  The light singlino-like neutralino is expected to be a promising candidate
for DM in the allowed parameter space of the NMSSM. The DM annihilation process
takes place via the light Higgs bosons which are natural in this model.
Identifying the allowed region of parameter space including various
constraints, the detection prospect of such light DM candidate and Higgs bosons
are explored at the LHC with its high luminosity options. Light Higgs bosons
and the DM candidate, the lightest singlino-like neutralino are indirectly
produced at the LHC via the SM Higgs production and its subsequent decays. Jet
substructure techniques are used to tag boosted Higgs. It is found that the
favourable range of masses of Higgs bosons and neutralino, compatible with a
low mass DM solution, can be discovered with a reasonable signal significance
($\sim 5 \sigma$) at the LHC, with the center of mass energy $\sqrt{s}=14$ TeV
and integrated luminosity options $\rm{\cal L}=300~fb^{-1}$ and 3000 $\rm
fb^{-1}$.
