In addition to proposing a new frame structure, the article also considers the Signal-to-Noise (SNR) constraint to guarantee that the HAP can successfully receive data from wireless stations. In the article, the problem of minimization of energy consumption is formulated as a nonlinear programming model. We employ the SQP (Sequential Quadratic Programming) algorithm to figure out the optimal solution. Moreover, a heuristic method is proposed as well to obtain a near-optimal solution in a shorter time. The simulation results showed that the proposed scheme outperforms the related work in terms of energy consumption and energy efficiency.<\/jats:p>","DOI":"10.3390\/s24175535","type":"journal-article","created":{"date-parts":[[2024,8,27]],"date-time":"2024-08-27T06:19:01Z","timestamp":1724739541000},"page":"5535","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Energy Consumption Minimization with SNR Constraint for Wireless Powered Communication Networks"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5060-9266","authenticated-orcid":false,"given":"Kuei-Ping","family":"Shih","sequence":"first","affiliation":[{"name":"Department of Computer Science and Information Engineering, Tamkang University, New Taipei City 251301, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Sheng","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, Tamkang University, New Taipei City 251301, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yen-Da","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Computer Information and Network Engineering, Lunghwa University of Science and Technology, Taoyuan 333326, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"San-Yuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, I-Shou University, Kaohsiung 811022, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1329","DOI":"10.1109\/COMST.2018.2797886","article-title":"Beamforming in Wireless Energy Harvesting Communications Systems: A Survey","volume":"20","author":"Alsaba","year":"2018","journal-title":"IEEE Commun.
