  A dS brane on the boundary between two five-dimensional spacetimes is
determined. We consider asymmetric scenarios with AdS${}_5$ vacua at each side
of the dS brane; and as a result, a resonant mode inside of the spectrum of the
gravitational fluctuations is found. We analyze the deviations to the Newton
potential generated by the gravitational excitations, finding that, for
scenarios with large values of the cosmological constants, the contribution of
the resonant mode is exponentially suppressed. However, when one of the vacua
is null, the resonant mode belongs to the light states set of the gravitational
fluctuations and five-dimensional gravity is recovered on the dS brane.
