Vehicular ad hoc networks (VANET) enable promising new possibilities to enhance traffic safety and efficiency. The vision of VANET is that vehicles communicate spontaneously, exchanging traffic-related information such as road conditions and hazardous situations. Traffic-related information can be disseminated via multi-hop routing, thus enabling the propagation of important information over longer distances. The major contribution of this paper is to propose Hi-CAST, a hybrid intelligent broadcast algorithm for alert message dissemination in VANET. We also propose various variants of Hi-CAST considering fading factors. To deliver alert messages effectively, Hi-CAST uses delay and probabilistic broadcast protocols in conjunction with token protocols. The performance of Hi-CAST is evaluated through simulation and compared with that of other alert message dissemination algorithms. From the simulation results, we know that our Hi-CAST is superior to Simple, p-Persistence and EDB algorithms. Also, we design Hi-CAST (best) hybrid algorithm which combines Hi-CAST (parabolic) and Hi-CAST (cubic).
