Abstract Delay sensitive safety applications demand an efficient, quick, and reliable broadcast service. The existing D-TDMA MAC protocols may not be able to achieve the required QoS if the source node rebroadcasts the packet. Hence, it is necessary for the D-TDMA MAC to have a makeup strategy that provides a quick and reliable one-hop broadcast service specifically to satisfy the strict QoS requirements of the delay sensitive safety applications in VANETs. In this chapter, we present node cooperation based makeup transmission framework for D-TDMA MAC in VANETs, referred to as cooperative relay broadcasting (CRB). In CRB, nodes with packet from a source node rebroadcast the packet before it expires, making it suitable for delay sensitive safety applications with strict QoS requirements.
