We present an holographic model of the Dvali-Gabadadze-Porrati scenario witha Gauss-Bonnet term in the bulk. We concentrate on the solution thatgeneralises the normal Dvali-Gabadadze-Porrati branch. It is well known thatthis branch cannot describe the late-time acceleration of the universe evenwith the inclusion of a Gauss-Bonnet term. Here, we show that this branch inthe presence of a Gauss-Bonnet curvature effect and an holographic dark energywith the Hubble scale as the infra-red cutoff can describe the late-timeacceleration of the universe. It is worthwhile to stress that such an energydensity component cannot do the same job on the normal Dvali-Gabadadze-Porratibranch (without Gauss-Bonnet modifications) nor in a standard 4-dimensionalrelativistic model. The acceleration on the brane is also presented as beinginduced through an effective dark energy which corresponds to a balance betweenthe holographic one and geometrical effects encoded through the Hubbleparameter.
