In the proposed scheme, we introduce a mobile sink (MS), i.e., an autonomous underwater vehicle (AUV), and also courier nodes (CNs), to minimize the energy consumption of nodes. MS and CNs stop at specific stops for data gathering; later on, CNs forward the received data to the MS for further transmission. By the mobility of CNs and MS, the overall energy consumption of nodes is minimized. We perform simulations to investigate the performance of the proposed scheme and compare it to preexisting techniques. Simulation results are compared in terms of network lifetime, throughput, path loss, transmission loss and packet drop ratio. The results show that the proposed technique performs better in terms of network lifetime, throughput, path loss and scalability.<\/jats:p>","DOI":"10.3390\/s16030404","type":"journal-article","created":{"date-parts":[[2016,3,21]],"date-time":"2016-03-21T11:14:24Z","timestamp":1458558864000},"page":"404","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":60,"title":["Efficient Data Gathering in 3D Linear Underwater Wireless Sensor Networks Using Sink Mobility"],"prefix":"10.3390","volume":"16","author":[{"given":"Mariam","family":"Akbar","sequence":"first","affiliation":[{"name":"COMSATS Institute of Information Technology, Islamabad 44000, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3777-8249","authenticated-orcid":false,"given":"Nadeem","family":"Javaid","sequence":"additional","affiliation":[{"name":"COMSATS Institute of Information Technology, Islamabad 44000, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayesha","family":"Khan","sequence":"additional","affiliation":[{"name":"COMSATS Institute of Information Technology, Islamabad 44000, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad","family":"Imran","sequence":"additional","affiliation":[{"name":"College of Computer and Information Sciences, King Saud University, Riyadh 11451, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad","family":"Shoaib","sequence":"additional","affiliation":[{"name":"College of Computer and Information Sciences, King Saud University, Riyadh 11451, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Athanasios","family":"Vasilakos","sequence":"additional","affiliation":[{"name":"Lulea University of Technology, Lulea 97187, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"795","DOI":"10.3390\/s140100795","article-title":"Underwater acoustic wireless sensor networks: Advances and future trends in physical, MAC and routing layers","volume":"14","author":"Climent","year":"2014","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Karim, L., Mahmoud, Q.H., Qusay, H., Nasser, N., and Khan, A.A.N.
