    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.

    Most promising application area for WSN due to the necessity of proving the agricultural

    production chain in terms of precision and quality.

    Precision Farming System hasfollowing parts :

    Sensing agriculture parameters.Identification of sensing locations anddata gathering.Transfer data from crop field to controlstation for decision making.

    Actuation and control decision basedon sensed data.

    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.
