A Fluid Model for Performance Analysis in Cellular Networks
Source: Telecom ParisTech
In this paper, the authors propose a new framework to study the performance of cellular networks using a fluid model and they derive from this model analytical formulas for interference, outage probability, and spatial outage probability. The key idea of the fluid model is to consider the discrete Base Stations (BS) entities as a continuum of transmitters that are spatially distributed in the network. This model allows the authors to obtain simple analytical expressions to reveal main characteristics of the network. In this paper, the authors focus on the downlink Other-Cell Interference Factor (OCIF), which is defined for a given user as the ratio of its outer cell received power to its inner cell received power.
