  9. Performance of Heterogeneous Wireless Networks i) Power, rate, and carrier sense threshold control: To increase the level of spatial reuse in multi-hop wireless networks. ii) Interference aware routing and scheduling: To improve overall network capacity by exploiting temporal-spatial diversity.iii) Contention control for wireless sensor networks: To utilize the wireless channel effectively by adjusting the channel access probability. Web interface model i) Remote control: Online upload or scenario files and application files on wireless node ii) Automation of experiment process: Real time auto collection of traffic traces and debugging messages.

  10. Auto-configuration for Mobile Objects • 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) Service Type A 6LoWPAN GW WHO AM I? (Addr Autoconf) Initial Monitoring Service Monitoring Service 6LoWPAN GW Movement Combining Basic Two Queries Service Type B Type Based Address Configuration and Service Discovery

  11. IP-USN and 6LowPAN

  12. 6LowPAN Interworking Testbed in KOREN 2001:2b8:f2:2::3 2001:2b8:f2:2::3 2001:2b8:f2:2::3 2001:2b8:f2:2::3 2001:2b8:f2:2::3 2001:2b8:f2:2::3 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 2001:2b8:f2:2::4 • KOREN is a research network based on QoS/Multicast/ IPv6/MPLS established in 1995 • Connected to APII Testbed (Japen, China), TEIN2(Europe). • 6LowPAN Interworking testbed in 6 open test facilities in 6 major cities in Korea DWDM/OADM ATM Switch Router Gigabit Switch 35Gbps 2.5Gbps 155Mbps Seoul Suwon Daejeon Daegu Busan Gwangju

  13. Target Issues in USN Resource efficient sensor network architecture and protocols Wireless Sensor networks • ARP for sensor network service • Sensor node architecture based on ARP • Energy efficient MAC/Routing protocol • QoS issue of MAC/Routing protocol • Tiny scale OS Sink node (Gateway) Ethernet/ Optical WiBro/ Cellular KOREN Efficient interconnection between non-IP sensor networks and IP networks Oversea Network (EU, US, JP, etc) • Cooperative network architecture • Efficient data delivery • Addressing Issue • Sink node discovery • Mobile sink node IP-USN Commercial IP networks * Application
