Maintenance without Synchronization

Maintenance without Synchronization. Issue arises with short-listen problem associated with unsynchronized networks Instead of picking t from [0, t ], distribution is used over [ t/2, t ] What is meant by synchronization?. Evaluation in Multi-hop Networks.

Presentation Transcript

  1. Maintenance without Synchronization • Issue arises with short-listen problem associated with unsynchronized networks • Instead of picking t from [0, t], distribution is used over [t/2, t] • What is meant by synchronization?

  2. Evaluation in Multi-hop Networks • Results for TOSSIM-packet simulation • At higher densities, does not match TOSSIM-bit  why? • Higher density  hidden terminal problem

  3. Hidden Terminal Problem • Why not CSMA/CA? • No RTS/CTS

  4. Redundancy • Redundancy “portion of messages heard in an interval that were unnecessary communication” • Redundancy = - 1 • Perfect redundancy = 0 • Trickle redundancy grows logarithmically • Why?

  5. Thank You!
