摘要: 为在无线传感器网络(WSN)的数据收集、处理和传输过程中降低能耗,提高数据的安全性与机密性,提出一种动态分簇安全数据汇聚算法CDSDA。对基于分簇的WSN安全数据汇聚算法CSDA进行改进,依据节点所采集数据的重要程度与节点的剩余能量,对数据进行动态切片,在此基础上,进行簇内汇聚和簇间汇聚以得到最终结果。仿真结果表明,与CSDA算法相比,CDSDA算法在通信开销、数据正确率、数据隐私保护等方面具有较好性能。

Abstract: In order to reduce energy consumption and improve data security and confidentiality in the process of data collection,processing and transmission in Wireless Sensor Networks(WSN),a dynamic clustering secure data aggregation algorithm CDSDA is proposed.The clustering-based WSN secure data aggregation algorithm CSDA is improved.According to the importance of data collected by nodes and the residual energy of nodes,the data is sliced dynamically.On this basis,intra-cluster aggregation and inter-cluster aggregation are carried out to get the final results.Simulation results show that,compared with CSDA algorithm,CDSDA algorithm has better performance in communication overhead,data accuracy,data privacy protection and so on.

Key words: Wireless Sensor Networks(WSN), clustering structure, data aggregation, dynamic slicing, privacy protection
