Wireless Sensor Network is a collection of various sensor nodes with sensing and communication capabilities. Clustering is the process of grouping the set of objects so that the objects in the same group are similar to each other and different to objects in the other group. The main goal of Data Aggregation is to collect and aggregate the data by maintaining the energy efficiency so that the network lifetime can be increased. In this paper, I have presented a comprehensive review of various clustering routing protocols for WSN, their advantages and limitation of clustering in WSN. A brief survey of Data Aggregation Algorithm is also outlined in this paper. Finally, I summarize and conclude the paper with some future directions.
