It is becoming more and more popular to share videos among multiple users. However, sharing video in traditional cellular networks will incur high expenses. Device-to-device (D2D) communication is one of the crucial technologies in the fifth-generation network, and it enables the devices to transmit data directly without the relay of base stations. This paper proposes a network-coding-based video distribution scheme for the D2D communication environment. The proposed scheme applies the network coding technology in the H.264 video transmission, which can protect crucial information of the video. This scheme enables the receivers to decode the original video with a high probability, especially in the networks with interferences. Both the simulation results and the actual experimental results show that using network coding technology in video transmission can improve the quality of the received video. Compared with the traditional scheme, the successful decoding rate of the proposed scheme is increased by \(46\%\) in our experimental settings.

网络编码可在多跳设备间通信中可靠地分发视频

在多个用户之间共享视频变得越来越流行。但是,在传统的蜂窝网络中共享视频会产生高昂的费用。设备到设备(D2D)通信是第五代网络中的关键技术之一,它使设备无需基站中继即可直接传输数据。本文提出了一种用于D2D通信环境的基于网络编码的视频分发方案。该方案将网络编码技术应用于H.264视频传输中,可以保护视频的关键信息。这种方案使接收器能够以高概率解码原始视频,尤其是在存在干扰的网络中。仿真结果和实际实验结果均表明,在视频传输中使用网络编码技术可以提高接收视频的质量。与传统方案相比,该方案的成功解码率提高了\(46 \%\)在我们的实验设置中。
