In such a context, building a system to monitor environmental hazards is seriously needed. Some studies propose to use wireless sensor network (WSN) technique for landslide monitoring systems. Two important factors for these systems are the flexibility and the energy management. This paper focuses on the development of a flexible and efficient WSN for detecting rainfall-induced landslides. A flexible switching between star and tree topologies is used to adapt to weather conditions in order to maximize the reliability of the transmission. Moreover, the power management is designed concurrently with the weather condition to improve both the operation reliability and the power efficiency. The performance of our designed WSN is evaluated by both simulation and outdoor experiment. Detailed calculation of the power budget is presented thoughtfully to confirm the effectiveness of the proposed scheme. <\/jats:p>","DOI":"10.1155\/2015\/235954","type":"journal-article","created":{"date-parts":[[2015,11,10]],"date-time":"2015-11-10T21:00:59Z","timestamp":1447189259000},"page":"235954","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Flexible and Efficient Wireless Sensor Networks for Detecting Rainfall-Induced Landslides"],"prefix":"10.1177","volume":"11","author":[{"given":"Chinh D.","family":"Nguyen","sequence":"first","affiliation":[{"name":"Faculty of Electronics and Telecommunication, VNU University of Engineering and Technology, Hanoi, Vietnam"}]},{"given":"Tan D.","family":"Tran","sequence":"additional","affiliation":[{"name":"Faculty of Electronics and Telecommunication, VNU University of Engineering and Technology, Hanoi, Vietnam"}]},{"given":"Nghia D.","family":"Tran","sequence":"additional","affiliation":[{"name":"Institute of Information Technology, Vietnam Academy of Science and Technology, Hanoi, Vietnam"}]},{"given":"Tue Huu","family":"Huynh","sequence":"additional","affiliation":[{"name":"VNU International University, Ho Chi Minh City, Vietnam"}]},{"given":"Duc T.","family":"Nguyen","sequence":"additional","affiliation":[{"name":"VNU International University, Ho Chi Minh City, Vietnam"}]}],"member":"179","published-online":{"date-parts":[[2015,11,10]]},"reference":[{"key":"B1-2015-235954","doi-asserted-by":"publisher","DOI":"10.1016\/j.adhoc.2012.09.002"},{"key":"B2-2015-235954","doi-asserted-by":"publisher","DOI":"10.1145\/1127777.1127797"},{"key":"B3-2015-235954","doi-asserted-by":"publisher","DOI":"10.12928\/telkomnika.v9i1.640"},{"key":"B4-2015-235954","doi-asserted-by":"publisher","DOI":"10.5194\/adgeo-2-305-2005"},{"key":"B14-2015-235954","doi-asserted-by":"publisher","DOI":"10.1016\/j.enggeo.2014.06.024"},{"key":"B5-2015-235954","doi-asserted-by":"publisher","DOI":"10.1109\/iecon.2012.6389102"},{"key":"B6-2015-235954","doi-asserted-by":"publisher","DOI":"10.1109\/ichit.2008.172"},{"key":"B7-2015-235954","doi-asserted-by":"publisher","DOI":"10.1109\/65.953229"},{"key":"B8-2015-235954","doi-asserted-by":"publisher","DOI":"10.1109\/icisip.2006.4286057"},{"key":"B9-2015-235954","doi-asserted-by":"publisher","DOI":"10.1109\/pimrc.2013.6666469"},{"issue":"10","key":"B10-2015-235954","first-page":"223","volume":"157","author":"Wang W.","year":"2013","journal-title":"Sensors and Transducers"},{"issue":"6","key":"B11-2015-235954","first-page":"202","volume":"30","author":"Nguyen D.
