In recent years, the use of wireless sensor networks for industrial applications has been rapidly growing and wireless sensor devices are generally battery operated devices which have limited battery power. Since sensor nodes are small in size, cost-efficient, low-power devices, and have limited battery power supply. Wireless Sensor Networks (WSNs) are mostly deployed in a remote working environment, once deployment is done; it is not possible to replace the battery and energy. A fundamental challenge in the design of Wireless Sensor Network is to enhance the network lifetime. In this paper different techniques are discuss.

Keywords: wireless sensor network, network lifetime, energy conservation, sensor node.
