TSSG MSc by Research studnt Mohamed Adel Mahmoud Mohamed recently presented a paper entitled “A Generic Algorithm for Mid-call Audio Codec Switching” at the 1st IFIP/IEEE International Workshop on QoE Centric Management (QCMan 2013) in Ghent, Belgium. 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. This paper presented an algorithm that performs in-call selection of the most appropriate audio codec given prevailing conditions on the network path between the end points of a voice call, taking into acound the QoE improvement that could be gained by switching codec and the negative impact of the switching process itself. Mohamed’s paper was one of three shortlisted for the best paper award at the workshop.
