Network Coding for Reliable Video Distribution in Device-to-Device Communications

It is becoming more and more popular to share video among multiple users. However, sharing video in traditional cellular networks will incur high expense. Device-to-Device (D2D) communication is one of the key technologies in the 5th generation(5G) networks, 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 D2D communication environment. In the scheme, the network coding technology is applied in the H.264 video transmission, which can also provide additional protection to key information of the video. This scheme enables the receivers to decode the original video with a high probability, especially in the networks with interferences. Simulation results show that the quality of video is improved after using network coding.
