SECURE AND EFFICIENT DATA AGGREGATION ARCHITECTURE
Abstract

Author(s): Aparna Chandran

A wireless sensor network consists of spatially distributed autonomous and efficient sensors to monitor environmental conditions and physical conditions. In wireless sensor network, one of the widely used techniques is data aggregation. There has been many related papers and works proposed to address this data aggregation technique. However less of them pay attention to the property of data integrity. An attacker can simply modify data to affect the decision of base station by compromised nodes. Therefore, a new efficient and secure data aggregation architecture is proposed to find the compromised nodes and help the base station to verify the final results.
