2. INDRODUCTION
*A wireless sensor network is a wireless sensor
network consisting of spatially distributed
autonomous device using sensors to
cooperatively monitor physicalir environmental
conditions, such as temperature, sound,
vibration,pressure,motion or pollutants,at
different locations.
*A collection of sensing devices that that can
be communicate wirelessly.
9. SENSOR NODE:
* Basic unit
sensir network.
* Nodes deployes
either inside or
very close to the
sensed
phenomenon.
