Focus of Project / Need and Industrial Relevance
(1 slide)

• Underwater Environment is challenging
• - too many variables/unknowns
• - temporal and spatial variations!
• Performance of UW deploymentsprotocols
• untested (currently)!
• ? need for good software
• analysis tools
• pre-deployment to
• mitigate risk!

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

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

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

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

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

8
Expected Impacts (1 slide)

• Mitigate risk !
• Essential component of continual
• planning and refinement!
