Beacon-less broadcast protocol for Vehicular Ad hoc Networks

This paper proposes a new vehicular broadcast protocol that can operate in dense as well as in sparse highway traffic scenarios. BL-CAST is a low overhead multi-hop broadcast protocol that does not rely on periodic exchange of hello messages. The performance of the proposed scheme was compared with DV-CAST. Simulation results showed that the performance of the proposed BL-CAST protocol is better than DV-CAST in terms of end-to-end packet delay and packet delivery ratio.
