摘　　要：在无线传感器网络(WSNs)中如何有效聚合数据是当前物联网应用中的重要挑战。然而在已有的若干解决方案中,传感器的计算和通信过程消耗了较高的能量,数据的隐私性和完整性得不到有效保障。针对上述问题,提出一种基于分簇的数据聚合机制,采用代数方程计算传感器的中间数据聚合值,采用数字签名进行簇间传感器的身份认证。实验表明:该机制能有效降低传感器计算和通信的耗能,保证数据的隐私性和完整性。In wireless sensor networks （WSNs）, how to, aggregate data efficiently is the major challenge for applications of the Internet of things. However, in existing schemes for fhis challenge, sensor nodes usually suffer from high energy consumption of communication and calculation, and privacy and integrity of datas cannot be protected effectively. Aimed at these problems, a data aggregation scheme based on clustering is proposed, algebraic equation is used to compute intermediate data aggregation value of sensor and digital signature is used for ID authentication of sensors between clusters. Experimental results show that the proposed scheme effectively reduce energy consumption of calculation and communication, and ensure privacy and integrity of datas.
