| Research Abstract |
Vehicular ad hoc networks (VANETs) have been attracting interest in recent years for their potential uses in intelligent transport systems. In this research, we proposed a reliable and efficient multi-hop broadcast protocol which can be used to deliver emergency messages in VANETs. The proposed protocol selects relay nodes by employing a fuzzy logic to jointly consider inter-vehicle distance, vehicle movement and received signal strength. The protocol also uses an efficient retransmission mechanism to recover from packet losses. The proposed protocol was evaluated by using a real world vehicular ad hoc network. The experimental results showed that the proposed protocol can provide a high packet dissemination ratio, low message overhead and low end-to-end delay.
