Extended Abstract
This abstract summarizes the work which will be presented as a poster entitled ”A
Sensory Oriented Model for Monitoring Ubiquitous Environments”. It is concerned
with the development of a sensory-oriented model to monitor user’s environments. The
model supports a wide range of sensors and devices to be interconnected and managed
through a simple interface. Each sensor is represented by an intelligent module called
”virtual driver” that manages the device and interacts with other modules in a network-
like architecture. The gathered sensor data is fed to a local computer or to a remote
server through Internet connection for monitoring.
W3C XML Schema Language [1] [2] is used to describe the interactions. This al-
lows the use of well established standards, to guarantee the inter-operability, extensi-
bility and scalability of the model. Indeed new sensors can be easily plugged into the
system without necessarily rewriting major parts of the code, powerful configuration
files allow to simply add new information recipients or to listen to other modules. The
communication between the modules has been also standardized using W3C XSDs and
can thus easily be adapted to several programming languages. Another dimension of
the model is the interoperability between different technical worlds. Different modules
can be implemented using different platforms and in different programming languages;
this feature further increments the usability and decrements the developing costs as
we do not have to implement several versions for several platforms. Typically, at least
one module in the spider web must be considered as the decision maker; this module
interprets the data and sends the interpreted information to the next modules.
In order to have a validation of the model implementation work has been conducted
in the framework of a medical care scenario. Additionally two projects are under the
way, emphasizing the use of the model in other scenarios. One explores the use of the
model in an in-house temperature control, and the other one in a fire alarm system. Our
ongoing and future work covers three research thrusts. The first one concerns the exten-
sion of the system with a security mechanism. The second one concerns the integration
of the model in the CB-SEC framework [3]. Indeed the development of the model is part
of a framework called CB-SeC (Context Based Service Discovery and Composition),
whose aim is to develop a model for service discovery and composition in pervasive
environments based on context. The third one concerns the enhancement of the model
to take into account more features of the sensory information such as, imperfection and
