论文摘要
虚拟现实（VR）随着多种在教育，医疗保健，娱乐等方面的应用而变得越来越普遍，以提高用户的移动性，并降低VR Head安装显示器（HMDS）的能源消耗和生产成本，带有边缘计算的无线VR一直是行业和学术界的重点。但是，将大型VR应用程序的大型视频帧及其严格的服务质量（QoS）要求对无线网络进行了要求需要在不同网络层之间进行创新和优化。为了开发有效的体系结构，协议和调度机制，需要各种类型的VR应用程序的流量特征。在本文中，我们首先计算理想VR体验以及流行的VR HMD的理论吞吐量要求。然后，我们使用启用边缘的Wi-Fi网络检查一组VR应用程序的流量特征。我们的结果揭示了有趣的发现，这些发现可以在开发新的优化，协议，访问机制和调度算法中考虑。
Virtual reality (VR) is becoming prevalent with a plethora of applications in education, healthcare, entertainment, etc. To increase the user mobility, and to reduce the energy consumption and production cost of VR head mounted displays (HMDs), wireless VR with edge-computing has been the focus of both industry and academia. However, transferring large video frames of VR applications with their stringent Quality of Service (QoS) requirements over wireless network requires innovations and optimizations across different network layers. In order to develop efficient architectures, protocols and scheduling mechanisms, the traffic characteristics of various types of VR applications are required. In this paper, we first compute the theoretical throughput requirements of an ideal VR experience as well as a popular VR HMD. We then examine the traffic characteristics of a set of VR applications using an edge-enabled Wi-Fi network. Our results reveal interesting findings that can be considered in developing new optimizations, protocols, access mechanisms and scheduling algorithms.
