With the evolution of wireless technologies Wireless Sensor Network(WSN) have gained tremendous exposure in field of sensing remote places. For researchers WSN has been most sought for field due to its wide area of applications and usefulness. Day by day new technologies are evolving with new and efficient features, which keep this field live for development and research oriented work. The key component of WSN, the sensor nodes, is equipped with the required hardware resources and limited energy to spend for the task assigned. So there are requirements to improvise the energy consumption is WSN nodes to increase its life time. There has been various effort put forth for increasing the lifetime of the sensor nodes by adapting to various changes in the techniques at each layer of the sensor node design. The proposed review paper identifies the ways the energy conservation works and been worked upon by researchers apart from clustering and routing.
