keeping track of electronic transactions - technologies such as services for
trusted data management: a networked environment where the security,
confidentiality and privacy of data can be trusted, for applications such as an
electronic notary;
to achieve trustworthy and dependable distributed systems solutions in the
area of autonomous computing are needed;
single sign-on for ease of use.
Power management and low power. Power management requirements differ across
the components, sensors and actuators in an environment like the home as well as on-
body sensors and actuators and wearable application hosting devices should be low
power or re-charging should be fit in the daily behaviour of the persons. Solutions that
can be applied are e.g. power transmission or energy scavenging at distance of up to 1
meter to recharge the battery for wearable or implanted devices without asking the
patient to do this, as it is too much to ask patients to perform this task regularly. Other
devices might have a power plug.
6.4. Interoperability
Since an AAL solution consists of several quite often independently developed systems
that come from multiple suppliers or providers, interoperability is an important issue
and relies on the use of standards.
The goal of AAL however is to come to interoperable systems that can work together
and from the view of the users presented as an integrated system that collects
information from different subsystems and can even reason about it to give adequate
responses to the user. To realize this, interoperability in the following areas are needed.
AAL is becoming increasingly dependent on electronic and communicating systems.
Until the last twenty years, most electric and electronic systems were self contained and
were not capable of easily communicating with one another; they did not need to.
Convergence of communication, systems, networks and services has changed this. In
most environments, multiple services and systems need to share resources and may
need to “know” about other systems and services and what resources or information
they can provide. Hence the importance of interoperability.
Interoperability is important in the digital home and increasingly also for mobile
situations. Within AAL we have already seen a number of dissimilar systems in the
home (the entertainment system, the telecommunication system, tele-monitoring
systems and often security systems and the PC Network). These operate independently
of one another although they may use one another's resources and already there is
significant convergence between these systems.
Convergence is driving systems to work together in an interoperable manner. Almost
all electrical devices use some form of electronic computation in their designs, and
because this implies the use of microprocessors and in general microprocessors now
have communication capabilities, this means that almost all electric devices in the
home and workplace, i.e. most domestic and commercial appliances, have a
communicating system as an integral part.
The physical area. This includes mechanical, electrical, frequency and magnetic
aspects. At this level CENELEC plays an important role.
