users need more flexible mobility services, there has been a lot of research work about interworking mechanism between widely deployed 3G network and rapidly boarded WLAN. On the other side, WiBro is newly commercialized in Korea as the next generation wireless network. WiBro is based on IEEE 802.16e and(More)
In order to provide WiMAX network services to specific purposed devices such as credit card systems and surveillance systems, we have proposed a new non-PC/SC based mini WiMAX Connection Manager (non-PC/SC m-WCM) that can be applied to small hardware system or architecture with Micro Controller Unit (MCU). The existing legacy WiMAX Connection Managers(More)
In the Internet of Things (IoT) networking, numerous objects are connected to a network. They sense events and deliver the sensed information to the cloud. A lot of data is generated in the IoT network, and servers in the cloud gather the sensed data from the objects. Then, the servers analyze the collected data and provide proper intelligent services to(More)
