An Ontology for the Quality of Experience framework
Edson Gallo, Mario Siller, John Woods · 2007
Agents need a formal representation of knowledge. This is modelled in an ontology. We present a survey of ontologies in the area of QoS management. From the survey we identified that improvements can be done in the Ontology of the Quality of Experience framework. We believe that with the extension full QoS Management capabilities can be then supported in the context of Quality of Experience. We focus in the appropriate QoS mechanism selection, network monitoring and QoS adaptation. With the additional concepts and actions the QoE ontology meets three key requirements for a QoS ontology: (i) decide which QoS mechanisms is better to fits the user needs; (ii) perform QoS monitoring and detection of SLA violations; and (iii) carry out QoS adaptation. Two experimental scenarios are currently being conducted. In scenario 1 the original ontology is used whilst for scenario 2 the extended version is employed. An initial comparative analysis is performed.
