In order to keep the present and\n past positions of the objects in secondary memory, each update introduces an\n I\/O and this process is sometimes creating a bottleneck. In this paper we\n deal with the problem of minimizing the number of I\/Os in such a way that\n queries concerning the present and past positions of the objects can be\n answered efficiently. In particular we propose two new approaches that\n achieve an asymptotically optimal number of I\/Os for performing the necessary\n updates. The approaches are based on the assumption that the primary memory\n suffices for storing the current positions of the objects.<\/jats:p>","DOI":"10.2298\/csis111127040l","type":"journal-article","created":{"date-parts":[[2012,10,16]],"date-time":"2012-10-16T14:11:02Z","timestamp":1350396662000},"page":"173-195","source":"Crossref","is-referenced-by-count":1,"title":["Indexing moving objects: A real time approach"],"prefix":"10.2298","volume":"10","author":[{"given":"George","family":"Lagogiannis","sequence":"first","affiliation":[{"name":"Agricultural University of Athens, Iera Odos, Athens, Greece"}]},{"given":"Nikos","family":"Lorentzos","sequence":"additional","affiliation":[{"name":"Agricultural University of Athens, Iera Odos, Athens, Greece"}]},{"suffix":"B.","given":"Alexander","family":"Sideridis","sequence":"additional","affiliation":[{"name":"Agricultural University of Athens, Iera Odos, Athens, Greece"}]}],"member":"1078","container-title":["Computer Science and Information Systems"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T08:30:44Z","timestamp":1685349044000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1820-02141200040L"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2013]]}},"URL":"https:\/\/doi.org\/10.2298\/csis111127040l","relation":{},"ISSN":["1820-0214","2406-1018"],"issn-type":[{"value":"1820-0214","type":"print"},{"value":"2406-1018","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013]]}}}
