Wireless sensor network is a growing field. Energy resource is very restricted in wireless sensor network. Sensor network are used for several application. Sensor network still faces downside in delivering data from source to sink. Routing algorithm are developed for this data transmission from source to sink. Energy saving is the most significant issue related to wireless sensor networks. There are several algorithms introduced to date for reducing the energy consumption in wireless sensor network. In this paper numerous algorithm are mentioned to improve the lifespan of the network. Opportunistic routing algorithm plays an important role for energy saving. Moto of this paper is to provide an overview of reported energy efficient algorithms employed in wireless sensing element network.
