An Evaluation Mechanism for QoS Management in Wireless Systems

The evaluation of QoS requirements is one of the critical functions that span both the design and the run-time phases of QoS management. This paper presents an architecture for QoS evaluation and admission control, based on the modelling of both system behaviour and QoS requirements. Two aspects are considered. The first refers to QoS management, and to the component-based architecture for QoS evaluation. The second relates to the approach and its illustration by a case study, based on a personal area network. The proposed approach relies on the instantiation of models for representing both the behaviour and the QoS aspects of the system in terms of timed automata. The compatibility of the evaluation mechanism with architectures with a defined role for a QoS manager, such as ITSUMO, is also highlighted
