     INTRODUCTION

    Summary

    The exponentially growing demand for wireless communications services calls for a massive increase in network density, a solution that is neither economical nor environmentally friendly within the framework of current communications networks. The concept of Small Cell Networks (SCN), based on the idea of a very dense deployment of small, inexpensive base stations, is a possible alternative. There are potential financial and ecological benefits, as well as technological challenges, associated with the large-scale deployment of SCNs. An overview of the research problems and the tools needed to study them are presented.

    Abstract

    The exponentially increasing demand for wireless data services requires a massive network densification which is neither economically nor ecologically viable with current cellular system architectures. A potential solution to this problem is the concept of small cell networks (SCNs) which are founded on the idea of a very dense deployment of self-organizing low-cost low-paper base stations. In this article, potential financial and ecological benefits as well as the technical challenges related to a large-scale deployment of SCNs are discussed. Moreover, an overview of related research problems and the necessary tools for their study is provided.
