Commercial and
economic drivers
Every economic sector will employ WSNs to improve
efficiencies, track and predict problems; industries
using WSNs will have a clear technological and
competitive advantage over non-users.
Many of the core technologies are already well
advanced - low power communications chipsets and
standards (ZigBee, Bluetooth, 802.11...) and others
are being developed; some demos are already being
realized (mainly in the USA using MOTES). These are
rapidly becoming validated and effective technologies
in need of a killer application.
Top Three Key
Technological Issues and Drivers
Issues
Development of novel sensor technologies, which are
commercially viable with sustainable competitive
advantage in the global market, a key example being
the integration of chemical sensors and biosensors
into WSN world.
Availability of low cost, low power energy efficient
design (consider rechargeable and battery-less/energy
harvesting operation as a goal), low bandwidth, long
distance/range (100s of m or order of Kms) wireless
communications.
Highly Integrated - Fully integrated sensor, signal
conditioning, processing and wireless interface on a
single die.
A global standard for automotive electronics and
applications to include 2 frequency options, possibly
more. The RF link should ideally be suited for energy
transmission.
Driver
Increasing impact of wireless communications on the
way we live
- this trend will continue and demand new
sources of information about many more aspects of our
lives.
“Ubiquitous
computing is roughly the opposite of virtual
reality. Where virtual reality puts people
inside a computer-generated world, ubiquitous
computing forces the computer to live out here
in the world with people.”.
