  1. Simulation Tools for Underwater Acoustic Network Analysis Sumit Roy Dept. of Electrical Eng. Fundamentals of Networking Lab U. Washington, Seattle roy@ee.washington.edu www.ee.washington.edu/research/funlab

  2. Focus of Project / Need and Industrial Relevance (1 slide) • Underwater Environment is challenging • - too many variables/unknowns • - temporal and spatial variations! • Performance of UW deployments+protocols • untested (currently)! •  need for good software • analysis tools • pre-deployment to • mitigate risk! Innovation through Partnerships

  3. Project Purpose and Goals (1 slide) • UW is a leader in UW channel modeling and simulation tools • Bell Hop: ray-tracing based accurate channel models • ns-3: network simulation engine for analysis of protocol stack [funded by NSF over 8 year period] Innovation through Partnerships

  4. Existing ns-3 UAN Simulation Library Supports AUV mobility models Includes PER and interference models Channel delivers prop. model data to PHY PHY uses PER and interference modules to compute SINR and RX success Current MAC models ALOHA with Random Backoff MAC Reservation Channel MAC protocol Net Device MAC PER PHY SINR Channel Propagation Model 4

  5. Primary Project Objectives (1 slide) NS3 UAN Future Work • Integrate new link packet error rate (PER) models [collaborate with UConn] • OFDM • Identify network topologies (industry defined) • Develop AUV mobility models (industry defined) • Implement new MAC protocols (industry recommendations) • APCAP [1] • Slotted FAMA [2] Innovation through Partnerships

  6. Approach & Methods (1 or 2 slides MAX) • Customize ns-3 solutions to partner needs - develop new modules within ns-3 - conduct full suite simulations - tech transfer and support MAC MAC Pkt, Mode, SINR PHY PHY Pkt, Mode, Rx Pwr, PDP Channel Src Mobility, Dest Mobility Rx Power, PDP Prop. Model Innovation through Partnerships

  7. Outcomes/Deliverables (1 slide) • Work with partners pre-deployment to provide initial predictive assessments • Integrate partner data (channel measurements, node mobility characteristics) into customized solutions • Provide recommendations for experiments, staging deployments Innovation through Partnerships

  8. Expected Impacts (1 slide) • Mitigate risk ! • Essential component of continual planning and refinement! Innovation through Partnerships
