Wireless Sensor Network technology has been a standout amongst the most transforming and gives power to technologies recent year. Sensor node collects all sensed data and sends to the sink node in wireless sensor network. The situation of the sink hub has a huge effect the energy utilization and lifetime of WSNs. All collected data transmitted in wireless sensor network from one node to another node communicate to the sink node. Data aggregation is an outstanding methodology in WSN and it is a process of gathering and aggregating the information from various sensors to give joined data to the base station. These processes repeat much time collecting these data efficiently that reduce the energy consumption of data transmission in wireless sensor networks. In wireless sensor network, different data aggregation approach is used for data aggregation. In this paper, we study much paper regarding enhance the lifetime of the sensor and reduce the energy consumption in a wireless sensor network. Overall apply many data aggregation algorithm are used in WSNs it helps to reduce the energy consumption and increase the lifetime of WSNs.
