EVALUATION OF MAC IN VEHICULAR NETWORKS

Vehicular Ad hoc Network (VANET), a subclass of Mobile Ad hoc Network (MANET), is an important one for the intelligent transportation system (ITS).VANET, used to provide communication among vehicles and between vehicles to RSU. These networks have the potential to increase safety and provide many services to drivers and the passengers. VANET has the name as network on the wheel (NOW). Medium Access Control (MAC) is designed to send information from source to destination .We use VER-MAC to send data with reliability and energy efficiency. VER-MAC and IEEE 802.11p are the two standards used in VANETs. In this paper we compare the performance of VER-MAC and IEEE 802.11p standards in terms of two factors i.e. Packet Delivery Ratio (PDR) and the delay of emergency packets. The performance is mainly analyzed using ns-2 simulator.
