OMNET WIRELESS SENSOR NETWORK

Wireless sensor networks is a collection of sensing devices that can communicate wireless.Each device in a wireless sensor networks can sense, process, and talk to its peers.Typically, centralized collection point is located in wireless sensor networks simulation framework using omnet++ simulation.

Components of WSN(Wireless sensor Networks):

Wireless sensor network node has three components. There are,

  • CPU.
  • A radio transceiver.
  • Sensor array.

Features of WSN (hardware):

  • Advanced processing.
  • Interface to the outside world.
  • Short-range.
  • Low power radio.
  • Sensing and basic processing.
