Net-centric information spaces have become a necessary concept to support information exchange for tactical
warfighting missions using a publish-subscribe-query paradigm. To support dynamic, mission-critical and
time-critical operations, information spaces require quality of service (QoS)-enabled dissemination (QED)
of information. This paper describes the results of research we are conducting to provide QED information
exchange in tactical environments. We have developed a prototype QoS-enabled publish-subscribe-query
information broker that provides timely delivery of information needed by tactical warfighters in mobile
scenarios with time-critical emergent targets. This broker enables tailoring and prioritizing of information
based on mission needs and responds rapidly to priority shifts and unfolding situations. This paper describes
the QED architecture, prototype implementation, testing infrastructure, and empirical evaluations we have
conducted based on our prototype.
