Improving Video Streaming Quality in 5G Enabled Vehicular Networks

Abstract

The 5G mobile communication technologies are the most prominent candidates for vehicular networks to support various types of applications. In this article, we describe several 5G technologies and how these technologies support various types of vehicular applications. Since high-quality video streaming over vehicular networks is one of the most popular on-road entertainment applications for passengers, this article discusses the challenges of video streaming over 5G enabled vehicular networks. To achieve better video streaming quality, we introduce a double-buffer system to mitigate the delay effect due to a vehicle's frequent handoffs among 5G small cells and the intermittent connection effect resulting from millimeter-wave propagation features. We also discuss potential future work on joint optimization of buffer space and bandwidth allocation for video streaming, and maintaining connectivity for real-time applications in 5G enabled vehicular networks.
