摘要

在车载自组织网络(VANET)中，流行的视频传输服务可以为人们提供实时交通信息、实时新闻甚至高清电影，可以辅助人们在道路上驾驶，增强驾驶体验。本文提出了一种基于动态规划的高速公路VANET长期演进(LTE)网络可扩展视频流资源分配算法。我们通过使用小组图片(GOP)大小的可扩展视频编码(SVC)编码器和有效的信噪比(SINR)估计器来管理车辆的移动性。我们还采用了自适应的GOP接收窗口，提高了资源利用效率和视频质量。仿真结果验证了该算法的有效性。

Resource allocation for scalable video streaming in highway VANET

In vehicular ad-hoc network (VANET), the popular video transmission service can serve people with live traffic information, real-time news or even high-definition movies, which can assist people to drive on the road and enhance their driving experience. In this paper, we propose a dynamic programming based algorithm for the resource allocation problem of scalable video streaming through long term evolution (LTE) networks in highway VANET. We manage vehicular mobility by using small group of pictures (GOP) sized scalable video coding (SVC) encoder and valid signal-to-interference-and-noise ratio (SINR) estimator. We also adopt adaptive receive window of GOP to enhance the resource utilization efficiency as well as video quality. The simulation results demonstrate the efficiency of the proposed algorithm.
