The core feature of our system is a dynamic mobile node carried by an aerial robot, which ensures communication between sparse clusters located at fragmented parcels and a base station. This system overcomes some limitations of the wireless networks in areas with such characteristics. The use of a dedicated communication channel enables data routing to\/from unlimited distances.<\/jats:p>","DOI":"10.3390\/s110606088","type":"journal-article","created":{"date-parts":[[2011,6,7]],"date-time":"2011-06-07T11:47:49Z","timestamp":1307447269000},"page":"6088-6108","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":138,"title":["An Air-Ground Wireless Sensor Network for Crop Monitoring"],"prefix":"10.3390","volume":"11","author":[{"given":"Jo\u00e3o","family":"Valente","sequence":"first","affiliation":[{"name":"CAR UPM-CSIC, C\/Jose Gutierrez Abascal, 2, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Sanz","sequence":"additional","affiliation":[{"name":"CAR UPM-CSIC, C\/Jose Gutierrez Abascal, 2, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1691-3907","authenticated-orcid":false,"given":"Antonio","family":"Barrientos","sequence":"additional","affiliation":[{"name":"CAR UPM-CSIC, C\/Jose Gutierrez Abascal, 2, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4893-2571","authenticated-orcid":false,"given":"Jaime del","family":"Cerro","sequence":"additional","affiliation":[{"name":"CAR UPM-CSIC, C\/Jose Gutierrez Abascal, 2, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1ngela","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"CAR UPM-CSIC, C\/Jose Gutierrez Abascal, 2, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudio","family":"Rossi","sequence":"additional","affiliation":[{"name":"CAR UPM-CSIC, C\/Jose Gutierrez Abascal, 2, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2011,6,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kropff, M., Wallinga, J., and Lotz, L.
