S3-RNC: A novel V2V transmission scheme for Mobile Content Distribution

Abstract

In this paper, we propose a novel V2V transmission scheme, namely S3-RNC (Shuffled Scattered Symbol-level Random Network Coding), for Mobile Content Distribution (MCD) between communication pairs traveling on opposite directions. To cope with the Doppler Effect caused by extremely high relative velocity, symbol-level random network coding (RNC) with shuffling (interleaving) and scattering is used in our proposed scheme. As the second step, receivers, moving together as a cluster, cooperatively relay their received S3-RNC coded blocks, in order to maximize the probability of successful decoding. Our simulation results show that S3-RNC improves throughput performance significantly in high mobility environment. By utilizing S3-RNC, consumer vehicular communication devices are able to provide a lot of useful information to vehicular users.
