Abstract

In this paper we reconsider the accelerated expansion phenomenon in the DGP braneworld scenario which leads to an accelerated universe without cosmological constant or other form of dark energy for the positive branch epsilon= +1 which is not more attractive model Thus we assume the DGP braneworld scenario with epsilon= 1 and also interacting Hubble and event horizons pilgrim dark energy models We extract various cosmological parameters in this scenario and displayed our results with respect to redshift parameter It is found that the ranges of Hubble parameter are coincided with observational results The equation of state parameter lies within the suggested ranges of different observational schemes The squared speed of sound shows stability for all present models in DGP braneworld scenario The omega varthetaomega vartheta planes lie in the range omega vartheta=113+024 025omega vartheta132 which has been obtained through different observational schemes It is remarked that our results of various cosmological parameters shows consistency with different observational data like Planck WP BAO H 0 and SNLS
