WSNs on the Road for Automobiles
Presentation, (March 2005)13th Wireless World Reseach Forum, Jeju Island, Korea.
Abstract
Wireless sensor networks (WSN) are a particular class of ad hoc networks
that attract more and more attention both in academia and industry.
The sensor nodes themselves are preferably cost-cheap and tiny consisting
of a) application specific sensors, b) a wireless transceiver, c)
a simple processor, and d) an energy unit which may be battery or
solar driven. Such sensor nodes are envisioned to be spread out over
a geographical area to form in a truly self-organising manner a multi-hop
network. Such a network may remain autonomous and local in nature,
but also obtain gateway connectivity to larger area networks. Services
provided by and within sensor networks may be pure data acquisition,
but also derived added value services such as local hazard information
broadcast. Potential applications for such a scenario can be found
in monitoring environmental data with the objective to understand
complex and geographical wide spread interdependencies of the nature.
Examples are the detection of fire in huge forest areas, the monitoring
of the road status (frosted, aquaplaning, oily, obstacle) at some
particular points like bridges or curves, or the incremental shift
of snow and rocks in the Alps. Within the IST-FP6 project Daidalos
we intend to use WSNs for the Automobile scenario.
