To address the lack of intelligent and the low efficiency of conventional leakage detection methods, this paper designs a leakage detection method based on machine learning and wireless sensor networks (WSNs). The system employs wireless sensors installed on pipelines to collect data and utilizes the 4G network to perform remote data transmission. A leakage triggered networking method is proposed to reduce the wireless sensor network\u2019s energy consumption and prolong the system life cycle effectively. To enhance the precision and intelligence of leakage detection, we propose a leakage identification method that employs the intrinsic mode function, approximate entropy, and principal component analysis to construct a signal feature set and that uses a support vector machine (SVM) as a classifier to perform leakage detection. Simulation analysis and experimental results indicate that the proposed leakage identification method can effectively identify the water pipeline leakage and has lower energy consumption than the networking methods used in conventional wireless sensor networks.<\/jats:p>","DOI":"10.3390\/s19235086","type":"journal-article","created":{"date-parts":[[2019,11,22]],"date-time":"2019-11-22T02:49:27Z","timestamp":1574390967000},"page":"5086","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":112,"title":["Water Pipeline Leakage Detection Based on Machine Learning and Wireless Sensor Networks"],"prefix":"10.3390","volume":"19","author":[{"given":"Yang","family":"Liu","sequence":"first","affiliation":[{"name":"College of Electronic Information Engineering, Inner Mongolia University, Hohhot 010021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuehui","family":"Ma","sequence":"additional","affiliation":[{"name":"College of Electronic Information Engineering, Inner Mongolia University, Hohhot 010021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuting","family":"Li","sequence":"additional","affiliation":[{"name":"College of Electronic Information Engineering, Inner Mongolia University, Hohhot 010021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5743-9610","authenticated-orcid":false,"given":"Yong","family":"Tie","sequence":"additional","affiliation":[{"name":"College of Electronic Information Engineering, Inner Mongolia University, Hohhot 010021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinghui","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Electronic Information Engineering, Inner Mongolia University, Hohhot 010021, China"},{"name":"Department of Electrical and Computer Engineering, University of Nebraska-Lincoln, Lincoln, NE 68588, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Gao","sequence":"additional","affiliation":[{"name":"Tianjin Key Laboratory of Wireless Mobile Communications and Power Transmission, Tianjin Normal University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,21]]},"reference":[{"key":"ref_1","first-page":"314","article-title":"Water security-national and global issues","volume":"30","author":"Tindall","year":"2010","journal-title":"Sex.
