        USN 활용을 위한 계층형 서비스 설계 및 구현

        노창배,나원식,Roh, Changbae,Na, Wonshik 중소기업융합학회 2014 융합정보논문지 Vol.4 No.2

        RFID/USN은 u-Korea를 구현하는 핵심 인프라로서 무한한 성장 잠재력을 내포하고 있으며 향후 인터넷에 이어 산업 전반에 커다란 변혁을 가져올 수 있는 분야로 대두되고 있다. 우리나라의 경우 u-Korea 비전과 세계적인 RFID/USN 기술을 확보하여 세계 시장을 선점하고자 하는 IT839 정책에 따라 RFID/USN에 대한 관심도가 사회 전반적으로 증대되어 USN에 대한 연구가 활발히 이루어지고 있으며 앞으로 USN 인프라 구축이 완료됨에 따라 USN을 활용하기 위한 USN 어플리케이션들이 빠르게 증가할 것이다. USN 인프라 기반의 어플리케이션 개발을 보다 손쉽게 하기 위해 USN 미들웨어의 필요성이 대두되며 디렉토리 서비스는 USN 미들웨어를 구성하는 핵심 서비스 중의 하나이다. 그러나 USN 구성요소인 WSN의 특성 등을 고려할 때 USN 인프라에 적합한 디렉토리 서비스는 검색에 중점을 둔 기존의 디렉토리 서비스와 달리 갱신문제가 나타날 수 있으며 본 논문은 이를 극복할 수 있는 디렉토리 서비스의 설계 및 구현에 대해 논한다. Connotation and unlimited growth potential as the core infrastructure to implement the u-Korea RFID/USN is emerging to lead to a future Internet that can bring a huge transformation in the industry sector. On RFID/USN increase overall social interest of our country, if the world who want to dominate the market by securing the u-Korea vision and global RFID/USN technologies IT839 depending on the policy, has been active research on the USN and USN infrastructure in the future building is completed as quickly to take advantage of the USN. USN applications will increase. Of USN middleware and necessitate USN infrastructure-based application development in order to more easily USN middleware configuration directory service is one of the core services. USN infrastructure suitable for the directory service when considering the characteristics of WSN, such as the USN components, update existing directory services and search focused on the problem and receive, this paper can overcome this directory service design and implementation discussed.

      • JNDI를 이용한 Mobile Agent 기반 망관리시스템

        김정철,김강석,송왕철 濟州大學校 産業技術硏究所 1999 산업기술연구소논문집 Vol.10 No.2

        Recently, network management technology by delegation has been studied as a kind of network management technology to satisfy the user's requirements. Mobile Agent in the technology issues in the distributed network system. Mobile Agent is a software program which is able to move on network with mission for managing a NE(Network Element). Therefore. We have studied the efficient network management technology which is the network management system based upon Mobile Agent Using JNDI(Java Naming Directory Interface). JNDI is API(App1ication Program Interface) to support interface which make user's application program to be used the naming & directory service. We have designed and implemented the mobile agent network management system using JNDI. This Mobile Agent system is expected to provide a solution for the conventional centralized network system.

        광고를 동반한 소셜 네트워크 이름-디렉터리 서비스의 실험적 데이터 분석

        김영복(Yung Bok Kim) 한국IT서비스학회 2014 한국IT서비스학회지 Vol.13 No.4

        With the evolution of Internet technologies and the increasing variety of Internet devices, advertisements in various web services have also expanded. Interactive web services often go hand in hand with effective advertisements for a business model. We estimated statistical parameters of the interactive web server for service monitoring and advertisement-effect. In the web pages, we integrated the plugins of social networking services (SNSs) (e.g. Facebook, Twitter) and an advertisement scheme (e.g. Google AdSense) that regards social name-directory contents. Empirical data analysis and statistical results are presented with the implementation of estimations of parameters (e.g. utilization-level and serviceability) and advertisements in a social networking name-directory service (http://ktrip.net or http://한국.net). We found that estimated parameters were applicable to service monitoring of web-server as well as to synthesis of advertisement-effect in our social-web name-directory service.
