Many wireless sensor network (WSN) applications require privacy-preserving aggregation of sensor data during transmission from the source nodes to the sink node. In this paper, we explore several existing privacy-preserving data aggregation (PPDA) protocols for WSNs in order to provide some insights on their current status. For this, we evaluate the PPDA protocols on the basis of such metrics as communication and computation costs in order to demonstrate their potential for supporting privacy-preserving data aggregation in WSNs. In addition, based on the existing research, we enumerate some important future research directions in the field of privacy-preserving data aggregation for WSNs.
许多无线传感器网络（WSN）应用程序需要在源节点到汇聚节点的传输过程中对传感器数据进行隐私保护聚合。在本文中，我们探讨了几种现有的无线传感器网络隐私保护数据聚合（PPDA）协议，以便了解它们的现状。为此，我们根据通信和计算成本等指标对 PPDA 协议进行评估，以展示它们在支持 WSN 中隐私保护数据聚合方面的潜力。此外，根据现有研究，我们列举了无线传感器网络隐私保护数据聚合领域的一些重要的未来研究方向。
