Abstract

The privacy-preserving of information is one of the most important problems to be solved in wireless sensor network (WSN). Privacy-preserving data aggregation is an efective way to protect security of data in WSNs. In order to deal with the problem of energy consumption of the SMART algorithm, we present a new dynamic slicing D-SMART algorithm which based on the importance degree of data. The proposed algorithm can decrease the communication overhead and energy consumption efectively while provide good performance in preserving privacy by the reasonable slicing based on the importance degree of the collected raw data. Simulation results show that the proposed D-SMART algorithm improve the aggregation accuracy, enhance the privacy-preserving, reduce the communication overhead to some extent, decrease the energy consumption of sensor node and prolong the network lifetime indirectly.

6 Conclusion

Based on the analysis and study of other wireless sensor network security protection algorithms in terms of communication overhead, aggregation accuracy and the performance of privacy protection. We propose the D-SMART algorithm which improves the disadvantage of data aggregation accuracy and privacy protection of the SMART algorithm. Meanwhile reducing the data trafc, saving the energy consumption and prolonging the network lifetime. Data integrity is also a challenge for data security protection. In the future, we will extend the data integrity on the basis of the D-SMART algorithm, we will protect the data integrity while protecting data privacy
