In the context of epidemic spreading over a network the problem of allocating a limited number of cure to curb the spreading is often discussed. While strategies exist for heterogeneous networks as scale-free networks (networks with a power-law degree distribution), we introduce here a new strategy for homogeneous networks as grid-like networks. To do so we use a scale-free abstraction of the network allowing to identify the most interesting zones to cure. Moreover we present a theoretical result linking the scale-free coefficient and the efficiency of the strategy of allocation in scale-free networks.
