Base station cooperation for energy efficiency: A Gauss-poisson process approach

Base station cooperation is an effective means of improving the spectral efficiency of cellular networks. From an energy-efficiency perspective, whether base station cooperation benefits the network performance remains an issue to be answered. In this paper, we adopt tools from stochastic geometry to treat this issue. Specifically, we model the cooperating base stations as clusters in a Gauss-Poisson process, a variant of the usually considered Poisson point processes. We compare the performance in terms of energy efficiency with and without base station cooperation. The results reveal that only when the cooperative base stations account for a large proportion of all the base stations will the cooperation among base stations bring gains to the energy efficiency of the network.
