  1. 2.

    Introduction •  VANET module: MOVE –  MObility model generator for

    VEhicular networks •  AODV+ –  use AODV for simulations of wired-cum-wireless scenarios
  2. 3.

    Motive •  Improve VANET performance –  Using APs in the

    city –  Fast & reliable Ethernet •  But “where are you?” –  If we don’t use Mobile IP… •  Implement AODV+ on both wired and wireless nodes
  3. 4.

    Experiment Design •  Car numbers –  9, 26, 32, 44,

    55, 65 •  AP numbers –  0, 4, 9(3x3), 16, 25, …, 100 •  Random traffic –  Using MOVE
  4. 5.

    Modification •  AODV+ does not work –  wired <--> wireless

    –  wireless -> wired -> wireless ? •  Alternative –  motionless cars act as APs

    Conclusion •  Too much water drowned the miller –  When

    mobility and density is low, AP counts •  Trade-off –  High transmission rate –  Extra routing table overhead
