A Performance Study of Next Generation Cellular Networks with Base Stations Channels Vacations

The aim of this paper is to give a detailed modeling and performance analysis of Small Cell wireless Networks considering the limited number of mobiles served in each cell and different vacation schemes of the base stations channels, using the Generalized Stochastic Petri nets formalism. Hence, we show how this high level formalism allows a simple construction of detailed and compact models for such networks by considering single and multiple independent vacations of channels or all the base station in the case of synchronous vacations. In addition, we develop the formulas of the main stationary performance measures. Through numerical examples, we discuss the impact of channels number of the base station, vacation rate and vacation scheme on the network performances.
