Embedded everywhere, hundreds of tiny sensors detect activities
in the real world, generating data that is used to feed
different systems, keeping the users informed about the current
system state and supporting him in the decision of how to
actuate next. Sensor networking technology is being applied in
many environments and with multiple purposes: transportation and
logistics, for structural health monitoring, habitat monitoring,
precision agriculture, tourism, smart ambients, sports and
entertainment, between others. These sensor networks, composed
of low-cost, low-power miniaturized sensor nodes communicate
untethered across short distances to carry out their collective
task. For these sensor networks to work, sophisticated
architectures and efficient communication protocols must be
developed to allow large amount of nodes collect, process and
disseminate data. In this seminar the current state and future
deployment of WSNs and familiar technologies and applications
will be explored.
