QoS to QoE Mapping Function for Iptv Quality Assessement Based on Kohonen Map: A Pilot Study
Transport and Telecommunication, 2020 This paper deals with an analysis of Kohonen map usage possibility for real-time evaluation of end-user video quality perception. The Quality of Service framework (QoS) describes how the network impairments (network utilization or packet loss) influence ...

International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency (>$$ > $$ 500 ms) and inadequate coverage at high ...

On the complexity of QoS routing
Computer Communications, 2003 We present SAMCRA, an exact QoS routing algorithm that guarantees to find a feasible path if such a path exists. Because SAMCRA is an exact algorithm, its complexity also characterizes that of QoS routing in general. The complexity of SAMCRA is simulated in specific classes of graphs.
