Data aggregation is very important techniques in wireless sensor network. Data aggregations reduce the energy consumption by eliminating redundancy. In this paper, the data aggregation approaches based on the routing protocols and algorithm. Data aggregation is basically used to collect and aggregate data in an energy efficient manner so that network lifetime is improved. Data aggregation protocols aims at eliminating redundant data transmission. The data aggregation is a method used to solve the overlap problems in data centric routing.
