We construct a warm inflation model with inflaton field non-minimally coupledto induced gravity on a warped DGP brane. We incorporate possible modificationof the induced gravity on the brane in the spirit of $f(R)$-gravity. We studycosmological perturbations in this setup. In the case of two field inflationsuch as warm inflation, usually entropy perturbations are generated. While itis expected that in the case of one field inflation these perturbations to beremoved, we show that even in the absence of the radiation field, entropyperturbations are generated in our setup due to non-minimal coupling andmodification of the induced gravity.
