Abstract :
The main challenges in formulating efficient medium access control (MAC) protocols for vehicular ad-hoc networks (VANETs) are the fast mobility of vehicular nodes and hence, the high dynamicity of the network. VANETs present unique characteristics and hence, most MAC protocols for mobile ad-hoc networks (MANETs) might not be appropriate for VANETs. Research in the field of MAC protocols for VANETs has led to several novel ideas being proposed. This article reviews MAC protocols adaptable for VANETs and compares most recently proposed novel MAC protocols, which consider the 5.9 GHz or dedicated short range communications (DSRC) band. We attempt to demonstrate how three such proposed VANET MAC protocols have the potential to be combined to realize a MAC protocol that addresses the major requirements of VANETs, namely: efficient use of spectrum, minimization of packet delay, as well as authentication, security and prioritized delivery of safety messages.
