An Architectural Model for Situation Awareness in Ubiquitous Computing

One of the major research challenges of Ubiquitous Computing (UbiComp) is related to the need of the applications being aware of the situational context awareness, and when appropriate, respond to it. This paper presents an architecture for situation awareness, called EXEHDA-SA (Execution Environment for Highly Distributed Applications-Situation Awareness). We consider that the main contribution of this work is the architecture that supports acquisition, processing, and dissemination of contextual information, in a distributed way, independently of the application, in an autonomic perspective and rule-based. To assess the functionality of the EXEHDA-SA, we present a case study implemented in Didactic Laboratory of Seed Analysis (LDAS), at Faculty of Agronomy (FAEM), Federal University of Pelotas (UFPel).
