Energy consumption in wireless sensor networks is one of the main challenges for researchers. Many researchers have been done for extending the overall network lifetime by minimizing the power consumption of sensor nodes. Most of the work is done over the MAC layer of network in which different kinds of MAC protocol used by sensor networks. End users typically desire to deploy hundreds to thousands of sensor nodes randomly producing simple, small, and inexpensive devices also limits the energy resources available for sensor node operation.
