This paper introduces a framework for the adaptation of QoS in a wireless mobile environment (mob-QoS). A main feature of this framework is the ability to cope with inconsistencies created from mobility events (e.g. handoffs) in an end-to-end fashion. Adaptation in this framework is separated into (a) application and (b) network QoS adaptation. We define specific procedures for Mob-QoS changes (upgade and degrade) to better control the amount of QoS signalling and the required update completion time. We demonstrate the advantages of the proposed QoS adaptation framework through simulations.
