This paper proposes cell group selection with backhaul\u2010aware biasing for UAV networks and analyzes system performance by deriving the rate outage probability via stochastic geometry, where the user\u2019s maximum data rate is constrained by backhaul capacity. Specifically, cell group selection is no longer distance\u2010based and considered with backhaul capacity bias factor, where UAVs with higher backhaul capacity will have a larger bias factor to match the backhaul variance. In addition, the dynamic UAV group is organized with the <jats:italic>N<\/jats:italic> largest bias reference signal receiving power (BRSRP), where users can utilize the diversity gain by adjusting serving UAV dynamically as the channel conditions change. Analytical results show that the outage probability is decreased by 58% when cell group size <jats:italic>N<\/jats:italic> = 3 and UAV optimal density <jats:italic>\u03bb<\/jats:italic><jats:sub><jats:italic>u<\/jats:italic><\/jats:sub> = 600\/km<jats:sup>2<\/jats:sup> when UAV height <jats:italic>h<\/jats:italic> = 150\u2009m.<\/jats:p>","DOI":"10.1155\/2021\/3929514","type":"journal-article","created":{"date-parts":[[2021,7,7]],"date-time":"2021-07-07T20:35:15Z","timestamp":1625690115000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Performance Analysis of Group Selection in UAV Networks with Backhaul\u2010Aware Biasing"],"prefix":"10.1155","volume":"2021","author":[{"given":"Shusheng","family":"Wang","sequence":"first","affiliation":[]},{"given":"Yuanyuan","family":"Du","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2031-5985","authenticated-orcid":false,"given":"Hongtao","family":"Zhang","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,7,7]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2018.1700666"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2019.2902862"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2017.1600238CM"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2018.2887086"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2019.2938168"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2020.3024686"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/LWC.2020.3012554"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2020.3019320"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/LWC.2018.2869804"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2020.3010845"},{"key":"e_1_2_10_11_2","doi-asserted-by":"crossref","unstructured":"LiP.andXuJ.
