Future systems are likely to require both small nodes and a high density
of deployment, making efficiency and adaptability crucial to further
development,
says Professor Anders Rydberg.
Although a relatively young technology, the potential of
Wireless Sensor Networks is encouraging intense researchfocus.

Wireless sensors need to be..
To work SuccessfullyTo work Successfully
INTELLIGENT
Capable of operating inHarsh conditions
Low Powerconsumption
As sensors become smallerthe area available for theantenna is reduced.
Numerous innovative
integrated antena designshave been presented as pertheir uses and specifications.

Research efforts worldwide spandiverse areas, including new materials
such as nanotubes and nanofibers,miniaturization of electronics throughnanotechnology, or integration of severalsensors in artificial noses.
Growing concern worldwide forair pollution,biological threatsand security issues has led to anincreasing demand for sensors inmultiple application areas, thus
calling for a fast development ofsmall, reliable, inexpensivesensors which can be easilyintegrated in various devices andequipments.

What CAN be done!
Sense the changes in Environment and using those data tointerpret the conditions and problems prior.
Checking the sources and elements regularly to maintain thoseas per standards.
Change in ICE level of HIMALAYA affects whole INDIA.Imbalance in one chemical changes others itself.Weather and Climate is connected globally as well as locally.
TO See this and go deeper.

All of these involves a careful system design, since
requirements are very strict. battery life-timemaximization, robustness, recovery strategies, networkflexibility and reconfigurability.
"Very complete and insightful"
Eeelco de Jong, Director Sales and Marketing, Ambient Systems
Hope Continues as said for Wireless Sensor Network.
