Abstract

In this paper, we propose an analytical framework for energy saving and outage performance of two-tier heterogeneous networks with traffic-based varying inter-tier dependence. Firstly, the Macro Base Station (MBS) tier and Pico Base Station (PBS) tier are deployed following a Poisson Point Process (PPP) and a Poisson Hole Process (PHP) respectively. Then, the exclusion radius of the MBS is designed to be inversely proportional to the data traffic modeled as a periodic sinusoidal model. Hinging on the proposed analytical framework, tractable expressions are derived for energy consumption and outage performance of Heterogeneous Cellular Network (HCN). From the analytical and simulation results it can be concluded that the outage performance of Macro Users (MUs) with our scheme outperforms that of the independent HCN model and the intertier dependent HCN model with fixed exclusion radius, while the outage performance of Pico Users (PUs) decreases only a little, and up to 15% energy can be saved with our scheme.
