A Simulation Framework for Evaluating the QoS and QoE of TCP-based Streaming in an LTE Network

TCP-based streaming has garnered much research interest in the past few years. Yet it still remains difficult to evaluate the performance of such streaming approaches in mobile networks. In the past, this could be be partly attributed to the scarce availability of mobile network simulators but this circumstance has changed. Nevertheless, there are many open issues and challenges in video delivery over mobile networks.Inspired by the lack of tools for assessing video streaming QoS and QoE, we provide a streaming framework on top of one of the existing mobile network simulators. The framework is configurable and extensible enough to be able to be employed for many mobile and other network scenarios. The provided scenarios and example playback strategies are put to the test in some initial experiments. In these, a negative impact of mobility on the playback of a streaming video could already be revealed.
