A Dedicated Multi-Channel MAC Protocol Design for VANET with Adaptive Broadcasting

Vehicular wireless communication should be able to provide vehicles with reliable and efficient data transmissions for various applications, especially safety applications. We present a dedicated multi- channel MAC protocol that has an adaptive broadcasting mechanism, specifically designed to provide collision-free and delay-bounded transmissions for safety applications under various traffic conditions. Besides defining the implementation of this protocol, we conducted simulation evaluations showing that it has promising performance on critical statistics.
