WSN: A link between the sensory world and the digital world

Earliest: In 1994 DARPA funded research on ‘Low Power Wireless Integrated Micro sensor’

In 2003, Technology Review from MIT, listed WSN on the top, among 10 emerging technologies that would impact our future

• “A sensor network is a deployment of massive numbers of small, inexpensive, self-powered devices that can sense, compute, and communicate with other devices for the purpose of gathering local information to make global decisions about a physical environment”.

LANDSLIDE DETECTION

• Bases on research paper by Amrita University for landslide detection.

• Implemented at  Munnar, Idukki, Kerala, India.

• Collects data such as moisture, vibration and movement .

• Embedded 15 meters beneath the earth at different points.

HABITAT MONITORING

Great Duck Island Experiment• Leach's storm petrels spend much of

their lives out on the waters of the South Atlantic, heading north and to shore in the springtime to mate.

• Once on dry land, the male digs a shallow, narrow burrow, 2 to 6 centimeters below ground, 3 to 6 cm across, and anywhere from 30 cm to 2 meters long.

• Here the female will lay just one egg. Both parents will occasionally leave the nest to fly back out to deep waters to feed.

David Culler and his team at UC Berkeley have deployed since 2002 a network of more than 20 motes on the Great Duck Island to monitor the island’s habitat and the breeding habits of Leach Storm Petrels

• Passive infrared (PIR) sensors directly measure heat from the seabird

• Temperature/humidity sensors measure variations in ambient conditions resulting from prolonged occupancy

Sensors used

Extreme Scale Wireless Sensor Networking

• In December 2004, the OSU DARPA-NEST team headed by Anish Arora completed the first demonstration and experiments of ExScal.

• Demonstration covered an area 1.3km by 300m with about 1000 sensor nodes and around 200 backbone nodes

• One possible application: detection & classification of multiple intruder types over an extended perimeter.

FUTURE

‘Smart dust’ to explore planets:

Tiny “smart” devices that can be borne on thewind like dust particles could be carried in space probes to explore other planets, UK engineers say. The devices would consist of a computer chip covered by a plastic sheaththat can change shape when a voltage is applied, enabling it to be steered. Details were presented at the National Astronomy Meeting in Preston. John Barker, from the University of Glasgow, said the particles could use wireless networking to form swarms.
