MAGMA (Mobility And Group Management Architecture) explores a distributed infrastructure for QoS provisioning to mobile users and groups thereof, through multiple geographically dispersed service points. This architecture can prove highly valuable  to many modern networking technologies, ranging from wireless mesh networks (WMN) for broadband Internet access to IP multimedia subsystem (IMS) for beyond-3G converged cellular/IP networks.

The key requirements from MAGMA are adaptiveness (i.e., handling dynamic phenomena such as user mobility, flash crowds etc), and scalability (i.e., coping with millions of users through thousands of service points). We focus on vital algorithmic aspects of this framework, as well as on prototype implementations of our algorihtms in real systems.
