In this paper, the authors presents a review on the data aggregation techniques and energy efficient WSNs. Data aggregation techniques has become an significant part of WSNs to overcome the problem of flooding at the base station, a lot. Also data aggregation techniques reduce the communication cost of WSNs; because it reduces the redundant data by aggregation. The overall goal of this paper is to review various data aggregation techniques used in WSNs. This paper has also reviewed various homogeneous and heterogeneous WSNs routing protocols. This paper ends up with the short comings of data aggregation techniques and also clustering based protocols.
