Wireless Sensor Networks (WSNs) have become an active research area for the researchers due to their widely used range of application potential in areas such as target detection and tracking, environmental monitoring, industrial process monitoring, and tactical systems. Usually, after the deployment of sensor nodes in the hazardous, hostile or remote areas, these sensor nodes work on their own. These sensor nodes will have to work with their limited and none replenish able energy resources. Although, energy conservation in communication can be performed in different layers of the TCP/IP protocol suit, energy conservation at MAC layer is found to be the most effective one due to its ability to control the radio directly.
