In this paper, we illustrate the design of a cross layered MAC and routing solution for supporting the fast propagation of broadcast messages at intersections in a vehicular ad hoc network (VANET). One of the fundamental services in VANET is broadcasting, that is a challenging task due to different road topologies and network conditions. One of its challenges is broadcasting at intersections, because vehicles in different roads constituting an intersections can affect on broadcast process of other roads, message may not be propagated in some directions. In this paper we propose a cross layered method that by classifying vehicles based on their location and the road they move in, solves this problem. Our method is simulated in NS2, and simulation results show our cross layered method is better than method based on IEEE 802.11.
