Energy-efficient adaptive slice-based secure data aggregation scheme in WSN

Abstract Wireless Sensor Network (WSN) is increasingly involved in many applications. However, security becomes a huge challenge in current research and it must be taken into consideration in the design of communication mechanism in order to expand the practical scene of sensor network. Secure Data aggregation (SDA) is an effective technology to prevent the network from being compromised and improve the lifetime of WSN. In this paper, we propose an energy-efficient Adaptive Slice-based Secure Data Aggregation (ASSDA) scheme which can promote the network performance under the limitation of node resource. Our method can improve the efficiency of data slicing, reduce the energy consumption of nodes, prolong the network life time and maintain a good privacy preservation level in the same time. Theoretical analysis and simulation show that ASSDA has good performances in terms of privacy-preserving, communication overhead, node energy consumption and network lifetime.
