Abstract:
The efficient broadcast of messages in Vehicular Ad-hoc Network (VANET) still faces many challenges in current research. In this paper, we are interested in multi-hop broadcast communication for neighborhood discovery applications which increase driver visibility. These applications need to send information with a high rate causing congestion in the network. To avoid this congestion, we propose a new broadcasting scheme consisting in favoring the information of the closest vehicles in a high vehicular density context. Therefore, we introduce the concept of message energy, which generalizes the typical time-to-live value. Our proposal is evaluated and compared with several existing broadcasting schemas using a network simulator. The results show an improvement in neighbor discovery in a congestion context.
