In this paper, a novel Fuzzy-logic Topology Control (FTC) is proposed to achieve any desired average node degree by adaptively changing communication range, thus improving the network connectivity, which is the main target of FTC. FTC is a fully localized control algorithm, and does not rely on location information of neighbors. Instead of designing membership functions and if-then rules for fuzzy-logic controller, FTC is constructed from the training data set to facilitate the design process. FTC is proved to be accurate, stable and has short settling time. In order to compare it with other representative localized algorithms (NONE, FLSS, k-Neighbor and LTRT), FTC is evaluated through extensive simulations. The simulation results show that: firstly, similar to k-Neighbor algorithm, FTC is the best to achieve the desired average node degree as node density varies; secondly, FTC is comparable to FLSS and k-Neighbor in terms of energy-efficiency, but is better than LTRT and NONE; thirdly, FTC has the lowest average maximum communication range than other algorithms, which indicates that the most energy-consuming node in the network consumes the lowest power.<\/jats:p>","DOI":"10.3390\/s140304672","type":"journal-article","created":{"date-parts":[[2014,3,7]],"date-time":"2014-03-07T11:44:38Z","timestamp":1394192678000},"page":"4672-4688","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["A Novel Topology Control Approach to Maintain the Node Degree in Dynamic Wireless Sensor Networks"],"prefix":"10.3390","volume":"14","author":[{"given":"Yuanjiang","family":"Huang","sequence":"first","affiliation":[{"name":"Centro de Investigaci\u00f3n en Tecnolog\u00edas Software y Sistemas Multimedia para la Sostenibilidad (CITSEM), Campus Sur Universidad Polit\u00e9cnica de Madrid (UPM), 28031 Madrid, Spain"}]},{"given":"Jos\u00e9-Fern\u00e1n","family":"Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n en Tecnolog\u00edas Software y Sistemas Multimedia para la Sostenibilidad (CITSEM), Campus Sur Universidad Polit\u00e9cnica de Madrid (UPM), 28031 Madrid, Spain"}]},{"given":"Vicente","family":"D\u00edaz","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n en Tecnolog\u00edas Software y Sistemas Multimedia para la Sostenibilidad (CITSEM), Campus Sur Universidad Polit\u00e9cnica de Madrid (UPM), 28031 Madrid, Spain"}]},{"given":"Juana","family":"Sendra","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n en Tecnolog\u00edas Software y Sistemas Multimedia para la Sostenibilidad (CITSEM), Campus Sur Universidad Polit\u00e9cnica de Madrid (UPM), 28031 Madrid, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2014,3,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1007\/978-3-540-69395-6_2","article-title":"Percolation, Connectivity, Coverage and Colouring of Random Geometric Graphs","volume":"Volume 18","author":"Balister","year":"2008","journal-title":"Bolyai Society Mathematical Studies"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"307","DOI":"10.1109\/TPDS.2006.51","article-title":"Localized fault-tolerant topology control in wireless ad hoc networks","volume":"17","author":"Li","year":"2006","journal-title":"IEEE Trans.
