A Novel Approach for Secure Data Aggregation in Wireless Sensor Networks

The Wireless Sensor Networks (WSNs) are composed of resource starved sensor nodes that are deployed to sense, process and communicate vital information to the base station. Due to the stringent constraints on the resources in the sensor nodes on one hand and due to the communications costs being always significantly higher than the data processing costs, the WSNs typically, employ in-network processing, which aims at reducing effectively, the total number of packets eventually transmitted to the base station. Such in-network processing largely employs data aggregation operations that aggregate the data into a compact representation for further transmission.
