A Survey on Secure Data Aggregation Techniques in Wireless Sensor Networks

N.Vidhya, Dr.P.Sengottuvelan

Wireless Sensor Networks (WSN) consists huge number of sensor nodes usually set up in isolated and hostile area that are limited sensing, computation and communication capabilities. Due to resource limited sensor nodes, need to focus to decrease the amount of data communication. Data aggregation is the process in which information is gathered and expressed in a summary form in order to decrease the amount of data communication in the network. To improve energy efficiency of sensor network, Data aggregation protocols aim to merge and sum up data packets of several sensor nods and also classify and filter data from the compromised nodes. This paper retrieves about techniques available in data aggregation with security.
