AbstractMajority of vehicular safety applications such as collision avoidance and blind spot warnings require a limited delay for a message to be transmitted from the abnormal vehicle to the endangered vehicles to avert the occurrence of the accident. This paper proposed a Timely and Efficient Multihop Broadcast (TEMB) Scheme, which combines an adaptive forwarding strategy that depends on the estimated transmission range between moving vehicles on the road. The scheme further combines ARQ with an adaptive Forward Error Correction system to minimise the number of retransmissions while ensuring the reliability of message delivery to the intended recipient. Modifications on the IEEE802.11p data and acknowledgement (feedback) frames are presented. The scheme has been evaluated and compared with the Fast Broadcast scheme, the results have shown that the TEMB scheme has outperformed the Fast Broadcast scheme for reliable and timely message delivery among the moving vehicles on the motorway.
