The use of communication technologies to increase road safety is rising within
the automobile world. Many entities cooperate to find the best solution to add safety services
relying on vehicle to vehicle communication systems (V2V) and among vehicles and the
infrastructure (V2I) located on the roadside. However due the relatively low vehicle renewal
rate and economy restrictions a large transitory period is expected to happen. Safety services,
such as collision or emergency electronic brake lights have delay-critical requirements. This
work-in-progress paper (WiP) proposes a WAVE (Wireless Access for Vehicular Environment)
based architecture and a MAC protocol where Road Side Units (RSUs) play a central role in
scheduling vehicles safety message transmission with guaranteed bounded delay.
