We present a TeV scale seesaw mechanism for exploring the dark matter andneutrino phenomenology in the light of recent neutrino and cosmology data. Adifferent realization of the Inverse seesaw(ISS) mechanism with $A_{4}$ flavorsymmetry is being implemented as a leading contribution to the light neutrinomass matrix which usually gives rise to vanishing reactor mixing angle$\theta_{13}$. Using a non-diagonal form of Dirac neutrino mass matrix and$3\sigma$ values of mass square differences we parameterize the neutrino massmatrix in terms of Dirac Yukawa coupling "$y$". We then use type II seesaw as aperturbation which turns out to be active to have a non-vanishing reactormixing angle without much disturbing the other neutrino oscillation parameters.Then we constrain a common parameter space satisfying the non-zero$\theta_{13}$, Yukawa coupling and the relic abundance of dark matter.Contributions of neutrinoless double beta decay are also included for standardas well as non-standard interaction. This study may have relevance in futureneutrino and Dark Matter experiments.
