The federation of critical infrastructure information via publish-subscribe enabled multisensor data fusion

The art and science of multisensor data fusion is the emerging foundation for the development of next generation network-centric decision support systems, including critical infrastructure protection. These challenging technical objectives require the cooperative signal processing of a federation of critical infrastructures. Publish-subscribe architectures provide process-to-process messaging infrastructures that enable a communications framework for the distribution and delivery of information between sensor fusion processes. In this paper we discuss high level service-oriented architectural issues for critical infrastructure multisensor data fusion including event notification services, wide area network topology, and the publish-subscribe subscription language.
