在移动的无线网络中广泛使用向多个用户广播诸如视频的流行数据内容。我们考虑一组移动的用户，他们彼此接近，对相同的视频或云服务感兴趣。在这种情况下，用户能够使用设备到设备（D2D）连接，例如，WiFi或蓝牙，以合作的方式获取视频。在本文中，我们考虑D2D辅助无线网络编码视频广播问题的用户与多个接口，以最大限度地减少传输时隙的数量。为了获得所有需要的视频，用户可以同时根据蜂窝链路和本地协作D2D链路接收编码分组。我们分析了两种不同接收机模型下的传输时隙数的上界和下界。在第一种模型中，接收器只是丢弃不能立即解码的编码数据包，我们提出了一种基于图中团划分的联合广播和D2D编码解决方案。在第二个模型中，接收器可以缓冲所有接收到的编码数据包，并解码时，收到足够的数据包，我们提出了一个最佳的解决方案，使用整数线性规划（ILP）制定，我们还提出了一个有效的启发式编码解决方案的基础上随机线性编码。仿真结果表明，所提出的传输策略可以显着减少传输时隙的数量在大多数情况下，这是一个重要的性能指标，在无线视频传输。
Broadcasting popular data content such as videos to multiple users is widely used in mobile wireless networks. We consider a group of mobile users, within proximity of each other, who are interested in the same video or cloud services. In this scenario, users are able to use device-to-device (D2D) connections, e.g., WiFi or Bluetooth, to get the video in a cooperative way. In this paper we consider the D2D-assisted wireless network coded video broadcast problem for users with multiple interfaces to minimize the number of transmission slots. In order to obtain all needed videos, user can receive encoded packet according to cellular link and local cooperative D2D links simultaneously. We analyze the lower bound and upper bound of number of transmission slots under two different receiver models. In the first model, receiver just drop the encoded packet which cannot be decoded immediately, and we propose a joint broadcast and D2D encoding solution based on the clique partition in the graph. In the second model that receiver can buffer all received encoded packets and decode when enough packets are received, we propose an optimal solution using an integer linear programming (ILP) formulation, and we also propose an effective heuristic encoding solution based on random linear coding. Simulation results show that the proposed transmission strategy can significantly reduce the number of transmission slots in most cases, which is an important performance metric in wireless video delivery.
