In this paper, we propose a novel scheme for broadcasting non-urgent information in vehicular ad hoc networks (VANETs). The scheme, called low-overhead aggregated broadcast (LOA-CAST), aggregates information from different sources on a road and forwards it periodically. By aggregating the information from different sources and periodically propagating the message, it reduces the overall signaling overhead and dynamically adjusts the propagation distance of information according to the source density. We use analysis to evaluate the behavior of LOA-CAST in the presence of malicious/malfunctioning nodes. The results show that LOA-CAST can still function well and control the overall overhead if such nodes exist. Moreover, the results of simulations demonstrate that LOA-CAST incurs a reasonable overhead while propagating information efficiently.
