A modified scheme for privacy-preserving data aggregation in WSNs

Wireless Sensor Networks (WSNs) have been wildly used in our daily life. How to collect data efficiently and keep users´ privacy are more and more important. The goal of this paper is to find a new effective scheme to solve this problem. In this paper, I propose a modified scheme for privacy preserving data aggregation which is inspired by CPDA. This scheme could aggregate data without revealing any private information and consume less resources than CPDA. In addition, I made a comparison with CPDA in computation overhead and communication overhead. At last, the simulation results are presented which show the efficacy and efficiency of this scheme.
