With increasing nodes in the wireless sensor network, widely existing clock skew, increased geometrically, is bringing about greater energy consumption. Due to the random distribution of nodes, in order to improve the transmission efficiency and reduce the computational load of the coordinator, the node processor needs to the use edge computing for preliminary analysis. This paper puts forward an improved energy-efficient reference broadcast synchronization algorithm (ERBS). This algorithm firstly calculates the average phase offset of nonadjacent nodes in the network after receiving a message. It then uses the least square method to solve the clock skew to achieve high-precision synchronization of the whole network. Simulation results show that compared with RBS, the time synchronization precision of ERBS is greatly improved and synchronization times are greatly reduced, decreasing energy consumption significantly.<\/jats:p>","DOI":"10.1155\/2020\/8840367","type":"journal-article","created":{"date-parts":[[2020,11,21]],"date-time":"2020-11-21T23:05:06Z","timestamp":1605999906000},"page":"1-11","source":"Crossref","is-referenced-by-count":8,"title":["Edge Computing-Based ERBS Time Synchronization Algorithm in WSNs"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9960-1003","authenticated-orcid":true,"given":"Xianbo","family":"Sun","sequence":"first","affiliation":[{"name":"School of Information Engineering, Hubei Minzu University, Enshi 445000, China"},{"name":"School of Automation, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3143-3939","authenticated-orcid":true,"given":"Yixin","family":"Su","sequence":"additional","affiliation":[{"name":"School of Automation, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Hubei Minzu University, Enshi 445000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianjun","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Hubei Minzu University, Enshi 445000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinqiao","family":"Yi","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Hubei Minzu University, Enshi 445000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Hubei Minzu University, Enshi 445000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Hubei Minzu University, Enshi 445000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/S1389-1286(01)00302-4"},{"issue":"7","key":"2","first-page":"1282","article-title":"Wireless sensor networks","volume":"14","author":"F.
