  The Diffuse Supernova Neutrino Background (DSNB) in the MeV regime represents
the cumulative cosmic neutrino emission, predominantly due to core collapse
supernovae. We estimate the DSNB flux for different Star Formation Rate Density
(SFRD) models. We find that the DSNB flux estimated using the SFRD derived from
Fermi-LAT Collaboration et al. (2018) is significantly higher ($\approx$
32$\%$) relative to the flux estimated using the SFRD from Madau & Fragos
(2017). This depicts the sensitivity between the DSNB flux and the SFRD
estimates which shows that future detection of the DSNB can be used as a
valuable tool to constrain the SFRD.
