VANETs are a form of mobile ad-hoc networks to provide communications among nearby vehicles and between vehicles and nearby fixed equipment. Safety applications like collision alert merge assistance, road condition warning, etc. requires messages to be propagated from the point of occurrence to the target vehicles with very low latency. DSRC is a two-way short-to-medium range wireless communication capability that permits very high data transmission critical in communications-based active safety applications. The previous paper which the authors taken into consideration is to develop analytical model for the reliability of a Dedicated Short-Range Communication (DSRC) Control CHannel (CCH) to handle safety applications in Vehicular Ad hoc NETworks (VANETs). In their paper, they enhance the conventional Dedicated Short-Range Communication (DSRC) for VANET safety applications.
