  Recently the study of anomalous gamma-ray emission in the regions surrounding
the galactic center has drawn a lot of attention as it points out that the
excess of $\sim 1-3$ GeV gamma-ray in the low latitude is consistent with the
emission expected from annihilating dark matter. The best-fit to the gamma-ray
spectrum corresponds to dark matter (DM) candidate having mass in the range
$\sim 31-40$ GeV annihilating into $b\bar{b}$-pair with cross-section $\langle
\sigma v \rangle = (1.4-2.0)\times 10^{-26}\;\textrm{cm}^3 \textrm{sec}^{-1}$.
We have shown that the Higgs-portal dark matter models in presence of scalar
resonance (in the annihilation channel) are well-suited for explaining these
phenomena. In addition, the parameter space of these models also satisfy
constraints from the LHC Higgs searches, relic abundance and direct detection
experiments. We also comment on real singlet scalar Higgs-portal DM model which
is found to be incompatible with the recent analysis.
