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

uncertainty.
