The size of data chunk diverges from 101 to 1010 bits. Generally, if a network carries in a way both of big size data and small size data, the performance is extremely degraded by the big size data. Then, we propose to select a wireless cell among of multiple cells by referring context information such as data size and user's situation such as moving velocity. Especially, we show the improvement on...
Cloud Radio Access Network (Cloud RAN) is novel mobile network architecture. It uses cloud computing capabilities to enhance the quality of service (QoS) in next generation 5G networks. The basic concept of Cloud RAN is to separate the digital baseband processing units (BBUs) of conventional cell sites, from the Remote Radio Heads (RRHs), and move them to the cloud for centralized signal processing...
Existing CAPTCHA methods are able to be read by computers owing to the development of technologies. We proposed a CAPTCHA method with amodal Completion in order to prevent computers from reading CAPTCHA. We also applied aftereffects and colors for the method to enhance visibility. However, our method was completely able to be read by computers with deep learning. However, we were able to discover...
In recent years, Intelligent Assistant services have come out to respond to user requests or to perform certain functions. These services get the request input from users with natural ways such as voice or text. However, the biggest hurdle of this approach is that it is very difficult for users to know the scope of the service (feature or knowledge) and therefore it is difficult to deliver the right...
This paper illustrates on the new Internet of ThingsConsortium as OCF stands for Open Connectivity Foundationthat is creating a specification and open source simultaneously tobe broadly adopted in various industries. OCF is a uniquespecification and open source project that delivers just-worksinterconnectivity for developers, manufacturers and end users.
Network traffic monitoring is an important factor to maintain stability and effective network management in software-defined networking (SDN). However, monitoring by current support of SDN architecture, i.e., OpenFlow, is neither flexible nor scalable due to the dependence to OpenFlow tables, which is designed mainly for forwarding. The scalability issue is even more serious when monitoring in network-wide...
Several vendors are developing sports clouds as part of recent developments in sports science and cloud computing. Currently available sports clouds focus on physical and technical data but not mental data. We propose a sports mental cloud, which manages mental data. The sports mental cloud stores big data collected in various psychological tests and analyzes the data in various ways. The sports mental...
The emerging requirements of large-scale Big Data applications are increasingly affecting server-oriented on-chip computing architectures. In particular, in order to exploit the full potential of highly parallel clustered on-chip interconnects, it is essential to carefully route inter-domain traffic that is one of the primary sources of performance degradation. In this paper, we propose a methodology...
