Inter-cell cooperation aided dynamic base station switching for energy efficient cellular networks

In this paper, a cell zooming based dynamic base stations (BS) switching scheme is conceived for energy saving in cellular networks. A cell zooming algorithm is developed for leveraging the BS's coverage with inter-cell cooperation and downlink power control. Meanwhile, we design a feasible working strategy for the cell zooming scheme to maximizing the energy saving. Simulations are provided to demonstrate the advantages of the proposed scheme.
