| contents | In this paper, we analyze the agegraphic dark energy from the entropy of the anti-de Sitter black hole using the age of the universe as the IR cutoff. We constrain its parameter with the Pantheon+ Type Ia supernova sample and observational Hubble parameter data, finding that the Akaike Information Criterion cannot effectively distinguish this model from the standard $Λ$CDM model. The present value of Hubble constant $H_{0}$ and the model parameter $b^{2}$ are constrained to $H_{0}=67.7 \pm 1.8$ and $b^{2}=0.303^{+0.019}_{-0.024}$. This model realizes the whole evolution of the universe, including the late-time accelerated expansion. Although it asymptotically approaches the standard $Λ$CDM model in the future, statefinder analysis shows that late-time deviations allow the two models to be distinguished. |
