We propose to use the ground terminal-UAV (G-U) region for the energy consumption model. In particular, to fulfill the data collection task with a minimum energy both of the GTs and UAV, an algorithm that combines optimal trajectory design and resource allocation scheme is proposed which is supposed to solve the optimization problem approximately. We initialize the UAV\u2019s trajectory firstly. Then, the optimal UAV trajectory and GT\u2019s resource allocation are obtained by using the successive convex optimization and Lagrange duality. Moreover, we come up with an efficient algorithm aimed to find an approximate solution by jointly optimizing trajectory and resource allocation. Numerical results show that the proposed solution is efficient. Compared with the benchmark scheme which did not adopt optimizing trajectory, the solution we propose engenders significant performance in energy efficiency.<\/jats:p>","DOI":"10.1155\/2019\/9647539","type":"journal-article","created":{"date-parts":[[2019,8,25]],"date-time":"2019-08-25T19:31:27Z","timestamp":1566761487000},"page":"1-14","source":"Crossref","is-referenced-by-count":13,"title":["UAV-Enabled Data Collection: Multiple Access, Trajectory Optimization, and Energy Trade-Off"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5608-3106","authenticated-orcid":true,"given":"Lin","family":"Xiao","sequence":"first","affiliation":[{"name":"Information Engineering School, Nanchang University, Nanchang 330031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5938-3611","authenticated-orcid":true,"given":"Yipeng","family":"Liang","sequence":"additional","affiliation":[{"name":"Information Engineering School, Nanchang University, Nanchang 330031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chenfan","family":"Weng","sequence":"additional","affiliation":[{"name":"Information Engineering School, Nanchang University, Nanchang 330031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5313-4481","authenticated-orcid":true,"given":"Dingcheng","family":"Yang","sequence":"additional","affiliation":[{"name":"Information Engineering School, Nanchang University, Nanchang 330031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0812-3470","authenticated-orcid":true,"given":"Qingmin","family":"Zhao","sequence":"additional","affiliation":[{"name":"Information Engineering School, Nanchang University, Nanchang 330031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2019.2893615"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/MNET.2019.1800431"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/access.2018.2872736"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/lwc.2014.2342736"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2016.2531652"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/lcomm.2016.2578312"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/mcom.2011.5783982"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/access.2019.2922651"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.3390\/s19071491"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2017.2688328"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2017.2789293"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2017.2751045"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1109\/tcomm.2018.2865922"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/mwc.2017.1600343"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1109\/lwc.2016.2604306"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2018.2816244"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1109\/lcomm.2017.2772254"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1109\/lcomm.2016.2633248"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2018.2790401"},{"year":"2004","key":"27"}],"container-title":["Wireless Communications and Mobile Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/9647539.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/9647539.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/9647539.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,19]],"date-time":"2019-09-19T18:43:04Z","timestamp":1568918584000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/wcmc\/2019\/9647539\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,8,25]]},"references-count":20,"alternative-id":["9647539","9647539"],"URL":"https:\/\/doi.org\/10.1155\/2019\/9647539","relation":{},"ISSN":["1530-8669","1530-8677"],"issn-type":[{"type":"print","value":"1530-8669"},{"type":"electronic","value":"1530-8677"}],"subject":[],"published":{"date-parts":[[2019,8,25]]}}}
