Even though it is clear that these networks share common features with its predecessors, e.g., with mobile ad hoc networks and with vehicular ad hoc networks, there are several unique characteristics that make FANETs different. These distinctive features impose a series of guidelines to be considered for its successful deployment. Particularly, the use of FANETs for telecommunication services presents demanding challenges in terms of quality of service, energy efficiency, scalability, and adaptability. The proper use of models in research activities will undoubtedly assist to solve those challenges. Therefore, in this paper, we review mobility, positioning, and propagation models proposed for FANETs in the related scientific literature. A common limitation that affects these three topics is the lack of studies evaluating the influence that the unmanned aerial vehicles (UAV) may have in the on-board\/embedded communication devices, usually just assuming isotropic or omnidirectional radiation patterns. For this reason, we also investigate in this work the radiation pattern of an 802.11 n\/ac (WiFi) device embedded in a UAV working on both the 2.4 and 5 GHz bands. Our findings show that the impact of the UAV is not negligible, representing up to a 10 dB drop for some angles of the communication links.<\/jats:p>","DOI":"10.3390\/s18103571","type":"journal-article","created":{"date-parts":[[2018,10,23]],"date-time":"2018-10-23T08:43:36Z","timestamp":1540284216000},"page":"3571","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":129,"title":["Flying Ad Hoc Networks: A New Domain for Network Communications"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3067-6469","authenticated-orcid":false,"given":"Antonio","family":"Guillen-Perez","sequence":"first","affiliation":[{"name":"Department of Information and Communication Technologies, Universidad Polit\u00e9cnica de Cartagena, 30202 Cartagena, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4952-0325","authenticated-orcid":false,"given":"Maria-Dolores","family":"Cano","sequence":"additional","affiliation":[{"name":"Department of Information and Communication Technologies, Universidad Polit\u00e9cnica de Cartagena, 30202 Cartagena, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2624","DOI":"10.1109\/COMST.2016.2560343","article-title":"Survey on Unmanned Aerial Vehicle Networks for Civil Applications: A Communications Viewpoint","volume":"18","author":"Hayat","year":"2016","journal-title":"IEEE Commun.
