We study cosmological inflation and its dynamics in the framework of theRandall-Sundrum II brane model. In particular, we analyze in detail fourrepresentative small-field inflationary potentials, namely Natural inflation,Hilltop inflation, Higgs-like inflation, and Exponential SUSY inflation, eachcharacterized by two mass scales. We constrain the parameters for which aviable inflationary Universe emerges using the latest PLANCK results.Furthermore, we investigate whether or not those models in brane cosmology areconsistent with the recently proposed Swampland Criteria, and give predictionsfor the duration of reheating as well as for the reheating temperature afterinflation. Our results show that (i) the distance conjecture is satisfied, (ii)the de Sitter conjecture and its refined version may be avoided, and (iii) theallowed range for the five-dimensional Planck mass, $M_5$, is found to bebetween $10^5~\textrm{TeV}$ and $10^{12}~\textrm{TeV}$. Our main findingsindicate that non-thermal leptogenesis cannot work within the framework ofRS-II brane cosmology, at least for the inflationary potentials consideredhere.
