TSSG MSc by Research student Mohamed Adel Mahmoud recently presented a paper entitled “Online Estimation of VoIP Quality-of-Experience via Network Emulation” at the 24th IET Irish Signals and Systems Conference (ISSC 2013) in Letterkenny, Ireland. The paper was written by Mohamed, his supervisor Dr Brendan Jennings and collaborators from the Hamilton Institute in NUI Maynooth and the IBM Dublin Software Lab. The work is an output from a joint project between researchers in the FAME research cluster and IBM that is addressing the assessment and improvement of voice and video Quality-of-Experience (QoE) perceived by users of enterprise communications systems. The paper describes a novel testing framework that can provide online estimates of audio and video call quality on network paths, without requiring either end-user involvement or prior availability of audio/video sequences or network traces.
