  3. KOREN Overview • KOREN : KOREA Advanced REsearch Network • Non-profit research network • Funded by Goveronment [MIC] • Established in 1995 • NIA participate from 2002 • Support Network Service & R&D Porjects • Currently, 81 R&D Institutions • 9 funded R&D Projects in 2007 • o MIC : Ministry of Information and Communications • o NIA : National Information Society Agency

  4. Network Facilities • 6 Giga PoPs • PoPs : Seoul, Daejeon, Daegu, Pusan, Kwangju, Suwon • 5 Open Test-beds • Seoul (NIA), Daejeon (ICU), Daegu, Pusan, Kwangju • 10G ~ 20Gbps backbone • Seoul – Daejeon: 20G • Daegu – Daejeon - Kwangju - Pusan: 10G • Seoul – Suwon: 10G

  10. Initial Monitoring Service Application Projects (1) • Limitations of memory and processing power  Sensors do not have enough descriptions for service discovery KOREN The Internet Service Directory WHAT IS AVAILABLE? (Service Discovery) 6LoWPAN GW WHO AM I? (Addr Autoconf) Monitoring Service 6LoWPAN GW Movement Service Type B Combining Basic Two Queries Type Based Address Configuration and Service Discovery

  11. Application Projects (2) Testbed Project Performance evaluation . TCP/UDP Data Throughput, Delay, Multi-hop analysis . Mesh management routing Algorithm . TCP PlanetLab Over KOREN . PlanetLab Testing over KOREN Consortium: SNU, HP-USA (Mobile Media System Lab) Testbed Configuration . SNU Mesh – KOREN – Abilene - HP Mesh . SNU PlanetLab node – KOREN – Abilene - HP PlanetLab node

  12. Application Projects (3) Testbed Project WMN based multi-hop, Multimedia transmission technology . HD multimedia data transmission technology on Wireless and wired convergence network Scheduling technology for minimum interference in WSN network Consortium: GIST, SKU, OSU, UIUC Testbed Configuration . WMN with KOREN interconnected Server Routers IEEE802.15.4/Zigbee-based Sensor node Testbed (7X7 Grid Topology) . GIST-KOREN-SKU

  13. Application Projects (4) Welfare Support System for u-Lifecare DataBase Management Analysis Action Pattern (Acceleration + Location Data) IT Village (High-Speed Network) ④ Providing Services (Web) Real-Time Information Monitoring 911 ZigBee Gateway Vaious Sensers (Including Image Sensors for Patients with Severe Dementia) ③Server Transmission (KOREN) Family Nursing Homes Location Detection (Using Ultrasonic Data) Service Server DataBase Management ① Information Sensing Medical Doctor KOREN Data Transmission (Sensor ↔ KOREN) FTTH(100M) Analysis Action Pattern (Using Acceleration Data) ②Information Collection Interface (for Wireless Device) House of Living-Alone Elderly Person APII Gloriad Senior Hospitals

  14. Application Projects (4) Welfare Support System for u-Lifecare

  15. Application Projects (5) < ETRI Kwangju FTTH > <Seoul> QSS120 • FTTH Service System • IPTV (multicast) • VoD • e-Learning • Private TV • etc… Router STB <Y.I> QSS120 KOREN STB <Pusan> <Daegu> <Daejeon> QSS120 QSS120 QSS120 STB STB STB

  16. Remarks • From 2008, NIA will manage both KOREN and APII/TEIN2 in Korea. • Need to collaborate with Asian researchers, and identify international research activities in application areas.
