Different compression techniques are applied for this purpose, offering general solutions which try to minimize the loss of information. Here, a new proposal for traffic reduction by redefining the domains of the sensor data is presented. A configurable data reduction model is proposed focused on periodic duty\u2013cycled sensor networks with events triggered by threshold. The loss of information produced by the model is analyzed in this paper in the context of event detection, an unusual approach leading to a set of specific metrics that enable the evaluation of the model in terms of traffic savings, precision, and recall. Different model configurations are tested with two experimental cases, whose input data are extracted from an extensive set of real data. In particular, two new versions of Send\u2013on\u2013Delta (SoD) and Predictive Sampling (PS) have been designed and implemented in the proposed data\u2013domain reduction for threshold\u2013based event detection (D2R-TED) model. The obtained results illustrate the potential usefulness of analyzing different model configurations to obtain a cost\u2013benefit curve, in terms of traffic savings and quality of the response. Experiments show an average reduction of 76 % of network packages with an error of less than 1%. In addition, experiments show that the methods designed under the proposed D2R\u2013TED model outperform the original event\u2013triggered SoD and PS methods by 10 % and 16 % of the traffic savings, respectively. This model is useful to avoid network bottlenecks by applying the optimal configuration in each situation.<\/jats:p>","DOI":"10.3390\/s18113806","type":"journal-article","created":{"date-parts":[[2018,11,7]],"date-time":"2018-11-07T03:45:22Z","timestamp":1541562322000},"page":"3806","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["D2R-TED: Data\u2014Domain Reduction Model for Threshold-Based Event Detection in Sensor Networks"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5363-1189","authenticated-orcid":false,"given":"Fernando","family":"Leon-Garcia","sequence":"first","affiliation":[{"name":"Department of Electronics and Computer Engineering, Edificio Leonardo da Vinci, Campus de Rabanales, Universidad de C\u00f3rdoba, 14071 C\u00f3rdoba, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5564-7889","authenticated-orcid":false,"given":"Jose Manuel","family":"Palomares","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Engineering, Edificio Leonardo da Vinci, Campus de Rabanales, Universidad de C\u00f3rdoba, 14071 C\u00f3rdoba, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2584-5491","authenticated-orcid":false,"given":"Joaquin","family":"Olivares","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Engineering, Edificio Leonardo da Vinci, Campus de Rabanales, Universidad de C\u00f3rdoba, 14071 C\u00f3rdoba, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1145\/2528948","article-title":"Compression in wireless sensor networks","volume":"10","author":"Razzaque","year":"2013","journal-title":"ACM Trans.
