  Considering the modified entropy-area relation from DSR-GUP (Doubly special
relativity-Generalized uncertainity principle), we obtain the modified
Friedmann equations from the first law of thermodynamics at apparent horizon.
Due to the importance of GUP at Planck scale, we investigate the Friedmann
equations and show the maximum energy density \r{ho} at Planck scale. Since GUP
implies a minimal length, we find a minimum apparent horizon which has a
potential to remove the Big Bang singularity. Furthermore, we analyse the
effects of DSR-GUP on deceleration parameter q for the equation of state p =
{\omega}\r{ho} and the flat case. Finally, we check the validity of the
generalized second law (GSL) of thermodynamics and show that it is valid all
eras of the Universe for any spatial curvature.
