Impact of Small Cells Location on Performance and QoS of Heterogeneous Cellular Networks

Abstract :

We propose an analysis of the impact of the deployment of small base stations in a wireless network constituted of macro base stations. This analysis is particularly focused on the influence of the position and the transmitting power of small base stations on the performance of the network. In this aim, we consider an analytical model for heterogeneous cellular networks, composed of macro cells and small cells. The network model framework developed allows to derive closed form formulas for the Signal to Interference plus Noise Ratio (SINR) received by a mobile, whatever its location. Moreover, the proposed analytical model is validated by numerical simulations and it is shown that it is a good approximation of the SINR. Performance and quality of service (QoS) in terms of throughput and coverage can therefore be analyzed in a simple way. It makes it possible to analyze the deployment of small cells in an existing macro cells network.
