dc.description.abstract | Panoramic virtual reality video (PVRV) is becoming increasingly popular since it offers a true immersive experience. However, the ultra-high resolution of PVRV requires significant bandwidth and ultra-low latency for PVRV streaming, something that makes challenging the extension of this application to mobile networks. Besides bandwidth, the frequent perspective viewport rendering induces a heavy computational load on battery-constrained mobile devices. To attack these problems jointly, this paper proposes a PVRV streaming system that is designed for modern multiconnectivity-based millimeter wave (mmWave) cellular networks in conjunction with mobile edge computing (MEC). First, mmWave is deployed to support the high bandwidth needs of PVRV streaming. Next, the multiple mmWave links that tend to suffer from outages are coupled with a sub-6 GHz link to ensure disruption-free wireless communication. With the help of an MEC server, the tradeoff among link adaptation, transcoding-based chunk quality adaptation, and viewport rendering offloading is sought to improve the wireless bandwidth utilization and mobile device's energy efficiency. Simulation results show that the proposed scheme can improve the streaming performance in both energy efficiency and the quality of received viewport over the state-of-the-art schemes. © 1999-2012 IEEE. | en |
