This paper present a review on the data aggregation techniques in WSNs. Data aggregation techniques have become an major part of WSNs to overcome the problem of flooding at the base station. Also data aggregation techniques reduce the communication cost of WSNs; because it reduces the redundant data by aggregation. Various data aggregation techniques have been considered in this paper. The data aggregation results in reduction of redundant data therefore reduce the amount of data transmission packets size which will reduce the energy consumption in each round. This paper ends with the shortcoming of data aggregation techniques.
