An Investigation Of Secure And Energy Efficient Data Aggregation In Wireless Sensor Networks

Abstract The most energy consuming operation in a wireless sensor network is data transmission. The bigger data to be transmitted the more energy is consumed. Therefore minimizing the amount of data to be transferred is very important. Data aggregation appears at this point. Summary of the data of a group of node is transmitted to sink or another node instead of sending all data. Since data aggregation is that much important it is usual to see some counter attacks to overshadow the network process. Also it is natural to see some studies to increase the efficiency of data aggregation process in the literature. In this paper we give an overview about recent secure and energy efficient data aggregation studies. We also referred attack types faced in wireless sensor networks and give some recommendations to cope with them.
