These resources are aimed at improving traffic safety and providing comfort to drivers and passengers. The resources use applications that have to meet high reliability and delay constraints. However, to implement these applications, VANET relies on IEEE802.11p medium access control (MAC) protocol. Many approaches have been proposed in the literature to enhance the efficiency of this protocol but they have encountered some challenges including access and merging collisions. In this work, we propose a novel access method for the broadcast of safety messages in IEEE802.11p of VANETs witch overcomes these challenges. Based on vehicles speed and knowledge of context information included in the beacon, the reuse of time slots is maximized by maximizing the number of transmissions scheduled in the same slot. The simulation results show that our protocol satisfies the requirements of safety applications and uses the wireless channel much more effectively than the default one defined in IEEE 802.11p.
