The
emergence of applications operating independently of direct human control is
inevitable. Research on high-level models for this class of applications -- e.g.
on autonomous agents and distributed AI -- has revealed the shortcomings of
current architectures and middleware interaction paradigms. If we focus on
complex real-time systems made of embedded components, that evidence is even
more striking. Event models have shown to be quite promising in this arena, but
they often lack one or several of the following key points: seamless integration
with a programming model; adequate layer structure; and the provision of support
for non-functional attributes, such as timeliness or quality of service, or
security. This paper discusses infrastructural support to construct large-scale
proactive applications based on the use of real-time sentient objects, and is
specially devoted to the latter two points.
