Abstract
The VVV survey is observing the central regions of our Galaxy in the near-infrared, where the extinction is highly diminished, in several epochs. Numerous inner Galactic globular clusters fall inside the area covered by the VVV survey. Most of these clusters, especially the faintest ones, have been poorly studied due to the presence of severe extinction and high stellar densities in the field. We have started a search for variable stars in these clusters. Our main aim is to obtain a better determination of the physical parameters of these globular clusters using the information provided by their variables.
