We present a list of requirements that need to be

addressed by an infrastructure for information fusion where

applications have real-time requirements. The requirements are

grouped into configuration requirements, temporal requirements,

and robustness requirements. We show how the functionality of

a distributed active real-time database system (DARTDBS) can

meet many of the given requirements, and therefore, argue that

it is suitable for use in an information-fusion infrastructure with

real-time requirements. The design of a particular DARTDBS,

the DeeDS architecture and prototype, is presented as proof

of concept. A comparison with some alternative infrastructures

is briefly discussed. We describe a small distributed real-time

simulation experiment using DeeDS as infrastructure, and discuss

open questions such as how to deal with uncertainty management

of information sources, recovery of information fusion nodes, and

harmonizing data structures from different information sources.
