Even though the main motivation behind wireless access for vehicular environments was to support time-sensitive safety applications, typical Internet applications are also required to attract private investment that would help expand the network and reduce the cost of implementing the systems. It is well known that the Automatic Repeat reQuest scheme used in the current IEEE 802.11p standard is highly inefficient for vehicular applications. Therefore a raptor-coded decode-and-forward relaying scheme with an efficient feedback channel, named the ‘r-DF scheme’ for infrastructure-to-vehicle infotainment applications is proposed in this study. The scheme is evaluated using a multi-layered simulator combining a realistic IEEE 802.11p physical and MAC layer design considering the presence of interference in a highway and an urban scenario. The simulation shows that the scheme achieved up to double the average aggregate throughput and tens of decoding time improvements over the state-of-the-art.
