it involves off-board equipment which is also typi-
cally less stable. Third, once data sets become large
enough one can consider more sophisticated analy-
ses through data mining techniques, or by linking our
data repository with databases dealing with topics as
diverse as traffic flows, building schedules or disease
occurrences. Finally, within the larger context of sus-
tainability we cannot but consider the energy trade-
off of the technological developments we propose. In
particular, we need to assess the amount the power
our overall solution consumes for different numbers
of contributing and consulting users.
