Sensor Networks are systems with restrict resources that are scattered on a large scale with numerous deployment density and are used in aggregating data in a intelligent style. In this paper the concept of "efficient energy consumption" in routing protocol of sensor network, which causes to increase the lifetime of sensor network, has been studied and a taxonomy of various techniques for efficient energy consumption is presented. Also a new routing protocol is presented in a way that proposal protocol uses some special techniques to consume energy efficiently. After that the authors have simulated proposal routing protocol and compared its function with recent protocols and the authors have observed that proposal routing protocol increase the lifetime of sensor networks.
