However, the energy of WSN nodes is limited, so this paper proposes a two-layer WSN system based on edge computing to solve the problems of high energy consumption and short life cycle of WSN data transmission and establishes wireless energy consumption and distance optimization models for sensor networks. Specifically, we propose the optimization objective of balancing load and distance factors. We adopt an improved sparrow search algorithm to evenly distribute sensor nodes in the system to reduce resource consumption, consumption, and network life. Through the simulation experiment, our method is illustrated, effectively reducing the network\u2019s energy consumption by 26.8% and prolonging the network\u2019s life cycle.<\/jats:p>","DOI":"10.3390\/s23177572","type":"journal-article","created":{"date-parts":[[2023,8,31]],"date-time":"2023-08-31T11:45:51Z","timestamp":1693482351000},"page":"7572","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Cluster Head Selection Method for Edge Computing WSN Based on Improved Sparrow Search Algorithm"],"prefix":"10.3390","volume":"23","author":[{"given":"Shaoming","family":"Qiu","sequence":"first","affiliation":[{"name":"Communication and Network Laboratory, Dalian University, Dalian 116622, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1568-0737","authenticated-orcid":false,"given":"Jiancheng","family":"Zhao","sequence":"additional","affiliation":[{"name":"Communication and Network Laboratory, Dalian University, Dalian 116622, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuecui","family":"Zhang","sequence":"additional","affiliation":[{"name":"North Automatic Control Technology Institute, Taiyuan 030006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0916-2087","authenticated-orcid":false,"given":"Ao","family":"Li","sequence":"additional","affiliation":[{"name":"Communication and Network Laboratory, Dalian University, Dalian 116622, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7446-0785","authenticated-orcid":false,"given":"Yahui","family":"Wang","sequence":"additional","affiliation":[{"name":"Communication and Network Laboratory, Dalian University, Dalian 116622, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9591-1514","authenticated-orcid":false,"given":"Fen","family":"Chen","sequence":"additional","affiliation":[{"name":"Communication and Network Laboratory, Dalian University, Dalian 116622, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"161","DOI":"10.1016\/j.matpr.2021.05.067","article-title":"A review paper on wireless sensor network techniques in Internet of Things (IoT)","volume":"51","author":"Gulati","year":"2022","journal-title":"Mater.
