  We present a TeV scale seesaw mechanism for exploring the dark matter and
neutrino phenomenology in the light of recent neutrino and cosmology data. A
different realization of the Inverse seesaw(ISS) mechanism with $A_{4}$ flavor
symmetry is being implemented as a leading contribution to the light neutrino
mass 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 mass
matrix in terms of Dirac Yukawa coupling "$y$". We then use type II seesaw as a
perturbation which turns out to be active to have a non-vanishing reactor
mixing 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 standard
as well as non-standard interaction. This study may have relevance in future
neutrino and Dark Matter experiments.
