Wireless sensor network consisting of various tiny wireless sensor nodes that are equipped with transmission devices that require some amount of energy to transmit the data to other node(s). Most often the battery of sensor nodes cannot be charged or changed during transmission. To preserve the longetivity of the network it is very challenging task to build a sensor node that require very little amount of energy for data transmission. Lifetime of wireless sensor network is directly proportional to the energy source of wireless sensor node.
