Wireless Sensor Network consists of an enormous number of sensor nodes with data processing and communication facilities. The sensor nodes exceed the gathered data using radio transmitter, to a sink either easily or through other nodes in a multi-hop approach. Wireless sensor network is a power consuming system, since nodes perform on restricted power batteries which decrease its lifetime. The lifetime of the sensor node is based on battery powered devices. Optimally selected modulation and coding is extremely vital technique in wireless sensor networks. This paper provides a detailed study about all the existing energy conservation techniques and also explains about limitations available in the techniques. After having identified the reasons of energy waste in WSNs, we classify energy efficient techniques based on Nodes, MAC Protocols, Networks and Software Levels. We then detail each of Levels.
