A Wireless Sensor Networks (WSN) is a type of self organizing and self managing network which is not made of permanently of sensor nodes of the condition of not having internet infrastructure. A wireless sensor network consists of a large number of nodes spread over a specific area where the authors want to look after at the changes going on there.
