Survey: Robust Data Aggregation Techniques in Wireless Sensor Networks

Data aggregation in important issue in WSN’s. Because with the help of data aggregation; we are reduce energy consumption in the network. In the Ad-hoc sensor network have the most challenging task is to maintain a life time of the node. due to efficient data aggregation increase the life of the network. In this paper, we are going to provide the information about the type of the network and which data aggregation algorithm is best. In big scale sensor network, energy economical, data collection and query distribution in most important.
