A wireless sensor network consist of large number of nodes that possesses very small battery life and data processing capabilities but these microelectronics system are capable of measuring physical and various environment related consequences like sound, pollution causing agents, etc. Energy efficiency is the major aspect that needs to be taken care of while developing any protocol for the WSNs. This is because of the fact that the SNs are highly constrained in terms of power and their batteries are generally neither’ replaceable nor rechargeable.
