Introduction
• The VANET can be used for driver-vehicle
safety applications and non-safety applications.
• Moreover, the routing protocol has to be
efficient in this high mobility context where
topological changes are very frequent.
Introduction
• It uses techniques of micro simulations to
obtain realistic trajectories of vehicles on a
highway.

Dimensioning the hybrid network
• λ corresponds to the mean number of
vehicles per kilometre.
• we assume that the radio range of all
nodes is a ball of radius R.
• exp { λR }:The mean number of vehicles per
cluster
Dimensioning the hybrid network
Dimensioning the hybrid network
• We can guarantee with a probability of 1
− ε that a vehicle can reach an AP if P (C
≥ L) ≥ 1 − ε ,
