  We study a neutrino mass model with $A_4$ discrete flavor symmetry using a
type-I seesaw mechanism. The inclusion of extra flavons in our model leads to
the deviations from exact tribimaximal mixing pattern resulting in a nonzero
$\theta_{13}$ consistent with the recent experimental results and a sum rule
for light neutrino masses is also obtained. In this framework, a connection is
established among the neutrino mixing angles: reactor mixing
angle($\theta_{13}$), solar mixing angle($\theta_{12}$) and atmospheric mixing
angle ($\theta_{23}$). This model also allows us a prediction of Dirac CP-phase
and Jarlskog parameter $J$. The octant of the atmospheric mixing angle
$\theta_{23}$ occupies the lower octant. Our model prefers normal hierarchy
(NH) than inverted hierarchy (IH). We use the parameter space of our model of
neutrino masses to study the neutrinoless double beta decay parameter $m_{ee}$.
