Résumé:
VANETs use many wireless communication techniques to improve driver’s safety and transportation efficiency. Therefore, the design of a good
broadcasting protocol that performs well in all criteria
in order to avoid storm problem, remains the most
paramount task. The thriving chore is how to maximize reachability while minimizing saved rebroadcast
and end to end delay. Most of prior work maximizes
reachability or minimizes the delay, but not both. In
This paper, a novel method was proposed to calculate
the waiting time of the counter-based and probabilitybased schemes, based on the speed of the vehicle, to
assess the congestion level of the network. Simulation
results through ns2 using 802.11P show that the new
method give better performances using different mobility scenaios (Grid and highway Map).
