摘　　要：针对传统无线传感器网络数据聚合算法存在隐私保护性较低和需要大量通信量的问题,研究并提出了一种基于无线传感器网络数据聚合技术的隐私保护方案。所提出的算法一方面使用部分数据交换策略以减少数据串通阶段不必要的数据交换,另一方面使用随机发送策略以提高数据聚合和的精度。同时,文中采用TOSSIM方法测试了所提算法的数据通信量、隐私性和数据聚合精度。测试结果表明,改进算法具有更高的通信效率、更精确的数据聚合结果。并能满足隐私保护的要求,具有一定的实用性和有效性。Aiming at the problems of traditional data aggregation algorithms in wireless sensor networks,such as low privacy protection and large amount of traffic,a privacy protection scheme based on wireless sensor network data aggregation technology is proposed and proposed. The proposed algorithm,on the one hand,uses partial data exchange strategy to reduce unnecessary data exchange during data collation,and on the other hand uses random sending strategy to improve the accuracy of data aggregation. At the same time,this paper uses TOSSIM method to test the data traffic,privacy and data aggregation accuracy of the proposed algorithm. The test results show that the improved algorithm has higher communication efficiency and more accurate data aggregation results,and can meet the privacy protection requirements,Has a certain practicality and effectiveness.
