With the aid of recent developments in ubiquitous data computing, an increasing number of users are expected to overcome low accessibility by applying queries to underwater sensor networks. However, when multiple users send queries to an underwater sensor network in a disorganized manner, it may incur lethal energy waste and problematic network traffic. The current query management mechanisms cannot effectively deal with this matter due to their limited applicability and unrealistic assumptions. In this paper, a novel query management scheme involving query result merging is proposed for underwater sensor networks. The mechanism is based on a relational database model and is adjusted to the practical restrictions affecting underwater communication environments. Network simulations will prove that the scheme becomes more efficient with a greater number of queries and a smaller period range.<\/jats:p>","DOI":"10.3390\/s111211833","type":"journal-article","created":{"date-parts":[[2011,12,20]],"date-time":"2011-12-20T16:40:37Z","timestamp":1324399237000},"page":"11833-11855","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A Query Result Merging Scheme for Providing Energy Efficiency in Underwater Sensor Networks"],"prefix":"10.3390","volume":"11","author":[{"given":"Yunsung","family":"Kim","sequence":"first","affiliation":[{"name":"Korean Minjok Leadership Academy, 1300, Sosa-ri, Anheung-myeon, Hoengseong-gun, Gangwon-do, 225-823, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soo-Hyun","family":"Park","sequence":"additional","affiliation":[{"name":"The Graduate School of Business IT, Kookmin University, 861-1, Jeongneung-dong Sungbuk-gu, Seoul, 136-702, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2011,12,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1016\/S1389-1286(01)00302-4","article-title":"Wireless Sensor Networks: A Survey","volume":"38","author":"Akyildiz","year":"2002","journal-title":"Comput.
