Wireless Sensor Networks (WSNs) is the collection of large number of low powered sensor nodes deployed for sensing & monitoring real world physical phenomenon like temperature, humidity, soil moisture, pressure, etc. Due to low powered battery and unattended deployment of sensor nodes, conserving sensor node energy requirement is one of the prime challenges in WSN. Satisfactory coverage of sensing area requires sensor nodes to be deployed densely which causes the real time observation to be associated spatially or temporally. Due to such dense deployment, there may be a situation where in more than one sensor node captures and communicates the same physical phenomenon which hints that data aware energy conservation technique may be applied in order to reduce the overall power requirement of the network.
