Vehicular Ad hoc
Networks (VANET) is one of the most challenging research areas in the field of
Mobile Ad Hoc Networks. In this research, we propose a protocol called Contention
Based Broadcasting (CBB) protocol for increasing the emergency message
reception and performance, the emergency message will be broadcasted in multi-hop
fashion, and the multi-hop forwarders will be selected before the original
message is sent. This protocol will enable the emergency information to be propagated
for longer distances to warn away vehicles about the danger before reaching it.
