Abstract. Context-aware applications use and manipulate context information to detect high-level situations, which are used to adapt application behavior. This paper discusses the specification of situations in context-aware applications and introduces a rule-based approach to detect situations. Situations are specified using a combination of UML class diagrams and OCL constraints. We support a wide range of situations, which can be composed of more elementary kinds of context. We discuss how to cope with distribution and to exploit it beneficially for context manipulation and situation detection. We employ a generic rule-based platform (DJess [2]) to support the derivation of situations in a distributed fashion.

“…The pioneering system Gaia [Román et al 2002] introduces the concept of active spaces, a middleware infrastructure enacting distributed active blackboard spaces, acting as the means for service interactions. Later on, a number of proposals have extended upon Gaia, to include additional functionalities and features for active spaces to enforce dynamic semantic pattern-matching for service composition and discovery [Fok et al 2009] or access to contextual information [Costa et al 2006]. Other related approaches include: Egospaces [Julien and Roman 2006], exploiting a network of tuple spaces to enable location-dependent interactions across components; LIME [Picco et al 1999], proposing tuples spaces that temporarily merge based on network proximity, to facilitate dynamic interactions and exchange of information across mobile devices; its extension, TeenyLime [Costa et al 2007] targeting sensor networks; and the already mentioned TOTA [Mamei and Zambonelli 2009].…”

To support and engineer the spatial coordination of distributed pervasive services, we propose a chemical-inspired model, which extends tuple spaces with the ability of evolving tuples mimicking chemical systems, i.e. in terms of reaction and diffusion rules that apply to tuples modulo semantic match. The suitability of this model is studied considering a self-adaptive display infrastructure providing nearby people with several visualisation services (advertisements, news, personal and social content). The key result of this paper is that general-purpose chemical reactions inspired by population dynamics can be used in pervasive applications to enact spatial computing patterns of competition and gradient-based interaction.
