  Gauge theory of gravity is formulated based on principle of local gauge
invariance. Because the model has strict local gravitational gauge symmetry,
gauge theory of gravity is a perturbatively renormalizable quantum model.
However, in the original model, all gauge gravitons are massless. We want to
ask that whether there exists massive gravitons in Nature? In this paper, we
will propose a gauge model with massive gravitons. The mass term of
gravitational gauge field is introduced into the theory without violating the
strict local gravitational gauge symmetry. Massive gravitons can be considered
to be possible origin of dark energy and dark matter in the Universe.
