Abstract
To propagate emergency messages including vehicle accident, traffic congestion, environmental information at the highway driving is very crucial to provide safety attention to the follower drivers and passengers at the Vehicular Ad-Hoc Network (VANET). We design simple and easy implementable broadcasting scheme, SLBP(SNR based Linear Back-Off Protocol) which selects transmission sequence as based on received SNR(Signal Noise Ratio) value and linearly back-off at each receiver node inside same propagation range under not having priori neighbor’s information. We focus on the messages transmission delay, propagation distance and broadcasting storm size as varying the Wi-Fi equipment penetration rate on vehicles to estimate a deploy scenario of emergency propagation service. We examine proposed scheme by ns-3 simulation. NS-3 Simulation results show that the proposed SLBP scheme is less transmission packet sending to reach destination than simple broadcast flooding algorithm. Also simulation shows severe transmission delay under the condition of less 30% Wi-Fi equipment penetration rate both general broadcasting and SLBP scheme.
