Abstract
Wireless sensor networks(WSNs) is an important part of Internet of Things(IoT).Privacy-preserving in data aggregating is an effective way to protect security of data in WSN.SMART is one of data aggregation algorithms.This paper presents some optimizing factors used to enhance performance of SMART scheme in terms of privacy-preserving and data aggregating precision.Based on the optimal parameters,it proposes some new data aggregating schemes,which reduce communication overhead and then the energy consumption.Therefore,they prolong the lifetime of the network.Simulation results show that the proposed schemes P-SMART-CLPNT demonstrate good performance in data aggregation precision,communication overhead,and privacy-preserving with the optimal parameters.
