5.1.3. Sensor networks
Enhancement of technology in the field of wireless has led to a fast development of
sensor network with robust, low-cost, low-power, and high-performance properties.
Sensor networks represent a pervasive system composed of numerous sensor nodes and,
installed in an environment, are able to remotely monitor and manage data coming
from sensor nodes. Commonly they are distributed on one or more of the following
networks: body network, in-room or in-car network, home or building network, or
outdoor network over a wide area. Wireless sensor networks enable the remote
monitoring and management of critical devices while providing data to enable more
informed decision-making, better control, and increased revenue opportunities.
In an AAL solution, a sensor network is always combined with reasoning and
actuator systems, in order to provide a full assistive solution. Several approaches might
be used to implement part or whole of the solution:
A single sensor connected to a reasoning service which might be connected to
other reasoning services for aggregation. Those reasoning service will pass on
the results to other interaction services and devices.
Appliances, consisting of a sensor, reasoning and actuator for feedback
implemented in a single device; such an appliance might pass on results to
other reasoning and feedback services for aggregation.
Wireless sensor networks are suitable to be developed both in the field of
consumer and industrial applications (Hirvonen, 2007). In AAL context they might be
used in the form of body area network or smart environment.
Body Area Network sensors and mobile device. Wireless body-area networks usually
include wearable sensors conceived as foot, arm, wrist computers or smart clothing. In
future most of these sensors might be also integrated directly in many personal mobile
devices, such as laptops, mobile phones, PDAs, mp3 players, tablet PCs and wrist
computers, that will communicate continuously with each other. Typical future visions
describe a network full of self-configurable sensor nodes conceived to provide
