              Abstract: In-network data aggregation has a great impact   on the energy consumption in large-scale wireless sensor   networks. However, the resource constraints and vulnerable   deployment environments challenge the application of this technique   in terms of security and efficiency. A compromised node may forge   arbitrary aggregation value and mislead the base station into   trusting a false reading. In this paper, we present RAHIM, a   reactive defense to secure data aggregation scheme in cluster-based   wireless sensor networks. The proposed scheme is based on a novel   application of adaptive hierarchical level of monitoring providing   accuracy of data aggregation result in lightweight manner, even if   all aggregator nodes and a part of sensors are compromised in the   network.
