We introduce MaGMA, a Mobility and Group Management Architecture,
enabling real- time collaborative group applications such as
push-to-talk (PTT) for mobile user s. MaGMA provides, for the first
time, a comprehensive and scalable solution for group management,
seamless mobility, and quality-of-service (QoS). MaGMA is a
distributed IP-based architecture consisting of an overlay server
network deployed as part of the service infrastructure. MaGMA's
architecture consists of a collection of mobile group managers (MGMs),
which manage group membership and may also implement a multicast
overlay for data delivery. The architecture is very flexible, and can
co-exist with current as well as emerging wireless network
technologies. We see such services as essential components in
beyond-3G (B3G) networks. We propose two group management
approaches in the context of MaGMA. We devise protocols for both
approaches, evaluate both solutions using simulations, and validate
the results through mathematical analysis. Finally, we present a
proof-of-concept prototype implementation.
