Service exchanges between Deployment Sites
The interoperability provided by AIoTES allows the exchange of devices and services
between different DS that may use different platforms and data models without
the need to modify the existing applications. Legacy native applications, typically
platform-specific, can be used with a different platform thanks to the syntactic
and semantic translations performed by the SIL. This way, services and applications can be exchanged between different DS without increasing considerably the
complexity of the system. Thus, the DSs have incorporated new services and applications developed in a different one. Some examples of such exchanges are the
following:
Bed sensor exchange
The DS of WoQuaz (Germany) has a native universAAL application that receives
data from different sources, one of them being a bed sensor that provides presence
information of a user, which is very valuable for detecting in a non-invasive way
situations that may require the attention of caregivers (such as unusual long-time
stays or lack of presence at night). They are interested in using a different sensor
because their current option is expensive and not very reactive. The DS of Isére
(France) has a different application that receives data from a bed sensor from a
different vendor, but it is developed on sensiNact. Using the SIL to translate the data
from sensiNact to universAAL, the first DS has been able to incorporate the bed
sensor of the second DS without making changes in their application or having to
develop a new driver. In the implemented solution, the new bed sensor is managed
by sensiNact and a virtual representation of the device is created in universAAL
to provide data to the native universAAL application. The SIL translates the bed
sensor data in real time and updates the virtual sensor. This way, the application can
make use of the bed sensor data, together with the data coming from other devices
connected to universAAL.
Moreover, the DS of Isére can make use of the services developed in the DS of
WoQuaz, such as presence detection in the bed and behavior patterns analysis and
alerts based on the data obtained from the bed sensor (Fig. 4).
Health monitoring services exchange between Galicia and Greece
The DS of Galicia (Spain) offers health monitoring services developed on top of
SOFIA2. The DS of Greece has a different set of health monitoring services, which are
based on universAAL. Thanks to the semantic interoperability provided by AIoTES,
these services can be used in both DS (see Fig. 5). For example, a SOFIA2 native
service can use data from devices connected to universAAL without the need to
