The vision of Ambient Intelligence (AmI) as a new paradigm for
supporting the mobile user in his daily activities is currently
entering the focus of European research efforts. A high degree of
autonomy on the part of the supporting software system is inherent
to this vision of omnipresent and continuously running services.
However, adequate concepts for creating respective infrastructures
that may operate autonomously and in a self-organized fashion are
still largely unexplored. We propose the Ad hoc Service Grid (ASG)
as a dedicated AmI infrastructure that may be deployed in an ad hoc
fashion at arbitrary medium-sized locations (shopping malls,
construction sites, trade fairs, etc.). In this paper, we give an
overview over our results thus far. We focus on the problems of
service placement, discovery and lookup, and data consistency within
an ASG environment and show how we have solved these problems with
new self-organizing and adaptive algorithms. These vital functions
are the basis for the realization of ASG systems and represent an
essential contribution to AmI research in general.
