Endothelial permeability assay was...
In this paper, we intend to study the optimal deployment density of drone small cells (DSCs) achieve maximum coverage considering inter-cell interference. Due high altitude, air-to-ground channel DSCs consist probabilistic line-of-sight (LoS) and non-line-of-sight (NLoS) links, causing computational difficulties in performance analysis. To accurately analyze performance, calculate cumulative interference both LoS NLoS links. And derive an approximate closed-form expression for it facilitate...
