René Meier and Vinny Cahill, Location-aware event-based middleware: A paradigm for collaborative mobile applications?, 8th CaberNet Radicals Workshop, Ajaccio, Corsica, France, October, 2003
Existing research on event-based middleware for
mobile computing has mainly focused on supporting nomadic
applications using wireless data communication based on the
infrastructure network model. Relatively little work has been
done to accommodate collaborative applications that often use ad
This paper describes a novel kind of event-based middleware,
called STEAM, that has been designed for use in ad hoc
networks. STEAM differs from other event-based middleware in
that its architecture does not rely on the presence of any separate
infrastructure and event notification filters may be used to define
geographical areas within which event notifications are valid,
thereby bounding the propagation of these notifications. Such
proximity-based filtering represents a natural way to filter events
of interest in collaborative mobile applications.
