The first one is an optimization scheme that avoids void hole occurrence and minimizes the uncertainty in the position estimation of glider\u2019s. The second one is a cooperative routing scheme that reduces the packet drop ratio by using the relay cooperation. Both techniques use gliders that stay at sojourn positions for a predefined time, at sojourn position self-confidence (s-confidence) and neighbor-confidence (n-confidence) regions that are estimated for balanced energy consumption. The transmission power of a glider is adjusted according to those confidence regions. Simulation results show that our proposed schemes outperform the compared existing one in terms of packet delivery ratio, void zones and energy consumption.<\/jats:p>","DOI":"10.3390\/s17030580","type":"journal-article","created":{"date-parts":[[2017,3,13]],"date-time":"2017-03-13T10:26:18Z","timestamp":1489400778000},"page":"580","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Cooperative Position Aware Mobility Pattern of AUVs for Avoiding Void Zones in Underwater WSNs"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3777-8249","authenticated-orcid":false,"given":"Nadeem","family":"Javaid","sequence":"first","affiliation":[{"name":"COMSATS Institute of Information Technology, Islamabad 44000, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mudassir","family":"Ejaz","sequence":"additional","affiliation":[{"name":"COMSATS Institute of Information Technology, Islamabad 44000, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6871-6633","authenticated-orcid":false,"given":"Wadood","family":"Abdul","sequence":"additional","affiliation":[{"name":"Research Chair of Pervasive and Mobile Computing, College of Computer and Information Sciences, King Saud University, Riyadh 11633, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1887-5193","authenticated-orcid":false,"given":"Atif","family":"Alamri","sequence":"additional","affiliation":[{"name":"Research Chair of Pervasive and Mobile Computing, College of Computer and Information Sciences, King Saud University, Riyadh 11633, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8253-9709","authenticated-orcid":false,"given":"Ahmad","family":"Almogren","sequence":"additional","affiliation":[{"name":"Research Chair of Pervasive and Mobile Computing, College of Computer and Information Sciences, King Saud University, Riyadh 11633, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iftikhar","family":"Niaz","sequence":"additional","affiliation":[{"name":"COMSATS Institute of Information Technology, Islamabad 44000, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadra","family":"Guizani","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Purdue University, West Lafayette, IN 47907, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,3,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2490","DOI":"10.1109\/TWC.2014.031914.131203","article-title":"A QoS-aware underwater optimization framework for inter-vehicle communication using acoustic directional transducers","volume":"13","author":"Chen","year":"2014","journal-title":"IEEE Trans.
