While data items are being broadcast, update transactions may install new values for the data items. If the executions of update and broadcast of data items are interleaved without any control, the mobile transactions may observe inconsistent data values. In this paper, we propose a serialization checking method (SCM) for concurrency control between read-only mobile transactions and update transactions. SCM is based on the framework of an earlier algorithm, Update First with Ordering (UFO), but improves on that algorithm by reducing re-broadcast overhead when the probability of data conflict between updates and data broadcast is high. Simulation experiments have been performed to investigate the performance characteristics of the proposed method. <\/jats:p>","DOI":"10.1142\/s0219265901000361","type":"journal-article","created":{"date-parts":[[2003,5,7]],"date-time":"2003-05-07T04:18:55Z","timestamp":1052281135000},"page":"253-267","source":"Crossref","is-referenced-by-count":1,"title":["CONCURRENCY CONTROL FOR MOBILE SYSTEMS WITH DATA BROADCAST"],"prefix":"10.1142","volume":"02","author":[{"given":"MEI-WAI","family":"AU","sequence":"first","affiliation":[{"name":"Department of Computer Science, City University of Hong Kong, 83 Tat Chee Avenue, Kowloon, China"}]},{"given":"EDWARD","family":"CHAN","sequence":"additional","affiliation":[{"name":"Department of Computer Science, City University of Hong Kong, 83 Tat Chee Avenue, Kowloon, China"}]},{"given":"KAM-YIU","family":"LAM","sequence":"additional","affiliation":[{"name":"Department of Computer Science, City University of Hong Kong, 83 Tat Chee Avenue, Kowloon, China"}]}],"member":"219","published-online":{"date-parts":[[2012,1,25]]},"reference":[{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.1007\/BF02117288"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1093\/comjnl\/40.7.401"}],"container-title":["Journal of Interconnection Networks"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0219265901000361","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,7]],"date-time":"2019-08-07T10:40:43Z","timestamp":1565174443000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0219265901000361"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,9]]},"references-count":2,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2012,1,25]]},"published-print":{"date-parts":[[2001,9]]}},"alternative-id":["10.1142\/S0219265901000361"],"URL":"https:\/\/doi.org\/10.1142\/s0219265901000361","relation":{},"ISSN":["0219-2659","1793-6713"],"issn-type":[{"value":"0219-2659","type":"print"},{"value":"1793-6713","type":"electronic"}],"subject":[],"published":{"date-parts":[[2001,9]]}}}
