An Enforcing Integrity and Privacy-Preserving Data Aggregation Protocol in Wireless Sensor Network

Abstract

It is important to ensure the integrity of the aggregation result and quality of communication among node in wireless sensor network in the condition of high-efficient privacy-preserving data aggregation mechanism. In this paper, we propose a method based on reputation model to solve this problem. During the process of data aggregation, the cluster head node will choose the node with max reputation value as collaborative node to accomplish the aggregation process. To show the efficacy and efficiency of this method, we present the simulation results. The simulation results show that our method iE-CPDA(enforced Integrity Energy-efficient Cluster-based Privacy-preserving Data Aggregation) has less communication and computation and higher accuracy than iCPDA.
