In this paper, some FRW models exhibiting late-time acceleration are obtained in the presence of an interacting dark energy represented by a time varying cosmological constant in general theory of relativity. In order to solve the Einstein’s field equations, we have considered a simple parametrization of the
energy density ρ connecting radiation and matter dominated eras. Some features of the obtained models are then discussed.
