  • The brain-machine interface(BMI) is a next-generation interface that controls the device by decoding brain waves(also called Electroencephalogram, EEG), EEG is a electrical signal of nerve cell generated when the BMI user thinks of a command. The brain-machine interface can be applied to various smart devices, but complex computational process is required to decode the brain wave signal. Therefore, it is difficult to implement a brain-machine interface in an embedded system implemented in the form of an edge device. In this study, we proposed a new type of brain-machine interface system using IoT technology that only measures EEG at the edge device and stores and analyzes EEG data in the cloud computing. This system successfully performed quantitative EEG analysis for the brain-machine interface, and the whole data transmission time also showed a capable level of real-time processing.

  • Recently, the research relative to NGN(Next Generation Network) is progressing in 3GPP(The 3rd Generation Partnership Progect), IETF(Internet Engineering Task Force), and so on. Although user needs frequently mobility which is various service pattern, In accordance with the development of these various applications, IMS(IP Multimedia Subsystem) and hierarchical networks ie, Femtocell/WiBro/3G etc is constructed for more user demands which provide service in anytime, anywhere. It is necessary to optimum network selection criterion which consider to wireless signal quality add to user service profile and service network traffic balance. NGN also needs a method to perform heterogeneous handover and to constraint Ping-pong phenomenon when using existing terminal-based handover decision. This paper proposes scheme for network selection and heterogeneous handover procedure in hierarchical wireless multi-access network based on SIP-MIH(Session Initiation Protocol-Media Independent Handover) with IMS by using user service profile that the considerations are dealing with not only selection and registration of various access network but also easy of developing the terminal.

  • ICN (Information-Centric Network) is a next generation Internet communication technology for converting existing Internet communication paradigm to information-based communication paradigm to efficiently use a large amount of information that exists on the Internet. Therefore, unlike existing Internet communication technologies focused on the process of communication using the host address, ICN focuses on the purpose of communication for each information by defining the information of everything that exists on the Internet. For this purpose, ICN uses NbR (Name-based Routing) methods that assign a name to each piece of information, all routers participating in ICN have the physical storage so that they are able to share information with each other. NbR methods on ICN are divided into one-phase routing and two-phase routing depending on how to reach at the storage of each router. However, currently proposed NbR methods cause many problems because they do not reflect the unique characteristics of ICN. Therefore, this paper looked at various NbR issues from caching, access time, distribution, mobility, scaliability, and dissemination of information for an efficient NbR method, and analyzed existing methods proposed for ICN. This paper also proposed a research direction to study the efficient NbR for ICN based on the analysis information.

  • Millimeter-wave (mmWave) and Non-orthogonal multiple access (NOMA) are expected to be the major techniques that lead to the next generation wireless communication. NOMA provides a high spectrum efficiency by sharing of spatial resources among users in the same frequency band. Meanwhile, millimeter-wave gives a huge underutilized bandwidth at extremely high frequency band (EHF) which covers 30GHz to 300GHz. These techniques have been proven in several recent literatures to achieve high data rates. The combination of NOMA and millimeter-wave techniques further improves average sum capacities, as well as reduces the interference compared to conventional wireless communication systems. In this paper, we focus on hybrid NOMA system working in millimeter-wave frequency. We propose a clustering algorithm used for a hybrid NOMA scheme to optimize the usage of wireless resources. The proposed clustering algorithm adds several conditions in grouping users and defining clusters to increase the probability of the successful superposition decoding process. The performance of the proposed clustering algorithm is investigated in hybrid NOMA system and compared with the conventional orthogonal multiple access (OMA) scheme.

  • As XML emerging as the Internet electronic document language standard of the next generation, the number of XML documents which contain vast amount of Information is increasing substantially through the transformation of existing documents to XML documents or the appearance of new XML documents. Consequently, XML document retrieval system becomes extremely essential for searching through a large quantity of XML documents that are storied in and managed by DBMS. In this paper we describe the design and implementation of BADA-IV/XML query processor that supports content-based, structure-based and attribute-based retrieval. We design XML query language based upon XQL (XML Query Language) of W3C and tightly-coupled with OQL (a query language for object-oriented database). XML document is stored and maintained in BADA-IV, which is an object-oriented database management system developed by ETRI (Electronics and Telecommunications Research Institute) The storage data model is based on DOM (Document Object Model), therefore the retrieval of XML documents is executed basically using DOM tree traversal. We improve the search performance using Node ID which represents node's hierarchy information in an XML document. Assuming that DOW tree is a complete k-ary tree, we show that Node ID technique is superior to DOM tree traversal from the viewpoint of node fetch counts.

  • 인터넷의 도입 및 확대가 활발하게 이루어지면서 보다 많은 이용자들은 홈 네트워킹 기반의 정보 가전 기기, 텔레매틱스, 전자 물류 실현을 위한 전자 태크(RFID), 센서 네트워킹 등 모든 사물이 상호 통신할 수 있는 다양한 서비스를 요구하고 있으며 이를 해결하기 위한 연구가 활발히 진행되고 있다. 그러나 현재인터넷의 기반이 되고 있는 IPv4 주소 체계는 약 43억 개의 주소를 생성할 수 있도록 설계되어 있으며, 그 동안 비효율적인 주소 할당으로 유효한 주소는 불과 5~6억 개 정도만을 사용할 수 있는 실정이다. IPv4 기반의 인터넷 주소 체계로는 앞으로 도래할 유무선 통합 서비스 혹은 방송과 통신이 융합되는 사용자 중심의 인터넷 서비스 네트워크 구축에 많은 문제점을 갖고 있기 때문에 주소 자원을 거의 무한대로 제공하는 IPv6 기반의 인터넷(128비트 IPv6 주소는 2128개의 주소 지원) 도입이 필수적이다. 따라서 현재 IPv4 기반의 인터넷에서 IPv6 기반의 차세대 인터넷으로 전환되고 있으며, 또한 라우터 장비 시장은 차별화된 IPv6 기능을 제공하는 장비 중심으로 재편될 것으로 보인다. 본 고에서는 IPv6 라우터에 대한 IPv6 도입 배경 및 프로토콜에 관련된 제반적 기술을 살펴 보고, 이를 기반으로 외국 시스템들의 현재 구현 상태, IPv6 라우터를 개발하는 데 연구되어야 할 주요 사항 및 국내외 IPv6 도입 추진 현황을 살펴 본다.

  • Proxy Mobile IPv6 (PMIPv6)는 Mobile Node (MN)가 스스로 이동성을 지원하지 않더라도 Mobile Access Gate가 MN대신 이동성을 처리하여 IPv6 이동성을 지원하는 기술이다. 좀 더 향상된 핸드오버 성능을 얻기 위해 Proxy Mobile IPv6에서도 버퍼링을 통한 패킷 손실을 줄이는 기법을 사용할 수 있다. 하지만, IEEE 802.11 네트워크에서는 Handover 발생 직전에 MN이 어떠한 통보도 AP로 하지 않기 때문에 Handover시에 패킷 손실을 줄이기 위한 패킷 버퍼링 방법을 사용하기가 어렵다. 본 논문에서 PMIPv6에서 MAG와 AP가 MN의 이동성을 감지하여 버퍼링을 시작하고 Handover가 발생하였을 경우에 대비해 버퍼링을 하는 Cross-layer 버퍼링 방법을 제안한다. 이를 통해 PMIPv6에서도 MN의 변경 없이 Handover시에 발생하는 패킷 손실을 최소화 할 수 있다. 또한 간단한 성능 비교를 통하여 제안 방법이 기존 PMIPv6보다 우수함을 알 수 있다.
