There has been increasing interest in the use of context
awareness, as a technique for designing architectures dedicated to
smart spaces in order to adapt and produce suitable services according
to user needs. In recent years, various architectures have been
developed to support context-aware systems. The major challenge with
these systems is decomposing the entire architecture into smaller,
modular components that facilitate the comprehension and modification
of the architecture. In this article, we propose the model view
controller adapter (MVCA) architecture, derived from the
model-view-controller pattern, which is modular, flexible, and capable
of adapting services autonomously on behalf of users. The main concept
of MVCA architecture is that it decomposes the overall functionalities
into modular components with high cohesion and low coupling, which
facilitates reusability and maintainability of the system. The MVCA
architecture is essentially composed of four components that are
responsible for sensing and managing the environmental context in order
to adapt and produce services proactively according to user needs. To
demonstrate our architecture, we present a scenario-based simulation of
MVCA architecture using the Java Agent Development Framework platform.
