Multiple-Source Streaming over Remote Radio Light Head: a pragmatic, efficient and reliable video streaming system for 5G intra-building use cases

The 5G Internet Radio-Light (IoRL) project aims to provide reliable intra-building wireless networks by using visible light and millimeter wave parts of the electromagnetic spectrum in addition with existing WLAN networks. One key aspect of the project is to provide reliable high-quality video streaming, which is difficult to do using state-of-the-art single-path video streaming systems in case of wireless network failure. By taking advantage of the plural network paths available by design in the IoRL architecture, we propose Multiple-Source Streaming over Remote Radio Light Head (MSS/RRLH), a DASH-compliant end-to-end multiple-path streaming system increasing both the reliability and the Quality of Experience (QoE) of the streaming sessions. The solution has been experimented and evaluated in the IoRL context and shows a significant decrease of stalling events while maintaining a low end-to-end delay for live streaming sessions.
