Wireless Sensor Network is broadly used in many areas including security surveillance. As sensor nodes use energy from batteries for sensing the data and transmitting data, it consumes the energy for these operations. Optimizing energy consumption in sensor nodes is an emerging research area in today’s era and also a challenging task, Energy consumption of nodes is a great challenge in order to maximize network lifetime. Unlike other networks, it can be hazardous, very expensive or even impossible to charge or replace exhausted batteries due to the hostile and inaccessible nature of environment.
