Leptogenesis is believed to be contributing to the baryon asymmetry of the Universe through baryogenesis. We consider a simple framework to understand the same with the extension of standard model with $S_3$ and $Z_2$ symmetry. We add two scalar triplets and right-handed neutrinos to explain the neutrino data. Moreover, we consider both type-I and type-II seesaw framework with scalar triplets and right-handed neutrinos to give us the required lepton asymmetry which can account for the observed baryon asymmetry of the universe. In doing so, we consider different mass scales for the scalar triplets and solve the Boltzmann equations to obtain the desire results. We also comment on the LFV and g-2 in the current framework.
