Abstract
Vehicular Ad hoc Networks (VANETs) are new network environment for intelligent transportation systems. Many of applications in VANETs are based on dissemination of information, so broadcasting is one of the fundamental services in these networks. Broadcasting in VANET is a challenging task since these networks often lack continuous end-to-end connectivity and also have different road topologies. In this paper we present a broadcast method that improves the reception rates of broadcast messages by overcoming problem of connectivity gaps and omitting unreliability that occurs at intersections. We have simulated our method in NS2, simulation results show our method delivers message to most of vehicles by assuring propagating message in all roads and passing connectivity gaps.
