Abstract:
The ever-increasing number of customers and the need for higher data rates and multimedia services require the deployment of Small Cell Networks. This paper considers modeling, performance evaluation and reliability of Small Cell Wireless Networks, taking into account the retrial phenomenon, finite number of customers served in a cell and channels breakdowns. The aim of this paper is to give a detailed performance and reliability analysis of these next-generation networks considering different breakdowns disciplines using Generalized Stochastic Petri nets formalism. The novelty of this investigation consists in the consideration of two breakdowns disciplines: channels breakdowns and base station (synchronous) breakdowns. For the first one, each channel is an independent working unit, and it can fail independently of other channels state. For the second one, the breakdowns are synchronous, hence all the channels of the base station fail down simultaneously. Hence, we show how this high level model allows us to cope with the complexity of such finite-source retrial networks, under the different breakdowns disciplines and how several steady-state performance and reliability indices can be derived. Through numerical examples, we discuss the effect of the network parameters on performance.
