  Understanding the properties of dark matter has proved to be one of the most
challenging problems of particle phenomenology. In this paper, we have tried to
understand the phenomenology of dark matter in light of very well understood
properties of cosmic microwave background (CMB) anisotropy. To connect these
two, inflation and its subsequent evolution known as the reheating phase play
the important role. Following the previous analysis, we first established a
one-to-one correspondence between the CMB power spectrum and the reheating
temperature assuming the perturbative reheating scenario. Further by
incorporating a possible dark matter candidate through the radiation
annihilation process during reheating and the current value of dark matter
abundance, we constrain the dark matter parameter space through the
inflationary power spectrum for different inflationary models.
