Abstract

This paper proposes an implementation of systematic Raptor code in an ad hoc V2V (vehicular-to-vehicular) environment for post-crash safety broadcast. This is to address the latency problem caused by use of repetition code in a high speed vehicular environment for time-sensitive safety applications. The highly dynamic topology and challenging RF behavior of vehicular networks necessitate the use of a robust error control mechanism even with the use of spatial diversity techniques such as STBC-MIMO scheme. A cross-layer simulator model is used to evaluate the delay performance of Raptor codes against a low complexity repetition code. The numerical analysis demonstrates that the end-to-end delay performance is significantly reduced when Raptor codes are used, especially at higher distances from the source node. This is true in the case of single antenna as well as multiple antenna schemes.
