Support et gestion de la qualité de service dans les réseaux mobiles

The objective of this PhD thesis is to develop architectures and mechanisms allowing the QoS provision to wireless network users. In the first part of this thesis, we elaborated two novel mechanisms for QoS support in wireless access networks. This support is addressed regarding to two different aspects and applied to two particular cases. The first mechanism we propose and evaluate, PRKF, is a new predictive scheme for radio resource allocation. It aims to reduce the handoff-dropping probability in cellular networks. Our second proposal, P3-DCF, aims to offer an effective QoS to the packets crossing IEEE 802.11 networks. In the second part of this thesis, we focus on designing and evaluating novel architectures for QoS management in wireless environments. We consider two separate environments. Firstly, we propose and evaluate a complete end-to-end QoS management framework for wireless Internet access. This framework considers the case of mobile users that access a DiffServ backbone throughout a P3-DCF-enabled access networks. Finally, a discussion on how to adapt the proposed management architecture to ad hoc networking environments is presented.
