Data aggregation technology is the most practical method to reduce the amount of communication among nodes. Adding a privacy protection mechanism to data aggregation is one of the important means for privacy protection and security in wireless sensor networks. Aiming at certain performance defects of the existing SMART (Slice-Mix-AggRegaTe) privacy protection algorithms, a fat tree-based data aggregation privacy protection algorithm is proposed in this paper, which is referred to as the FTSMART (Fat Tree Slice-Mix-AggRegaTe) algorithm. Concerning the innovative algorithm, the fat tree (FT) is introduced, the fat tree structure is adopted to optimize the data slicing scheme and the aggregation tree generation scheme, and the allocation of fixed time intervals is employed for nodes to reduce the transmission collision in the data aggregation process and to guarantee the completion of the data transmission. The simulation experiment results demonstrate that the FTSMART algorithm has presented the favorable performance in terms of the privacy protection, the network communication overhead, and the data aggregation accuracy.<\/jats:p>","DOI":"10.1155\/2021\/9975912","type":"journal-article","created":{"date-parts":[[2021,9,13]],"date-time":"2021-09-13T21:54:57Z","timestamp":1631570097000},"page":"1-9","source":"Crossref","is-referenced-by-count":3,"title":["A Data Aggregation Privacy Protection Algorithm Based on Fat Tree in Wireless Sensor Networks"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9656-5385","authenticated-orcid":true,"given":"Cheng","family":"Li","sequence":"first","affiliation":[{"name":"College of Computer Science and Technology, Harbin Engineering University, Harbin 150001, China"},{"name":"College of Computer and Control Engineering, Qiqihar University, Qiqihar 161006, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8953-5858","authenticated-orcid":true,"given":"Guoyin","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Harbin Engineering University, Harbin 150001, China"}]},{"given":"Yan","family":"Mao","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Harbin Engineering University, Harbin 150001, China"}]},{"given":"Xin","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Harbin Engineering University, Harbin 150001, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/comst.2006.283821"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/infcom.2007.237"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/tc.1985.6312192"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1145\/844128.844142"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2010.02.026"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/134509"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1002\/dac.2412"},{"issue":"8","key":"8","first-page":"133","article-title":"A low traffic privacy-preserving aggregation algorithm","volume":"23","author":"Q.
