      • A sensor network is a system of one or more sensors that detect, collect and possibly respond to things or events.
      • Large number of sensor nodes, which are densely deployed either inside the phenomenon or very close to it.
      • Inter-connected sensor nodes exchanging sensed data by wired or wireless processing.
