Energy efficient and secure data aggregation with malicious aggregator node detection (ESMD) in WSNs

Energy efficient and secure data aggregation with malicious aggregator node detection in wireless sensor network is an important field of research. In wireless sensor network, data collected by leaf sensor nodes are aggregated at intermediate nodes and sink node. To minimize energy consumption, in-network aggregation of sense data at intermediate sensor nodes routed to the sink node. Aggregation reduces the transmission delay and improves lifetime of sensor networks. We propose energy efficient and secure data aggregation model that can detect malicious aggregator node. In our proposed solution, data aggregation result signed with secret key of aggregator node so that it can't be changed by others.
