In Vehicular Ad hoc NETworks (VANETs), data dissemination is a challenging task. There are number of techniques, types and protocols available for disseminating the data but in order to preserve limited bandwidth and to disseminate maximum data over networks makes it more challenging. There are broadcasting, multicasting and geo-casting based protocols. Multicasting based protocols are found to be best for conserving the bandwidth. One such protocol named Bandwidth Efficient Acknowledgment-based Multicasting protocol (BEAM) exists that improves the performance of vehicular ad hoc networks by reducing the number of in-network message transactions and thereby efficiently utilizing the bandwidth during an emergency situation.
