Vehicular Network Simulation Results

• Mobility Study
• The mobility model affects the plausibility of
  the simulation results
• Relevant metrics are node density and
  inter-contact time
• Infrastructure Benefits
• Flat network gets easily congested
• Hybrid scheme improves performance

Campus Vehicular Testbed at UCLA C-VeT

• Will provide
• A platform to support car-to-car experiments in
  various traffic conditions and mobility patterns
• A shared virtualized environment to test new
  protocols and applications
• Remote access to C-VeT through web interface

• Control Channel Coverage Test
• Reliable channel to constantly monitor the
  network
• Remote access to the mobile nodes

• Mesh Network Infrastructure
• Extend connectivity
• Provide Internet Access

• Campus Demo connectivity via OLSR
• Constantly monitor
• Car Position
• Network Connectivity

• Real Experiment P2P file sharing
• Fixed Nodes placed at 4 corners of Eng IV
  Building at UCLA
• 2 Cars revolve around the building
• Each node is aquipped with a 802.11g MIMO card
  and running OLSR
• All Nodes download a 100MB file from 1 fixed node
