The lifetime of a sensor network is closely linked to the nodal life. The latter depends mainly on the power consumption of the node. We presented in this work some approaches to energy conservation in wireless sensor networks. The first area of energy conservation techniques aimed at reducing the duty-cycle nodes. This results in the reduction in the duration of radio activity to avoid excessive energy consumption due to communication. In this context, several methods have emerged either as MAC protocols low Duty-cycle or as independent higher-level protocols based on authorizations Sleep / Wakeup. The objective of this work is to do a thorough study on energy consumption in wireless sensor networks. The study points addressed are at the level of media access protocol or MAC protocol
