One of the most important issues in wireless sensor networks is reducing energy consumption [40, 37and 47]. This matter has forced many researchers to look for methods to solve this issue. In recent years, so many methods have been proposed. And in this research, the most recent ones have been studied. Different issues such as lifetime of the network, primary energy, node density, type of transfer (multi hops or single hop) have been considered here for they are the key factors in energy consumption as well as the lifetime of a wireless sensor network. It has also been tried to examine issues such as FND, LND as the main ones. Having considered the weak and strong points of the previous studies, new ways have been presented to control the energy consumption while to increase the efficacy of network lifetime. This study has been aimed to recognize the advantages and disadvantages of previous methods and to present suggestions for future efforts Surveying similar methods of 2011 and 2012 [21, 32, 38, 40 and 47] has been looked at as one of the aims of this study,
