  1. The Ad Hoc UAV Ground Network (AUGNet) Timothy X Brown Interdisciplinary Telecommunications Electrical and Computer Engineering University of Colorado Presented at the AIAA 3rd “Unmanned Unlimited” Technical ConferenceChicago September 21, 2004

University of Colorado Brian Argrow Cory Dixon Jack Elson Sheetalkumar Doshi Daniel Henkel Jesse Himmelstein Sushant Jadhav Gerald Jones Marc Kessler Jake Nelson Phillip Nies Bill Pisano Roshan-George Thekkekunnel Institute for Telecommunication Sciences John Ewan Fidelity-Comtech Joe Carey L3-Corporation Ken Davey Thanks to T.X Brown (http://ece.colorado.edu/~timxb)

  3. Unmanned Aerial Vehicles (UAVs) • Small (10kg) Low-Cost ($10k) UAVs • Swarming, flocking, cooperative missions • Military, scientific, commercial applications T.X Brown (http://ece.colorado.edu/~timxb)

  4. Ad Hoc Networks A C B Network Layer RelayingRobust Connectivity T.X Brown (http://ece.colorado.edu/~timxb)

  5. Ad hoc UAV-Ground Networks Scenario 1: increase ground node connectivity. NOC Scenario 2: increase UAV mission range. T.X Brown (http://ece.colorado.edu/~timxb)

  6. We are building AUGNet • COTS Radio Components • Small Low-Cost UAV • Full-Scale Test Bed. • Fixed nodes • Mobile ground nodes (vehicle/personnel carried) • Aerial vehicle mounted nodes Test bed is another paper T.X Brown (http://ece.colorado.edu/~timxb)

  7. AUGNet Hardware Strategy • Common hardware and software platform • COTS communication hardware • Open Source network software • Custom UAVs • Flexible and stable design T.X Brown (http://ece.colorado.edu/~timxb)

  8. Environmental Enclosure UAV Mounting 21cm 16cm Communication Hardware Common Hardware802.11b PCMCIA cardSoekris single board computer0.1-1W AmplifierGPS (for monitoring) 256MB CF “personality” T.X Brown (http://ece.colorado.edu/~timxb)

  9. Communication Software • Linux operating system • Click packet processing • Dynamic source routing • Self starting, automated • No long-term state • RAM file system • ROM personality • Robust T.X Brown (http://ece.colorado.edu/~timxb)

  10. Test Bed Table Mountain National Radio Quiet Zone Experimenting to show the effect of the UAV T.X Brown (http://ece.colorado.edu/~timxb)

  11. Delay • Delay ~10ms per hop • Have tested VoIP application. Works well up to 3 hops Fixed nodes separated by 1 – 5 hops T.X Brown (http://ece.colorado.edu/~timxb)

  12. Throughput • Ad hoc throughput > 100kbps up to 5 hops • UAV enables short cuts that preserve throughput T.X Brown (http://ece.colorado.edu/~timxb)

  13. Histogram Packet Loss in 20 sec Interval Range • UAV more than doubles the range • UAV performance more erratic: more maneuvering T.X Brown (http://ece.colorado.edu/~timxb)

  14. Node Mobility • Mobile nodes are not reliable relays • UAV helps bridge unreliable links Between fixed node groups Mobile Relay Within fixed node groups To/From Mobile Nodes T.X Brown (http://ece.colorado.edu/~timxb)

  15. Summary: • We are building COTS-based ad hoc networks on UAV, fixed, and mobile nodes. • Range: 1.2km Grnd-Grnd, 3 km UAV-Grnd • Low Delay, Good Throughput: Can do VoIP • UAV maneuvering affects performance T.X Brown (http://ece.colorado.edu/~timxb)

  16. Next Steps: • Coupling Plane Dynamics with Communication • UAV Flocking • Multi UAV operations Project website: augnet.colorado.edu T.X Brown (http://ece.colorado.edu/~timxb)
