摘要
在本文中，我们提出了一种新的V2V传输方案，即S3-RNC (Shuffled Scattered Symbol-level Random Network Coding)，用于移动内容分发(MCD)。为了应对极高的相对速度所带来的多普勒效应，我们提出的方案采用了带洗牌(交织)和散射的符号级随机网络编码(RNC)。第二步，接收器作为一个集群一起移动，合作中继接收到的S3-RNC编码块，以最大限度地提高解码成功的概率。仿真结果表明，S3-RNC在高移动性环境下显著提高了吞吐量性能。通过利用S3-RNC，消费级车载通信设备能够为车载用户提供大量有用的信息。
S3-RNC: A novel V2V transmission scheme for Mobile Content Distribution
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.
