An Implementation of the DCF-MAC protocol based VANET

VANET (Vehicular Ad Hoc Network), a rapidly expanding wireless network using multiple routing systems to provide vehicle network connectivity Interconnection between vehicles is rapidly changing because of the frequent movement of VANETs. This frequently results in network topologies, resulting in path errors on these networks. Furthermore, the movement-induced track failure problem is a key priority in VANET to provide efficient network access to vehicles with an optimal QoS without disrupting service. This paper has randomly roamed the performance of various ad hoc mobile node routing protocols that have not been reported in previous studies of IEEE 802.11g VANET based on OFDM and that have a high data rate of 54 Mbps. This work showed the implementation of the DCF-MAC protocol to load VoIP traffic with OPNET Modeler 14.5.
