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 $0 ubetabeta$ and baryon asymmetry of the Universe (BAU) in this work.
