Comparative performance evaluation of DSRC and Wi-Fi Direct in VANET




Wi-Fi Direct , AODV , DSDV , VANET ,
In this paper, we present a comprehensive study on the performance and behavior of AODV and DSDV routing protocols by using two standards which is the conventional DSRC and the latest Wi-Fi Direct. DSRC is a well-known technology being considered as the most promising wireless standard in VANET. On the contrary, as the latest wireless networking standard, the potential of Wi-Fi Direct technology should be concerned. We evaluated these standards using both routing protocols under realistic mobility model in order to analyze the QoS performance by using NS-2 and SUMO simulator. It is demonstrated via simulations that AODV routing protocol produces better results compared to DSDV routing protocol in both standards. It also can be concluded that DSRC is slightly better than Wi-Fi Direct standard. However based on QoS performance that has been obtained by a combination of AODV and Wi-Fi Direct standard, we can defer that Wi-Fi Direct is feasible to be used as an alternative standard since it has been considered as potential competitor of DSRC in VANET.
