In WSNs, Energy is a scarcest resource of sensor nodes and it determines the lifetime of sensor nodes.These are battery powered sensor nodes.These small batteries have limited power and also may not easily rechargeable or removable.Long communication distance between sensors and a sink can greatly drain the energy of sensors and reduce the lifetime of a network.In WSNs, energy is a big factor to be considered.Various techniques are used to optimize energy level of sensor nodes of WSN.We will make a review of some of these wireless sensor network techniques which are used recently and are helpful in improving energy efficiency of wireless sensor nodes.
