  1. OKI Project Phase 2ITS World Congress Demonstration Department of Electrical and Computer Engineering The Ohio State University 2 August 2004

  2. Intersection Warning Demonstration

  3. Intersection Warning Demonstration • 2 computers simulate vehicles moving randomly through an intersection • Generate vehicle trajectory through the intersection • Transmit warning messages using 802.11b and 5.8 GHz • Receive and process messages from other “vehicle” and repeater • Send vehicle positions, trajectories, wireless transmission flags, and transmission times using LAN • 1 computer acts as • Intersection repeater node • Collect timing and status from other computers • Generates GUI for public • Controls parameters of processes on other computers

  4. Online Simulator Demonstration • AVI videos on loop • Demonstrate the OSU online wireless simulator on demand • Execute on a laptop (OSU will provide) • Connected to KVM switch in order to share large panel display with main demonstration?

  5. Hardware Requirements • 3 PCs • 3 802.11b wireless cards • 3 OKI 5.8 GHz modems • Wired LAN ethernet ports • We will install Linux into existing windows 2000 partition • 1 Large Flat Panel Display • Small LCD panels for testing/debug • KVM Switch (4 port) • Wired network hub and cables • Cellular phones in Japan

  6. Exhibit Requirements • Posters • Online simulator • Demonstration • Field testing ? • Look and Feel • Logos • Match OKI displays • Exhibitor badges

  7. Personnel and Schedule • Personnel • Keith Redmill • Umit Ozguner • Eylem Ekici • ? • Schedule • Arrive in Japan (Saturday Oct 16 ?) • Prepare PCs and demonstration (Sunday, Monday) • Exhibit hall open Tuesday – Sunday (Oct 19-24) • OSU personnel manning booth at all times?

  8. OKI Project Phase 2August, 2004 Test Plan Department of Electrical and Computer Engineering The Ohio State University 2 August 2004

  9. Locations • Open area • Large north-campus parking lot • Lane and Kenny Road intersection (interference unlikely, line of sight) • Multipath area (other signals likely) • Downtown Columbus • Campus (Neil and 18th) • Trees • SR315 or residential street • Columbus Metroparks • Tunnel • Airport taxiway underpass • Pedestrian tunnel (with radio on a cart?)

  10. Trees: SR315

  11. Trees: Whetstone Park

  12. Trees: Griggs Reservoir

  13. Trees: Blendon Woods

  14. Trees: Sharon Woods

  15. Trees: Highbanks Park

  16. Tunnel: Columbus Airport

  17. Tunnel: Columbus Airport

  18. 802.11b Testing: Capabilities • Transmit (udp) and receive packets in monitor mode (includes packets with received errors) • Control transmit bit rate and channel • Control transmit power (maybe, do we care?) • Control receiver RSSI cutoff (checking) • For each packet received • Signal strength (uncalibrated, linear, converts to dbm) • Noise (identify what this is) • BER (appropriate test patterns?) • Packet error rate (test patterns?) • GPS position information

  19. 802.11b Testing: Experiments • Use same test sites as OKI radio tests • Transmit test packet every 1 second • Experiment matrix • Vehicle speed (static, 15 mph, 30 mph, 45 mph, 60 mph) • Transmit packet length (16, 64, 256 bytes) • Packet contents test patterns (BER patterns) • Bit rate (1,2, 5.5, 11 Mbits) • Traffic conditions • Transmit power (?) • Network traffic loading (future)
