This brief focuses on medium access control (MAC) in vehicular ad hoc
networks (VANETs), and presents VeMAC, a novel MAC scheme based on
distributed time division multiple access (TDMA) for VANETs. The
performance of VeMAC is evaluated via mathematical analysis and computer
simulations in comparison with other existing MAC protocols, including
the IEEE 802.11p standard. This brief aims at proposing TDMA as a
suitable MAC scheme for VANETs, which can support the quality-of-service
requirements of high priority VANET applications.
