An Improved Secure Data Aggregation Algorithm in Wireless Sensor Networks

The related key technologies of Wireless Sensor Networks(WSNs) secure data aggregation was compared.Then an effective data aggregation algorithm(EDAA) was proposed after the distributed algorithm in data aggregation was analyzed.The algorithm was simulated in NS2 software,and the result shows that the data aggregation algorithm EDAA can effectively reduce the transmission costs and the energy consumption of nodes.
