Thus, maintaining connectivity of the communication graph is a fundamental issue in the field of multi-robot systems. In this paper we present a completely decentralized control strategy for global connectivity maintenance of the communication graph. Considering the disk communication model, we describe a gradient-based control strategy that exploits decentralized estimation of the algebraic connectivity. Unlike previous approaches available in the literature, the proposed control algorithm solves the global connectivity problem in a decentralized manner providing theoretical guarantees, without requiring maintenance of the local connectivity between robotic systems. Moreover, results obtained with simulations and experiments on real robots are described for demonstrating the efficacy of the proposed algorithm.<\/jats:p>","DOI":"10.1177\/0278364913499085","type":"journal-article","created":{"date-parts":[[2013,9,19]],"date-time":"2013-09-19T03:52:09Z","timestamp":1379562729000},"page":"1411-1423","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":152,"title":["Decentralized connectivity maintenance for cooperative control of mobile robotic systems"],"prefix":"10.1177","volume":"32","author":[{"given":"Lorenzo","family":"Sabattini","sequence":"first","affiliation":[{"name":"Department of Sciences and Methods for Engineering (DISMI), University of Modena and Reggio Emilia, Italy"}]},{"given":"Nikhil","family":"Chopra","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering and Institute for Systems Research, University of Maryland, College Park, MD, USA"}]},{"given":"Cristian","family":"Secchi","sequence":"additional","affiliation":[{"name":"Department of Sciences and Methods for Engineering (DISMI), University of Modena and Reggio Emilia, Italy"}]}],"member":"179","published-online":{"date-parts":[[2013,9,18]]},"reference":[{"key":"bibr1-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2010.2072570"},{"key":"bibr2-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2010.5717917"},{"key":"bibr3-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1515\/9781400831470"},{"key":"bibr4-0278364913499085","first-page":"4744","volume-title":"Proceedings of the American Control Conference","author":"Cao Y","year":"2010"},{"key":"bibr5-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2006.377041"},{"key":"bibr6-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cta.2009.0229"},{"key":"bibr7-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/TCST.2007.908214"},{"key":"bibr8-0278364913499085","doi-asserted-by":"publisher","DOI":"10.13001\/1081-3810.1014"},{"issue":"98","key":"bibr9-0278364913499085","first-page":"298","volume":"23","author":"Fielder M","year":"1973","journal-title":"Czechoslovak Mathematical Journal"},{"key":"bibr10-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2011.2161427"},{"key":"bibr11-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2009.5400723"},{"key":"bibr12-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2006.377078"},{"key":"bibr13-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4613-0163-9"},{"key":"bibr14-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/ROBOT.2010.5509175"},{"key":"bibr15-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1002\/rob.20221"},{"key":"bibr16-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/TRO.2007.900638"},{"key":"bibr17-0278364913499085","first-page":"99","volume-title":"Proceedings of the IEEE American Control Conference","author":"Kim Y","year":"2005"},{"key":"bibr18-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2005.1582595"},{"key":"bibr19-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2005.1583508"},{"key":"bibr20-0278364913499085","first-page":"59","volume-title":"Proceedings of the 9th Conference on Autonomous Robot Systems and Competitions","author":"Mondada F","year":"2009"},{"key":"bibr21-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2010.5717945"},{"key":"bibr22-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/ACC.2006.1656533"},{"key":"bibr23-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2006.887293"},{"key":"bibr24-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/IROS.2011.6094818"},{"key":"bibr25-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2011.6161067"},{"key":"bibr26-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/ICRA.2012.6224857"},{"key":"bibr27-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1109\/MED.2013.6608840"},{"key":"bibr28-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1145\/1288107.1288110"},{"key":"bibr29-0278364913499085","doi-asserted-by":"publisher","DOI":"10.1007\/s10846-009-9328-8"},{"key":"bibr30-0278364913499085","doi-asserted-by":"crossref","unstructured":"Schuresko M, Cort\u00e9s J (2009 b) Distributed Tree Rearrangements for Reachability and Robust Connectivity (Lecture Notes in Computer Science, vol. 5469).
