Description
Summary: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.
