Massive video multicasting in cellular networks using network coded cooperative communication

Abstract

The sharp increase in the video traffic and hand-held devices in the last decade warrant for new paradigms of applications including massive video multicasting, such as in the football stadiums, or concert halls where multiple angles of the live feed could be multicasted to the users' smart phones or tablets. However, the current state-of-the-art cellular solution is simply individually unicast the video stream to each node, which is extremely resource-inefficient. In this demo, we show how we perform reliable massive video multicasting over standard LTE links by combining the principle of cooperative networking and Random Linear Network Coding. We offload the majority of the traffic from LTE onto Wifi multicasts, thus increasing the efficiency of the LTE channel usage by multiple orders of magnitude. This demo has been demonstrated at the Mobile World Congress 2017 as a part of Nokia's booth to demonstrate the 5G stadium experience.
