  We have studied the scotogenic model proposed by Ernest Ma, which is an
extension of the Standard Model by three singlet right-handed neutrinos and a
scalar doublet. This model proposes that the light neutrinos acquire a non-zero
mass at 1-loop level. In this work, the realisation of the scotogenic model is
done by using discrete symmetries $A_{4}\times Z_{4}$ in which the non-zero
$\theta_{13}$ is produced by assuming a non-degeneracy in the loop factor.
Considering different lepton flavor violating(LFV) processes such as
$l_{\alpha}\longrightarrow l_{\beta}\gamma$ and $l_{\alpha}\longrightarrow
3l_{\beta}$, their impact on neutrino phenomenology is studied. We have also
analysed $0\nu\beta\beta$ and baryon asymmetry of the Universe (BAU) in this
work.
